HMI & SCADA distributor in Singapore

InduSoft adds a new distributor to its list of InduSoft Web Studio HMI and SCADA software distributors in the Middle East and Asia. Among the hundreds of international distributors for InduSoft Web Studio, AKOE TECH in Singapore will offer an additional foundation in a region where InduSoft Web Studio is expecting rapid expansion in the near future.

AKOE TECH is a HMI/SCADA software distributor located in Singapore, and serving the Asian market. Mr. Edward Chan of AKOE TECH had the following to say in regard to becoming a new IWS distributor. "Our focus now is to secure new projects with our existing customers so that there is a project reference for Indusoft Web Studio. We want to provide excellent support through familiarity and knowledge of InduSoft Web Studio products."

InduSoft is continuously adding to its range of distributors, certified system integrators, and original equipment manufacturers. (OEMs).

Two-wire GWR

Released in 1998, The Magnetrol International NV Eclipse® Model 705 was the first two wire guided wave radar (GWR) on the market. Thirteen years later, this high quality GWR device is still fluently finding its way to highly critical applications.

The Eclipse® 705 is type approved for steam drums, EN 12952-11 (water tube boilers) and EN 12953-9 (shell type boilers) as “primary safety” and “secondary safety”. Combined with a 7MS probe the device can be used in saturated steam applications at a pressure of 155 bar at an equivalent temperature of 345°C.

Additional diagnostic tools allow the user to integrate this transmitter into highly demanding safety instrument loops. With a Safe Failure Fraction (SFF) of 91% the device scores amongst the highest – if not the highest – safety levels.

It is possible to install two or even three Eclipse® devices on one external cage for specific applications. Even when installing only two devices in one cage a SIL3 safety level can be obtained. Adding a third device to the same cage assures continuity to the production process. The three obtained individual level signals increase the overall reliability.

A typical example for such an extreme safety application can be found in the power generation sector where accurate monitoring of water levels in steam drum and boilers is a must. It is a challenge maintaining constant liquid level in the upper part of the drum in order to provide the proper quality of steam. Instrumentation must withstand high temperatures and pressures.

Network-based control system enhanced

Yokogawa enhances network-based control system by releasing new modules for power and upstream oil and gas applications

 Yokogawa Electric Corporation has released a number of new modules for the STARDOM™ network-based control system. The new modules include control modules with the high speed and reliability required for small- to medium-size turbomachinery, a frequency input module that can accurately measure the speed of even slowly rotating wind turbine blades, and an upgraded CPU module for oil and gas upstream processes that features improved reliability and greater memory capacity.

Development background
Recently, energy markets have been booming in developing countries. One of the reasons for this is the rising demand for electricity spurred by economic growth. As a result, there is a need for power generation facilities that can be constructed within a short timeframe. Demand for the steam turbines, hydro turbines, compressors, and other small- to medium-size turbomachinery installed in these facilities is also rising. This type of machinery is also used in renewable energy facilities such as biomass and micro-hydro plants, and in conventional oil and gas fired power plants. At the same time, the number of wind power generation installations is also increasing in emerging countries.

To satisfy these needs, Yokogawa has augmented its module lineup for STARDOM field control node (FCN) autonomous controllers by developing new modules for small- to medium-size turbomachinery and wind power generation applications. For the conventional energy market, Yokogawa also has improved the reliability and functionality of the FCN-RTU low-power autonomous controller that was developed for the control of oil and gas wellheads distributed over a wide area.

Capitalising on the enhanced functionality available with these modules, Yokogawa will expand its business in the energy industry.

Product features
1. Optimised for power industry applications
The newly developed control modules include a servo module that controls the rotational speed of small- to medium-size turbomachinery and a high-speed protection module that protects machines by detecting anomalies such as excessive rotation speeds.

The frequency input module measures rotational speeds with high accuracy (±0.1% of reading). This is true even at speeds as low as 0.1 Hz, ensuring that wind turbines can operate smoothly in all conditions, from strong winds to gentle breezes.


2. Enhanced functionality for oil and gas upstream processes
Customers in the oil and gas industries are working hard to improve maintenance efficiency for remote wells. To support them, Yokogawa has enhanced the CPU module for the FCN-RTU controller to ensure best-in-class reliability. Specifically, the module now has the same error check and correct (ECC) memory found in high-end PCs and the memory capacity has been doubled to facilitate the long-term storage of gas volume data and other on-site information.

Yokogawa has also enhanced its DNP3 software to comply with the latest DNP specifications and cover a wider range of SCADA applications.

