Angle sensors

Non-contact angle sensors are now programmable

Variohm EuroSensor has launched a new software application for communication and programming of Contelec Vert-X series non-contacting and contactless angle sensors. As British distributor for the Swiss manufactured range, Variohm offer OEMs (and machine builders?) the ability to reconfigure and customise the sensor curve and output characteristics over its 0º to 360º measurement range.

With on-assembly sensor configuration, the software has the potential to simplify stock control and reduce build and design timescales by removing the need to purchase several different types of angle sensor across different machines. Furthermore, the flexibility offered will allow specialist machine manufacturers the ability to program critical angle measurement characteristics such as joystick deadband, gearbox backlash or dancer arm neutral zone angles directly on the machine to suit performance requirements.

Vert-X Commander software is a simple-to-use PC based application supplied with a special cable that connects Singleturn Vert-X sensors via an Aardvark USB host adapter. A GUI displays programmable and fixed information from the sensors’ digital interface. Programmable parameters include a selection of six different sensor types with varying gradient, dead band and curve characteristics. For each sensor type, the user can typically set specific voltage output and specify left and right angles with an adjustable deadband (or gap) angle. The information is displayed in a graph showing sensor angle vs. voltage with a trace scaling function that allows closer examination of the output curve. When the desired characteristics have been set on screen, a program key simply downloads the data to the sensor, overwriting the previously programmed information. Fixed displayed parameters include the sensor angle, output voltage level and as primary quality control measure, the sensor serial number and a counter that records the number of times the sensor has been reprogrammed.

The compact and durable Vert-X range is aimed at precision, 0º to 360º, angle measurement spanning applications from analytical instruments to extremely heavy-duty applications such as agricultural machinery, autosports and automated industrial equipment where long life, high reliability and robust construction is required - often in space restricted areas.

These sensors use hall-effect magnetic measuring technology, offering high precision angle measurement in two design versions. Singleturn ‘contactless’ Vert-X sensors are characterised with bearing support for the rotating magnet and fixed sensor whereas Singleturn ‘non-contact’ Vert-X sensors are supplied in a two part sensor and magnet design for free mounting. Both types may be used in normal ambient environments through to long life and zero maintenance use in the most arduous and adverse conditions of high humidity, dampness, oil, dust and vibration.

Signal generator

New RF Vector Signal Generator provides Industry’s best Combination of high Throughput and low Phase Noise

Keithley Instruments has upgraded its popular RF Vector Signal Generator line for RF engineers with new capabilities that reduce signal generation times and enhance signal quality. In contrast with competitive signal generators, which typically force users to choose between best signal quality and maximum test throughput, the Model 2920A’s no-compromise design combines both capabilities in the same instrument. Patent-pending technology allows the Model 2920A RF Vector Signal Generator to support both frequency and amplitude switching rates that are significantly faster than any competitive system. Unlike systems optimized either for development or production, it is a cost-effective solution whether used on the bench for design verification testing or in production testing.



Continuing Technical Leadership in MIMO Testing
The Model 2920A is the latest addition to Keithley’s MIMO (Multiple-Input, Multiple-Output) testing system solutions. MIMO signals can be easily generated and analyzed by using Keithley’s SignalMeister™ RF Communications Test Toolkit software and Model 2820A Vector Signal Analyzers in conjunction with Model 2920As. When used in conjunction with the signal personalities provided in SignalMeister software, it is not only capable of generating pure signals but can generate impaired signals for in-depth receiver characterization and testing.
Model 2920A Applications
Applications include R&D, product development, and production testing of a growing range of wireless products such as femtocells, access points, mobile devices, wireless modules and air cards, and wireless chipsets. The Model 2920A’s operating mode flexibility makes it an excellent choice for MIMO device and system R&D applications, as well as in engineering education settings.

The Model 2920A, which provides signal generation bandwidth options up to 80MHz with a frequency range of either 10MHz–4GHz or 10MHz–6GHz, builds on the capabilities of Keithley’s Series 2900 signal generator line. It expands the Series 2900 line’s applications for testing wireless devices to today’s high throughput, complex modulation, and wide bandwidth wireless telecom standards, including LTE, GSM/EDGE, cdmaOne, cdma2000, W-CDMA, HSPA, HSPA+, LTE, WLAN, WiMAX, WiBro, TD-SCDMA, DVB (Digital Video Broadcast), and GPS (Global Positioning System).

