New type of probe measures current in PCB tracks directly

Aim-TTi has launched an entirely new type of current probe which is cable of measuring currents in PCB tracks.

The Aim I-prober 520 positional current probe uses a patented technology to observe and measure current without the need to break or surround the conductor.

Measurement of current normally requires either the insertion of a shunt resistor, or for the conductor to be passed through a closed magnetic loop. Typically this is done using some form of split clamp device. Whereas this is suitable for individual wires, it is of no use for measuring current in PCB tracks.

The I-prober 520 is a compact hand-held probe which is used with an oscilloscope. By placing the insulated tip of the probe onto a PCB track, the current flowing in the track can be observed and measured.

The probe has a bandwidth of DC to 5 MHz and a dynamic range of 10 mA to 20 A peak to peak. It is safety rated to 300 V Cat II (600 V Cat I) and is suitable for connection to any oscilloscope.

The Aim I-prober 520 operates by sensing the field in very close proximity to the track. To achieve a calibrated measurement, the field sensor must be capable of maintaining a precise distance from the track. To achieve good sensitivity this distance must be very small because field reduces with the square of distance (to a first-order approximation).

To create a practical current measurement probe, a very special type of miniaturised sensor was needed. The requirements included very small size with precision dimensions, DC sensing capability, wide AC bandwidth, and low noise. None of the existing sensor technologies used within field and current probes was suitable for this.

Instead, the I-prober 520 uses a patented miniaturised version of a fluxgate magnetometer, developed in conjunction with Cambridge University. It is the patented miniaturisation that enables it to measure the field at a precise point in space. In addition, the miniature sensor has much lower noise and much wider bandwidth than a conventional fluxgate magnetometer.

As well as measuring currents in PCB tracks, the probe can be used on component leads or any other current-carrying conductor. An interesting example occurs in ground planes, where it can be used to observe circulating currents, interference injection points and “hot spots” in order to optimise design.

The Aim I-prober 520 is supplied with a control box and calibrator, power supply, and a clip-on toroid assembly which can convert it into a convention closed magnetic loop current probe.

Static earthing

The newly upgraded Earth-Rite TELLUS II from Newson Gale offers effective static earth verification for drums, IBCs and other mobile equipment in hazardous area operations. The lightweight static dissipative polyester (SDP) enclosure can be mounted in all industrial flammable or combustible atmospheres and provides the operator with a reassuring bright green flashing LED to confirm a positive connection to earth, as well as a pair of output contacts for interlock with pumps, valves or other control or alarm devices.

The Earth-Rite® TELLUS constantly monitors hazardous area processing operations involving the handling, transporting or mixing of flammable or combustible products, whether they be powders or liquids. Operating in real time, the system confirms that a positive connection to earth exists and, most importantly, remains intact for the duration of the operation. As long as the resistance of the connection to a designated earth exists and remains below 10 ohms a bright green pulsing LED display inside the hazardous area assures the operator of safe conditions, preventing dangerous static electricity accumulation on the monitored object.

Newson Gale selected 10 Ohms as the monitoring threshold for the pass/fail condition as this conforms to all major international industrial static control technical standards and guidelines. The system very accurately monitors to this low resistance and switches from permissive to non permissive whenever the resistance to the earthing point rises above 10 Ohms, or is lost completely. An additional interlock mode (pair of changeover contacts) can provide an extra margin of safety by sounding an audio alarm or initiating an automatic safe shut-down procedure should the earth connection be lost. The Intrinsically Safe Earth-Rite TELLUS Indicator/Junction Box is made from lightweight SDP and is easy to install and observe close to the point of use – for example on drum filling or mixing machines.

The Earth-Rite TELLUS Static Earthing System consists of a power supply unit and controller which is mounted in a safe area as much as 500 metres / 1,600 feet from the hazardous area and, within the hazardous area, the intrinsically safe earth-connection status-indicator with a two-pole earthing clamp on retractable connection cables in various length options. Both the PSU/Controller and Indicator/Junction Box are waterproof and dust-tight (IP66 / Nema 4X). Alternative connections, such as plugs and sockets, are also available. The system operates on 110V – 230V AC (user selectable) 50/60Hz supply, with certified Intrinsically Safe (I.S.) monitoring circuit output for connection in the hazardous area. 