3. Support for Windows®7
The VDS monitoring and controlling software (SCADA software) and other software for the STARDOM platform now support Windows®7, thus ensuring that engineering, operation, and monitoring can all be performed under the latest operating system.

Award for Hungarian plant

HART Communication Foundation Executive Director Ron Helson (2nd from left) presents the 2010 HART Plant of the Year Award to MOL Danube Refinery, Százhalombatta, Hungary, (l-r) László Galambos, Refining Director; Gábor Bereznai, Head of Instrumentation and Electrical Department; Gergely Nádasy, Head of Maintenance Management; and József Bartók, Automation Engineer.
The HART® Communication Foundation  has selected the MOL Plc Danube Refinery located in Százhalombatta, Hungary, as recipient of the 2010 HART Plant of the Year Award. The award showcases end users who have demonstrated creativity in the application of HART Communication.

Beginning in 2002, MOL engineers made the strategic decision to install HART-enabled devices throughout their operation and to utilize all the benefits of HART Communication, both wired and wireless, in the broadest possible scope. This decision was part of a plant-wide refining maintenance strategy with an objective to increase operational reliability.

“We made the decision going forward to purchase intelligent field instruments that support the HART Protocol and then to develop and use the in-depth and sophisticated communication options embedded in those HART instruments,” says Gábor Bereznai, MOL Instrumentation and Electrical Department head. “Our directive became ‘let’s get connected—off-line and on-line—and put these HART instruments to work’.”

Connecting HART-enabled devices into an on-line diagnostics system has changed the way the MOL maintenance department runs its operation. On-line device diagnostics — instrument signals going directly to the plant maintenance and control systems—makes it possible to prevent unplanned shutdowns and plant slow-downs by allowing engineers to detect and resolve automation asset problems before they become critical.

According to MOL maintenance engineers, since the introduction of HART diagnostics at the petrol refinery, the number of valves selected for repair during a planned shutdown has dropped from 60% to about 5%. The system works so well and has proved to be so beneficial, that the company has set up a separate unit of three people to operate the applications and systems. Using HART diagnostics has resulted in MOL saving an estimated $2 million USD in reduced maintenance costs and avoided unscheduled shutdowns.

“On-line diagnostics provided by the HART instruments does something more than preventive maintenance,”
says József Bartók, automation engineer at MOL Danube Refinery. “It ensures the stable operation of the system and increases the precision of control. This is an aspect of the technology that comes directly to the bottom line, increasing the profit generating capability of the unit.”

More than 30,000 of the plant’s 50,000 instruments are HART-enabled with 3,700 of these HART devices—mostly control valves and instruments used in critical control loops—connected directly into computerized maintenance management systems.

ARC Advisory Group Research Director Wil Chin says, “ARC congratulates the MOL Danube refinery for taking HART Communication to the performance levels inherent in the technology. With only a minority of installed HART field devices connected to automation or asset management systems, organizations should apply lessons learned and deploy initiatives to unlock valuable information embedded in their smart devices.”

Inductive sensor

Eaton’s Electrical Sector is launching a new iProx inductive sensor series that embodies both power and versatility. Thanks to an integrated microprocessor and the unique Smart SenseTM technology, each iProx sensor has a large detection range and intelligence that can be adapted to each application. Cylindrical devices with switching distances of up to 29 millimeters are available, twice the switching distance of other inductive sensors of the same size.

Greater versatility connectors

Harting has extended the versatility of its innovative Han-Yellock® connector family by introducing a new version - Han-Yellock® 60 - with a larger housing that enables up to six connector modules to be incorporated.

The new Han-Yellock® 60 retains all the key features of the initial Han-Yellock® concept, including the internal latched locking mechanism on the connector hood, a wide range of Han-Yellock® modules to offer a large number of potential configurations, an adaptor frame for use with modules in Harting's Han-Modular® series, insulators that can snap into the front or back walls of the housing, and a protected earth (PE) contact in crimp or Quick Lock termination

The new housing size 60 has been designed to offer an optimum balance between size and functionality. The installation dimensions give a compact profile in machines and switch cabinets, while a choice of function-oriented cable outlet angles ensures ease of handling and assembly in densely packed connector panels. The Han-Yellock® housings also protect the interface against unintentional or unauthorised opening. Mating and locking are carried out in a single step.

Covers protect the connector against moisture and dirt when it is not inserted, and contribute to the longevity of the connection. A further key design feature is the way in which the protective covers can be snapped in place on both sides of the housing. Customers can choose the direction of the cover swivel area, allowing adaptation to the individual application during the planning or retro-fitting stage.