The unit is optimised for calibrating and testing components such as amplifiers, filters, and wireless receivers thoroughly over their full range of performance at exceptional speed. Several major advances allow it to provide substantially higher test throughput than earlier signal generation options:

  • Industry’s fastest frequency tuning: A new, patent-pending technique that ensures fast settling of phase-locked loop synthesizers allows the Model 2920A to tune to a new frequency on a device under test’s (DUT’s) operating band in 300μs or less. Competitive products typically require 600μs or longer to tune to a new frequency.
  • Industry’s fastest amplitude switching: The Model 2920A provides electronic attenuation and a fast-tracking, automatic level control loop to stabilize quickly on a new power level, which allows switching to a new amplitude in as little as 150ms (compared to more than 500μs for competitive generators). This fast settling time speeds testing a device over its full power handling range.
  • Waveform switching in a single clock cycle: Because devices that operate on multiple standards require rapid switching between numerous complex signals during testing, the Model 2920A’s on-board arbitrary waveform generator includes a 100-megasample memory to hold large individual waveforms or multiple smaller ones. This deep memory, combined with the instrument’s speed-optimized list mode and a sequencer operating mode, supports switching from one waveform to another within a single processor clock cycle—even with waveforms based on different standards that use different modulation schemes.
  • High speed signal file transfers: The Model 2920A offers a direct link from its DSP processing circuit block to an external PC via a USB 2.0 bus that maximizes operating speed. In this high-speed Desktop Control Panel operating mode, an external PC assumes control of the Model 2920A, just as if it were the instrument’s on-board processor controller. This mode supports transferring signal files from a PC directly into the Model 2920A’s arbitrary waveform memory at 100Mb/sec for faster, simpler downloading of extremely large files (such as streaming video test signal files, signal files modified by channel models, and radar profile files). When combined with its high download speed and Keithley applications software, the Model 2920A can perform fast, efficient Dynamic Frequency Selection (DFS) conformance testing on WLAN access points. This test package allows verifying a device’s compliance with FCC, ETSI, and TELEC requirements related to ensuring that WLAN access point transmissions detect and do not interfere with government radar signals (such as weather radar or air traffic control radar).

    Users have the flexibility to create waveform files offline and download them into its arbitrary waveform memory using a USB memory stick or the GPIB or LAN interfaces. This transfer flexibility will be useful for those who prefer to employ third-party tools to create signal files, such as The MathWorks’ MATLAB® interactive programming environment.

    The Model 2920A’s enhanced speed performance doesn’t compromise its phase noise performance. Unlike competitive signal generators, which are typically designed to maximize either throughput (for production test applications) or signal purity (for design verification applications), it includes new capabilities that allow optimizing for whichever performance aspect is most critical for a specific application:

  • Ultra-low phase noise option: High signal purity is essential when creating complex HSPA+, 802.11n WLAN, 802.16e WiMAX, and LTE signals. To ensure the quality of these signals, the Model 2920A-UPN Ultra Low Phase Noise option provides phase noise ≤-135dBc/Hz at a 300kHz offset on a 2GHz carrier. That allows generating WCDMA signals with EVMs <0.85%. This option also permits the Model 2920A to generate 5.8GHz, 40MHz bandwidth WLAN 802.11n signals with an EVM of less than ‑43dB and WiMAX signals with a residual RCE (Relative Constellation Error) ≤-43dB. Just as important, the Model 2920A provides no-compromise tuning times as fast as 750µs when the low phase noise option is used.
  • Low amplitude range option: The Model 2920A’s wide signal range makes it ideal for testing a broad spectrum of receivers and components. The Model 2920A-LAR Low Amplitude Range option extends that range to allow the generator to output signals as low as ‑130dBm or as high as +13dBm. In addition, the Model 2920A offers excellent accuracy, repeatability, and stability specifications, so test system designers can set narrow limit bands in their test protocols, helping to ensure higher product quality:
    • Absolute amplitude accuracy of ±0.6dB (typically ±0.3dB) from
      -110dBm to +13dBm up to 3GHz
    • ±0.05dB relative amplitude accuracy (linearity)
    • ±0.05dB amplitude repeatability