The Earth-Rite TELLUS enables compliance with the best practice guidelines of NFPA 77 and CENELEC TR 50404 for controlling static electricity. All TELLUS monitoring systems are approved for safe use in Hazardous Areas to ATEX “Ex” European/IECEX standards and US and Canadian standards (Class/Division or Class/Zone) for all gas, vapour or dust operating environments. In addition to its hazardous area approvals, the system achieves a SIL 2 Functional Safety rating according to IEC 61508 and has an operational temperature range of -20 to +60 deg C.
For over 25 years, Newson Gale has been supplying the chemical and processing industries worldwide with its market leading range of static control products to help ensure people, plant and processes are protected from static caused fires and explosions. The Earth-Rite TELLUS forms just part of the range of static earthing and bonding equipment available from the Nottingham UK based company.

Connecting devices to BACnet

HMS Industrial Networks now releases Anybus® CompactCom™ for BACnet/IP – a network communication module which can be embedded into air conditioning equipment, pumps, ventilation devices etc. in order to enable communication with the BACnet/IP network.

With this new member of the Anybus CompactCom family, HMS offers ready-made connectivity to BACnet/IP – an up-and-coming network in the building automation and HVAC (Heating Ventilation AirConditioning) industry. By choosing Anybus CompactCom for BACnet/IP connectivity, device manufacturers can save up to 70% of the development costs compared to developing a BACnet/IP communication interface in-house.

“As with many other industries, the building automation and HVAC industry is now contemplating a migration towards Industrial Ethernet technology and BACnet/IP could very well be the next big thing within this industry,” comments Leif Malmberg, HMS Product Line Manager, Embedded Solutions. “By implementing Anybus CompactCom, device manufacturers can also achieve instant connectivity to 19 other industrial networks by simply switching Anybus module. This opens new business opportunities for the device manufacturers and widens their market considerably.”

2-port switch makes devices easier to network
The Anybus CompactCom BACnet/IP includes an integrated 2-port switch that makes it possible to connect the device to the network in normal fieldbus style (daisy chain) rather than connecting all devices through an external switch. This is a demand from many end users today.

Technical highlights
The Anybus CompactCom module acts as a server (B-ASC) on the BACnet/IP network. It is available with and without housing and is about the size of a compact flash card.
Thanks to the integrated web functions (such as dynamic web pages, email and FTP) it is possible to get online statistics, notification emails and other information about the device that the Anybus module is embedded into. For example, it is possible to get an email whenever the device is in need of service.
The onboard 2-port switch provides two 100 Mbit/s full duplex Ethernet interfaces with RJ45 connectors.

Wireless to automate tank storage level monitoring

"We don’t see any reason or benefit to using cables!" says storage site manager.

FH Tank Storage  is using Emerson Process Management’s Rosemount® wireless level and pressure transmitters to provide overspill protection at its Kalmar storage terminal on the east coast of Sweden. 
FH Tank Storage AB


They have installed a plant-wide Smart Wireless network, DeltaV digital automation system, and AMS Suite predictive maintenance software to automate tank storage level monitoring. This enables FH Tank Storage to meet the latest environmental and safety requirements, as well as improve the efficiency, accuracy and reliability of level monitoring and the safety of terminal personnel.
 
This Smart Wireless network has enabled measurement data to be processed without the need to install new cabling, a cost saving of between €50,000 - €100,000. New cabling would require extensive groundwork which would disrupt operations and fuel tanker traffic around the site.

The Rosemount transmitters are deployed on the storage tanks and transmit measurement data to Emerson’s DeltaV system installed in the main control room. AMS Suite helps operators monitor the health of both the wireless network and the individual transmitters, and improves the efficiency of maintenance staff by identifying any faults and reducing the number of trips into the field.

“Emerson’s Rosemount level, pressure and temperature transmitters, and the Smart Wireless network, have enabled us to implement a cost-effective automated measurement system,” said Lars Ferm, Site Manager, FH Tank Storage. “They have also improved the monitoring of tank levels and have provided a fully approved overspill protection solution.”

The FH Tank Storage terminal has a capacity of approximately 13,000m3. The 68 tanks, ranging in size from 10m3 up to 2100m3, are used to store solvents, petrol and a range of chemicals. Increasingly tight environmental regulations required overspill protection to be added to all existing tanks, with new level switches needed to trigger an alarm should levels rise above preset levels. 