    Availability
    The Model 2920A’s combination of high speed and high quality signal generation performance makes its pricing even more competitive because users can perform multiple applications with the same instrument—from design verification testing to production testing—extending the usage of each unit purchased. Option prices, whether the ultra-low phase noise option or optional personalities tailored to various telecom standards, are also at or below the cost of competitive solutions. Orders are being taken now for delivery in six weeks.
  • Indicating pressure

    Resisting fretting rust

    No need to fret!
    Shaft coating allows quick gearbox removal


    Nord Drivesystems has developed a specialised surface treatment option for hollow drive shafts that resists the formation of fretting rust or friction corrosion - reducing wear and facilitating the easy removal of gear motors for gearbox and motor servicing or replacement.

    Fretting rust or friction corrosion occurs in fixed mechanical joints under load and vibration where at least one surface material contains iron. Whilst it is commonly associated with bolted tension members in structures like bridges, the phenomenon is also seen in splines and drive shafts (even stainless steel versions), where the clamped drive and driven shaft surfaces actually experience microscopic levels of relative motion and slippage.

    The oxidised debris is an abrasive material that contributes to increased wear and, much more of a problem for drive shafts, the miniscule fragments become compressed between the surfaces often making removal extremely difficult - sometimes resulting in costly shaft damage.

    Nord’s RS coating option, available across its wide range of gearmotors, produces an extremely hard wearing and corrosion resistant layer of approximately 10 microns thickness that reduces surface friction characteristics of the hollow shaft and significantly reduces the formation of fretting rust. The treatment allows effortless gearmotor shaft removal and eliminates the potential for destruction of the insert shaft, saving costs by minimising maintenance and repair timescales.

    Breath alcohol

    Temperature sensors for breath alcohol instrument

    The Lion Alcolmeter® 500 is a breath alcohol measuring instrument designed for field use and extensively used by public services and other authorities for fast subject screening to ensure safe alcohol levels, in many instances before a vehicle or dangerous machinery is actually operated. The British Home Office approved instrument fully complies with the stringent accuracy and reliability standards for such equipment which uses high reliability temperature sensors from BetaTHERM Inc, supplied by its exclusive British distribution partner Variohm EuroSensor.

    Temperature sensors used in breath alcohol instruments are essential to maintain that the subject breath temperature falls within an acceptable range and to provide the means to compensate for minute breath temperature variance for the test result. Along with other measured criteria, breath temperature levels help to determine the validity of the breath sample – if for any reason the temperature is out of its normal and relatively narrow range, the Alcolmeter 500 will register an alarm.

    To maintain such a high specification, the alcolmeter 500 uses ultra-small bead thermistors. These sensors utilise metallic oxide semiconductor material sintered on platinum/iridium alloy lead wires with a controlled glass coating which provides a hermetic seal. With fast response times and high power sensitivities, the technology is well suited to gas flow or liquid temperature measurement and their small size (0.25 mm diameter) make them ideal for portable instruments. Other applications for this high reliability temperature sensor are gas chromatography and thermal conductivity gas analysis equipment.

    This range of thermistors are used in demanding temperature measurement, control and compensation applications in biomedical, automotive, aerospace, instrumentation, HVAC, consumer industries and instrumentation. The range enjoys the highest reputation for total reliability and uncompromising accuracy and Variohm provide complete technical support from customer product development through to full production.

    Installation rails

    Rapid installation rails for fast enclosure configuration

    Specifying the right enclosure for the right application can depend on a number of variables such as size, environment and material used. Accessories however, which are used to customise an enclosure, can also play a strategic part in determining its performance. Rittal now offer special interior installation rails for the fast configuration of its AE compact enclosures. Using this new mounting technique ensures the protection category of the enclosure remains unaffected due to the absence of any drilling.

    The newly developed interior installation rails and accessories such as door-operated switches, lights, punched sections, door supports, thermostats and hygrostats can be inserted without the need to drill any additional holes in the enclosure. Simply insert the rails against the rear panel of the enclosure and screw into the front enclosure edge.

    Rittal interior installation rails are available for AE Enclosure with depths of 210, 250, 300 and 350mm.

    Harsh pressure!

    Pressure sensors for harsh environments

    Three new ranges of high performance, pressure sensors from Kistler Instruments use a new, patented double lip sealing method to eliminate the need for an O-ring seal to ensure accuracy and reliability where extremely high temperature, vibration and shock are likely. Contained in a high integrity housing, the piezoresistive sensing element is isolated from the pressure media by a welded 316L stainless steel or Hastelloy™ diaphragm. Integrated surface mount electronics provide signal conditioning and temperature compensation. .

    The three ranges consist of absolute (Type 4260A), gauge (Type 4262A) and differential (4264A) with an accuracy of up to 0.05% FS and long-term stability of 0.1% FS per year. Every sensor is fully tested over both pressure and temperature ranges to ensure compliance with the appropriate specification. This calibration data, traceable to ISO 17025, is available.

    A wide range of electrical and pressure connections are available and ATEX zoned hazardous area types can be supplied to order. Pressure ranges from 1 to 350 barA for the 4260A, 0 to 35 barG for the 4262A and 0.1 to 10 barD for the uni-directional 4264A and ±0.1 to ±1 barD for the bi-directional 4264D. All have EMC, reverse polarity, power supply regulation and short circuit protection as standard and display exceptional linearity, hysteresis and repeatability characteristics.

    The new piezoresistive pressure sensors have been designed to withstand harsh operating conditions where extremes of temperature, vibration and shock are likely to be present. Typical applications include R&D, industrial, automotive and aerospace component and system testing.

    The CS range of enclosures are particularly suitable and ready to use within applications such as telecommunications, traffic guidance and signaling through to gas, water and electricity supply where the installed equipment is either passive or has minimal heat loss.

    This new wall-mounted enclosure completes their range of aluminium outdoor enclosures which include both wall-mounted and floor standing enclosures, each of which is available ex works as either single-walled or double-walled.

    Sampling

    Online sampling and analysis
    A necessity, not a luxury

    A major overhead for any processing plant is effluent discharge. And, in accordance with the British Water Industry Act 1991, any company having a significant quantity of trade effluent discharge must obtain consent prior to making a discharge to the public sewer network or water course. With consent granted on the basis of effluent composition and any levels exceeded resulting in major fines, the need for accurate, effective and traceable measurement has never been so apparent

    Simple sampling
    At the very least, having an on-site sampler will ensure the customer has a representative sample to give to the trade effluent officer. And here’s where Endress+Hauser can help! Their Liquiport 2000 lightweight portable sampler is ideal for an entry level sampling system. Cost-effective and reliable, its medium detection system recognises the difference between filled and empty pump hoist so that accurate dosing volumes are guaranteed.

    For more complex sampling tasks, their MCERTS approved ASP Station 2000 sampler has been specially designed for precision sampling. Offering automatic sampling initiated on the basis of time, quantity or flow, ASP Station 2000 provides defined distribution and conservation of liquid media. Samples are preserved using the integrated cooling system that keeps samples in peek condition from +2°C to +20°C (factory setting is 4°C). The current sample compartment temperature is displayed at the controls and recorded in the internal datalogger (optional) for future reference.

    Continuous monitoring
    Where continuous monitoring of online parameters is required, the CE4 measurement station with its integrated water sampler is the right choice. The system consists of four main components: electronics, analysis pipework, water sampler and accessories, meaning the system can be tailor-made to suit every measurement task – it can be configured to include pH/ORP, conductivity, DO and turbidity. All components are installed inside a weatherproof stainless steel cabinet, so outdoor storage poses no problems!

    Immediate detection
    In addition to achieving representative effluent samples, online analysis enables immediate detection of product loss. Their range of online analysers covers all key analytical parameters from pH and suspended solids through to the sum parameters of BOD, COD and TOC. And, by activating alarm set points on the analysers, you can ensure that should any content limits be breached, you’ll know about it immediately - an important factor to avoid fines. Remember, prevention is better than cure!

    Ultrapure water

    New sensor ideal for ultrapure water applications

    The Orbisphere 1100 series optical dissolved oxygen sensor from HACH LANGE is providing major advantages to international service company Serco, in the course of its work to solve corrosion problems within the British power generation sector. The instrumentation has helped reduce maintenance time and service requirements to improve the overall monitoring efficiency of testing carried out under plant conditions.

    The sensor is used to monitor feedwater for the determination of dissolved oxygen levels in ultra pure water, in this instance, primary coolant in pressurised water reactors.