Previously, tank level measurements were performed manually. This required operators to climb to the top of tanks in challenging winter conditions, putting them at risk of injury. The monthly checks took a whole day and involved the use of dipping ropes, calculating volumes, and updating a white board in the main control room. Although a rigid set of procedures was in place to ensure accuracy and reliability of measurements, FH Tank Storage wanted to automate these measurements to reduce risk and remove any potential human error when recording, calculating and listing tank levels.

Emerson proposed the implementation of a continuous automated measurement solution using the PlantWeb digital architecture and Smart Wireless technology to transmit accurate and up to date tank level measurements that could also be used to provide overspill protection. Rosemount devices deployed on 29 tanks transmit level and temperature data back to the latest versions of the DeltaV system and AMS Suite software installed in the main control room. A large screen provides operators with visualization of all the tanks, tank levels and any high level alarms or instrumentation failures. The solution was presented to and accepted by Länsstyrelsen, the Swedish local environment and safety authority. 

FH Tank Storage wanted to minimize the different types of devices installed, to enable easier maintenance and reduced inventory. For the smaller tanks, FH Tank Storage installed Emerson’s Rosemount 3051S wireless DP pressure transmitters. The pressure measurement of the liquid's mass and the media's density is used to derive level. The devices transmit data every minute.
A number of the larger tanks have floating roofs, making it more difficult to install DP pressure transmitters, so Emerson’s Rosemount 5402 non contacting radar level transmitters have been deployed on the larger sized tanks. Emerson’s Smart Wireless THUM Adapters are connected to each of the radar devices to transmit the data via the wireless network. The Rosemount 5402 was selected because it is suitable for almost all tank sizes, is unaffected by floating roofs, and is suitable for a broad range of liquids and gases. Measurement accuracy is not affected by dirty or corrosive liquids or by fluid properties such as density and viscosity. 

 “The Smart Wireless network was relatively simple to install and both the network and the transmitters have been extremely reliable since they were installed,” explained Ferm. We expect to continue to deploy wireless level devices in the near future as we don’t see any reason or benefit to using cables.”

There have been no overfill alarms at the site so far, and the historical information provided by the radar measurements has enabled quick and accurate answers to customer queries. Based on this success, FH Tank Storage has placed a further order for Rosemount radar level transmitters and THUM Adapters to automate 15 more tanks. In addition, 5 tanks are currently being constructed at the terminal and Rosemount radar devices are expected to provide the level measurements and overspill protection.

VOC emissions data may be invalid!

Keith Golding, MD of Quantitech, is urging stack testers and the managers of prescribed industrial processes to check the MCERTS certificates of their Flame Ionisation Detectors (FIDs). He says, “The FID fuel gas for which the certificate is valid is now specified so process operators should ensure, for example, that if the certificate specifies a Hydrogen/Helium mix, any compliance monitoring must also use this mixture or results will be invalid.
 

“Users of the Sick Bernath 3006 need not be concerned because the MCERTS field test was conducted with both fuel gas options – Hydrogen and Hydrogen/Helium mix. However, Hydrogen is by far the more preferable option.”

The fuel gas for FIDs is an important issue because H2/He gas is at least three times the cost of Hydrogen gas, so one might assume that all FIDs would run on Hydrogen. However, some FID manufacturers are unable to achieve the MCERTS performance requirements whilst running on Hydrogen and have to resort to the more expensive H2/He mixture.

This situation is exacerbated by the high fuel gas flow rates (up to 180cc/min) that are required by some FIDs. In contrast, the market leading Sick Bernath 3006 portable FID has an MCERTS certificate to confirm high performance levels using Hydrogen gas at very low flow rates (20cc/min).

Explaining the significance of the fuel gas, Keith Golding says, “The use of this expensive gas mixture at high flow rates means that fuel costs can be an astonishing 27 times greater. However, the cost of the fuel gas is not the only significant issue; high flow rates necessitate a large supply of gas which can create logistical problems and health and safety issues when transporting large bottles in the field.


“Typically the 3006 is able to operate for a full working week from one small 1 litre bottle of Hydrogen, so the MCERTS approved ability of this instrument to run on Hydrogen at very low flow rates is a major advantage to process operators and stack testers.”