    Dissolved oxygen is vitally important in applications ranging from power generation, wastewater, drinking water and beverage production to monitor and control corrosion rates of materials.

    Employing luminescent measurement technology, with no membranes or electrolyte, the solid state sensor head of the Orbisphere 1100 is unaffected by process changes or pressure shocks and requires minimal user intervention. It is quick and easy to calibrate, saving on maintenance costs as a result. Annual maintenance is limited to just a few minutes for a zero point calibration. In addition, chemicals are not required for this process, making the task easier and safer without reducing measurement precision.

    A further useful feature of the luminescent measurement technology is the elimination of effects on readings by other dissolved gases such as carbon dioxide and hydrogen.

    The Serco Technical and Assurance Services laboratory team provides a dedicated service to industry, solving corrosion related plant problems. Its research laboratories enable the simulation of most plant conditions found within the power generation market. The majority of the work performed is for regulatory purposes and for plant lifetime/safety studies, so it is vitally important that fast, accurate and reliable results are produced during corrosion experiments that replicate plant conditions.

    In order to tailor analytical services to customer needs, the laboratories employ a sophisticated range of the latest laboratory instruments.

    Chris Auener, Structural Integrity Analyst at Serco, said: “The sub 10ppb accuracy of the system within the calibration range of the Orbisphere 1100 from HACH LANGE reduces the inaccuracy of the measurement allowing previously unseen readings within primary water conditions at Serco.

    “We have numerous requirements from industry to recreate plant conditions with high purity water containing high concentrations of other dissolved gases and pH raisers and so the Orbisphere 1100 has proved ideal for our purposes. The instrument is also extremely user-friendly and meets the industry standard.”

    Another benefit of the Orbisphere 1100 is that the sensor will fit into any existing Orbisphere sensor housings, allowing quick and reliable monitoring, even at sub 5ppb levels making the instrument ideal for all power applications. The sensor is then connected to the Orbisphere 510 - Multi Channel O2, O3, CO2, N2 and H2 Gas Analyser and Orbisphere 410 - Oxygen and Ozone Gas Analyser.

    Summarising, Gareth Hughes, Industrial Process Sales Manager at HACH LANGE said: "The key feature of the Orbisphere 1100, that sets it apart from other instruments, is its ability to provide highly accurate ultra-low DO measurements with little or no service requirement, saving valuable time and costs in the process.”

    Console recorder


    Message from the PR Rep of Lonwatch which accompanied this release:
    I’ve been a PR hack for 20+ years, and I’ve NEVER used the word “breakthough” to describe a client’s product. (I admit to once using “paradigm shift” back in the 1980s, and for that I apologize).
    As you know, most products are not breakthroughs, best-in-class, state of the art, award-winning, or leading edge, except in the mind of the vendor’s PR people.
    But this time I have such a breakthrough product! The Console Recorder from Longwatch is a virtual time machine, a software package that lets companies see what the operator was watching on the HMI when the plant blew up. It records the video signal to the HMI and archives it, so companies can see exactly what happened during an alarm, explosion, plant upset, leak or any other event.
    If three monitors are available, the company can put archived plant video on one screen, display what the operator was watching on another screen, and show data from the historian on a third screen—in other words, the company can reconstruct the EXACT situation as it occurred in the control room at the time of the incident.
    I will leave it to your fertile editorial imagination to consider what this might mean in terms of legal implications, accident investigations, event reconstruction, regulatory concerns, training, operator procedures and process control/automation in general. I am with child in anticipation of reading what you might say.
    Rich Merritt


    Unique event, alarm or process upset record!
    Video software records exactly what was on HMI screens when an event occurred, archives it, and plays the video back for training or analysis purposes.

    Longwatch has launched the Operator’s Console Recorder, a software module that automatically records images being shown on multiple HMI or SCADA operator’s displays. The module takes its signals directly from each HMI screen’s video software driver, so it records the actual video being sent to the HMI. The software can accommodate video signals from an unlimited number of HMIs to show what operators were watching at the time of an event, alarm or process upset.
    Few, if any, companies have taken the simple step of making sure that their human interfaces are delivering necessary information in a timely and unambiguous fashion so that the operators make timely and appropriate command actions.
    Playing back what the operator was seeing can be a very valuable method for troubleshooting, training and process improvement. It can also be an important tool to help analyse what went wrong, or what can be done to avoid future problems.


    Video images can be combined with the automatic data mapping capability of their Video Historian, so the Console Recorder can automatically retrieve and replay operator displays simply by clicking on a time-based alarm or system message. Playing back what the operator was seeing at the time of an event can be a valuable tool for training and analysis purposes, and can help mitigate insurance and regulatory issues by eliminating guesswork and conjecture.

    Videos used for monitoring plant activities can also be combined with the operator console videos and data from a process historian. This enables engineers, analysts or investigators to see what was happening in the plant, what the operator was seeing on the HMI screen at the time, and all relevant real-time data that occurred at the time of an event.

    For example, in the case of a leak at a pumping station, investigators could watch plant video taken at a remote site showing fuel oil creeping across the floor of a pumping station, real-time data being acquired from pumps, valves and the receiving tank while the leak is occurring, what appeared on the operator’s HMI screen, and the alarm screen that came up when the leak detector went off. Investigators can then watch the operator switch the HMI screen to live video feed from the pumping station, observe the leak, and take action from the HMI to shut off the pump. Plant video would show the arrival of a maintenance crew to repair the leak. Analysis of all data and videos might show that the leak detector was poorly positioned and an alarm condition is needed for when fuel oil is being pumped but is not being received at the storage tank.

    With a typical three-display system, as found in many process control applications, it would be possible to display remote pump video on one screen, video from the operator’s display at the time of the event on a second screen, and process historian data on a third screen, thus getting a simultaneous view of what happened and what the operator saw.

    To help mitigate insurance and regulatory issues, the combined video and historian information could help determine that the operator acted correctly and the spill was cleaned up with no damage to the environment. The Longwatch Operator’s Console Recorder and Video Historian fills the gap between normal plant data acquisition and actual plant management, because it shows everything that happened during an event; i.e., what actually happened, what the data acquisition equipment monitored and recorded, and what was reported to the operator on the HMI screen.

    "Capturing the actual video feed to the operator HMI is a much better solution than traditional methods," says Steve Rubin, president of Longwatch. “Before Longwatch, recording and playback of an operator’s HMI was clumsy and limited. One method was to put a camera over the operator’s shoulder. This is intrusive and intimidating, and the camera has a limited ability to read what’s on the screen,” he explains. “In an installation with multiple HMIs, this solution would require a camera on each screen.”

    Another method is to use process historian data. “It’s possible to recreate the console display the operator should have been watching by driving it with data from the process historian,” says Rubin. “This requires the historian to record all the data values present on every display. However, no one knows which screen an operator was actually watching at the time of the event. An operator could have been looking at a trend display, not the alarm summary screen.”

    With the Longwatch system, there is no problem reading the screens, and no doubt which screens operators were watching. By combining video data from plant locations, video from HMI screens, and data from the historian, investigators can go back in time to see exactly what happened and make a better analysis of what to do about a similar situation in the future.

    PV plant control

    New versatile modular controller for solar photovoltaic plants
    Carlo Gavazzi’s new Eos-Array controller enables efficient running of PV plants to help meet the growing demand for green energy


    Carlo Gavazzi has announced a new versatile, reliable management and control system targeting small to medium or high power solar photovoltaic (PV) plants. The new controller is designed to enable the plants to meet growing demand for clean sources of energy by maintaining efficient operation, maximising performance and strengthening the Return on Investment.

    Easy to install and configure, the new Eos-Array comprises individual modular elements that, when interacting with one another, provide a complete and independent control solution that gathers accurate and dependable data to ensure effective information management. The core component is the VMU-M which performs local bus management of measuring units and I/O modules. The VMU-M assigns the proper local unit address automatically and gathers all local measurements from the VMU‑S and VMU‑P, simultaneously connecting with the external world through VMU-O modules.

    It has a modular design allowing the control to be scaled up or down according to requirements and budgets. A single master VMU-M can control 15 Eos modules on its local bus; including up to seven VMU-O I/O modules and one VMU-P unit. With no auxiliary bus wiring, the system is simple to install and straightforward to expand. Further cost saving is provided by the integrated string fuse protection and modularity also improves overall system reliability. String efficiency and inverters are controlled locally enabling operators to rapidly isolate faults, failures and inefficiencies.