Software improves production efficiency and quality

EETechnologies recently completed a full implementation of Aegis’ Manufacturing Operations Software (MOS). This was effective in fulfilling their strategy to improve efficiencies and quality by streamlining and controlling process planning and launch, process tracking and control, and quality and test management. “Speed, control and visibility are core to competitiveness. We utilize technology to connect data to all of our factory processes for our customers’ benefit”, commented Sonny Newman, President of EE Technologies.<

Aegis MOS provides the tools needed by production staff to translate engineering designs into manufacturing documentation. Aegis provides support for virtually every CAD type and simplifies programming of the machines that use the CAD data. It allows EET to automate their revision control processes; it also automates the distribution of information to operator workstations in sufficient detail for quality product building. All of this is achieved with a system which, being paperless, achieves an EET environmental corporate objective.

During manufacturing, materials are related to individual machines and stations at the point-of-use and are electronically validated against job parameters. As units travel through each station, their correct, validated material setup is guaranteed, and each unit then automatically inherits the currently loaded material set. This ensures that the right product is at the right station at the right time for the right job, and provides EET’s customers with total traceability.

Users can now determine where any work order is located throughout the factory in real-time. Customer service often depends on delivering the information they need when they need it. Aegis allows EET to track WIP status and provide predictive job completion times. This is important to EET’s customers.

Quality has to be built into any manufacturing process. The Aegis software collects data in real time, providing EET with the information necessary to build the product correctly, verify its quality during production and facilitate corrective actions. This data is also available for reports, visualizations, and real-time dashboards that can be configured and used by EET to constantly improve quality and efficiency. Traceability of every product is also achieved; this allows failures and rejections to be tracked down and eliminated before they become an issue for the customer.

EET’s Director of Operations, Clay McElhany, summarizes Aegis MOS’s benefits: “Investing in technology is just one of the ways we provide world class service to our customers. With Aegis, we have instant visibility of the process and product. We continually improve our processes to be more efficient and provide our customers with the best quality, delivery, and costs.”

Safe 2 wire Coriolis flowmeter - a first!

Coriolis flowmeter achieves superior performance and safety without the need for external adapters or barriers

The Promass E 200 Coriolis flowmeter, from Endress+Hauser, is the world’s first Coriolis flowmeter with true two-wire 4-20mA HART technology. The Promass E 200 is the only two-wire Coriolis meter with a full 16 mA of measurement span without the need for excess adapters, power supplies or barriers.

This advanced meter design results in simplified integration into existing control systems, and allows the flowmeter to be used with DCS, PAS, PLC and other remotely operated controller systems. The 4-20mA interface makes it easy to replace legacy flow sensors without any change in field wiring. In many cases, the Promass E 200 can simply be “dropped in” to replace an existing flowmeter, without the need for additional hardware or rescaling of control systems.

"The Promass E 200 is the world’s safest Coriolis meter because its two-wire technology enables it to be used in intrinsically safe applications for Class 1 Division 1 locations. The Promass E200 has been submitted for a SIL-2 rating for critical applications and complies with NE43 (NAMUR) safety standards, including operating down to 3.6 mA in a fail-safe condition. Self-monitoring and error diagnostics are standard features that are designed in strict accordance with the specifications of NE107 (NAMUR)."

It has built-in diagnostics, and displays clear text errors and root causes on its local display in case of a fault. The flowmeter can also be commissioned and diagnosed with Endress+Hauser’s FieldCare software.  If servicing is needed, the HistoROM function automatic data backup function ensures automatic reconfiguration of a repaired or new meter without the need for recalibration.

This unit simultaneously measures mass flow, fluid density and temperature. In addition to liquids such as acids, alkalis, and solvents, it also measures most gases. It measures mass flow and volume flow with 0.25% accuracy, and measures density with accuracy of 0.0005 g/cm3. It operates in process pressures of Classes 150 to 600, and process temperatures up to  284 °F.

The Promass sensor is highly immune to external disturbances such as pipeline vibration, and is stable under changing process conditions such as pressure, density, temperature or viscosity.

They can supply this instrument in line sizes of 3/8 to 2 inches (DIN 8 to 50) with 904L Stainless Steel as a standard wetted material. Transmitter options include aluminium and stainless steels to meet various chemical, oil, gas, process, food, beverage and life sciences applications.