    Each VMU-O provides two PV panel temperature inputs and two relay outputs to manage alarms (such as the integrated anti-theft system) and external loads (such as lighting and PV washing systems). The VMU-S measures DC output from the PV panel. VMU-P collects relevant environmental data (through external sensors) such as wind speed, air temperature and irradiation. Eos-ArraySoft can download the Eos-Array system memory to the PC, for scheduled or on-demand plant efficiency calculations and alarm analysis.

    A typical 50kW plant would use one VMU-M unit for data logging and local bus management, ten VMU-S units for string control (50kW total for 228x220W PV panels, 12.5A/400V single string), one VMU-O for I/O management and one VMU-P for environment measurements. Eos-ArraySoft software is installed in a local PC to provide data collection and historical analysis.

    Temp Calibration

    Modular concept temperature calibration systems


    The CS Series from Eurolec comprises two dry block “black body” sources for calibration with a temperature control system and a pocket for a reference thermometer. Model CS173 features a range of +30 to +200°C and model CS174 features a range of 40°C below ambient (approx. -20°C) to +85°C, together with 0.01°C resolution between -19.99°C to + 85.00°C.

    In addition, both models feature a 2 position Precision Accuracy Check (PAC*) function where at the touch of a switch, the accuracy of the unit is confirmed at 2 preset points. A calibration certificate, traceable to national standards is supplied with both models. For precision accuracy checking over an extended range, reference thermometers RT161 or PC Temp RT1 are recommended.

    These innovative units save the on the inconvenience and time lost due to external calibration, are quick and easy to use and will provide considerable cost savings when compared with external or contracted on-site temperature calibration.

    pH measurement

    Digital pH sensors
    Used in diverse markets such as automotive, electronics, building & construction, transportation and healthcare.

    A leading global supplier of engineering thermoplastic materials used in diverse markets such as automotive, electronics, building & construction, transportation and healthcare is using Memosens pH sensors in Wastewater and bio treatment facilities. These are monitored by the local Environment Protection Agency and the company carries out regular internal pH calibration checks to ensure measurement consistency and compliance with waste monitoring regulations. The company prides itself on its waste water compliance, and in order to ensure its continued efforts, they turned to Endress+Hauser for support. Its pH measuring equipment came from various sources, meaning the calibration processes and documentation were different across a range of equipment, which subsequently made operation and maintenance of instruments with different functionality more complicated for the company's technical staff.

    Memosens digital pH sensors: the reliable solution
    The aim was to achieve operation and maintenance consistency by standardising equipment. Endress+Hauser supplied its Memosens digital pH sensors, which fully equipped the wastewater monitoring andbio treatment facilities as well as the company's laboratory.
    Using revolutionary digital technology, Memosens pH transmitters allow important process data to be saved directly in the sensor, guaranteeing interference-free measuring signals and simplification of process measuring technology. And, via its inductive plug-in connection and bayonet lock, it eliminates the problems of moisture ingress, leakages and corrosion offering complete galvanic isolation.

    The real advantage that fulfilled the customer's requirements, though, is the memory chip inside the sensor head that allows calibration and sensor performance data to be stored. This facilitated the management of the calibration processes on-site and, more importantly, reduced the time needed for the calibration routines.

    Boosting calibration efficiency

    With the these digital pH sensors, the company achieves measurement integrity and optimisation of its calibration processes. The company has standardised its pH equipment with a highly functional and user-friendly system, which facilitated more efficient planning and faster calibration, so that compliance with the Environmental regulations for waste monitoring continues to be ensured.

    The customer commented: "We have a strong record of wastewater compliance and we continually look for systems that will support our Environmental Health & Safety priorities. Endress+Hauser worked with our team to provide a solution allowing us to meet our continued high standards. Since installing the Liquiline transmitters and particularly Tophit sensors, we have reduced our spares inventory and have begun a more efficient routine for calibrating all pH systems associated with our wastewater plant. Our technicians have reported that being able to pre-calibrate the sensors in our workshop, before installing them in the plant, has made the process of multiple calibrations far quicker and easier. On site we have five transmitters installed in our process, two in our lab and one in our workshop for calibration purposes. To date, there have been no reliability issues after 18 months of constant use."