Inserts from the established Harting Han-Modular® Series can be snapped into place in all Han-Yellock® housings without tools by using an adaptor frame. This process can be carried out on the insertion or termination side, which simplifies work sequences during commissioning and cabling work. The adaptor frame allows a broad spectrum of signal and power transmission modules to be integrated into the connector, including devices for electrical, electronic, fibre-optic and pneumatic interfacing.

Fail-safe force measurement

DABU/I AD2T Bridge Amplifier for Exact Force Measuring Chains
With the bridge amplifier DABU/I AD2T, Baumer offers a fail-safe force measuring amplifier for use in challenging industrial environments. The bridge amplifier has an analogue signal path and converts mV/V signals from bridge circuits with strain gauges into a voltage or current (version DABU/DABI) signal. Depending on the type of product, a 2x¼ bridge or a full bridge can be connected to the input of the amplifier. The DABU/I AD2T boasts a bandwidth of 1000 Hz and an excellent signal-to-noise ratio. Its wide tare level of ± 6 mV/V allows for safe and easy implementation of the measuring chain even under difficult assembly conditions. The tare function can be triggered by a control pulse and only takes 5 ms to complete its operation. The amplifier has an input signal range from 0.25…2 mv/V.

The small, rugged aluminium housing of the unit complies with protection class IP65. As the amplifier does not contain any mechanical parts, it is highly resistant to vibration, which makes it particularly suitable for use in industrial applications. Electromagnetic compatibility has been tested according to the European norm EN 61000.

The DABU/I is suitable for static and cyclical measurements. It was designed to complement measuring chains with any force and strain sensors by Baumer, including the DLRx load cell, DSRC strain ring, and DLRP strain sensor. Thus, the DABU/I AD2T supports Baumer’s patented STRAIN-MATE principle, which makes it possible to measure clamping forces with strain rings, but without the time-consuming procedure of bonding strain gauges onto the surface.

Depending on the respective configurations, the DABU/I is available with different levels of amplification. For full bridges, available versions include 0.25 mV/V, 0.50 mV/V, 1.00 mV/V, and 2.00 mV/V. For 2x¼ bridges, options include 250 με, 350 με , 500 με, and 1000 με

Loop splitter/retransmitter

QLS Quad Loop Splitter splits one 4-20 mA loop into four independent loops 

Laurel Electronics' Model QLS is a quad output 4-20 mA loop splitter and retransmitter with ±10V common mode isolation between inputs and outputs.

Problems occur when the same 4-20 mA signal from a transmitter needs to be sent to multiple devices, such as meters, recorders and PLCs. If the devices are in series in the same loop, they cannot share a common ground, but must be electrically floating. This is often not possible. When any device in the loop is removed, fails or if a wiring fault occurs, all other devices in the loop also loose their 4-20 mA signal. The transmitter voltage compliance limit may be exceeded, since the voltage drops across loads in series are additive. Also, the 4-20 mA signal to each device cannot be individually adjusted for calibration purposes.

Model QLS solves these problems by sourcing up to four (4) independently adjustable 4-20 mA outputs from a single input. The outputs can share a common ground. The input and outputs are mutually isolated to ±10V by means of active circuitry to accommodate differences in local grounds with normal industrial grounding practices. If any device in an output loop is removed from a loop or fails, or if a wiring fault occurs, the other loops continue to operate properly. Each loop only drives a single load, avoiding compliance problems. The input to the quad loop splitter can be 4-20 mA, 1-5V, 0-5V or 0-10V, as selected by jumpers. An excitation output is provided on the signal input side to a drive a 2- or 3-wire transmitter at 24 Vdc and up to 30 mA.

Each output loop has two potentiometers for ±10% fine adjustment of zero and span, a yellow LED lamp to indicate loop continuity, and a test point across a 10-ohm series resistor, where 200 mV corresponds to 20 mA. This allows a multimeter to be used to measure the loop current without breaking the loop.

Control performance monitoring

PlantTriage Diagnostics automatically initiate work orders

ExperTunes PlantTriage can now share information with maintenance planning and other enterprise resource planning (ERP) tools. PlantTriages diagnostics can be used to initiate work requests for instrument repairs, control tuning, and valve replacements.

Proven in hundreds of plants worldwide, the PlantTriage control performance monitoring system automatically diagnoses and prioritizes process, control, and instrumentation problems, 24 hours a day.  Integrated analysis and tuning tools improve plant results by focusing effort on the most critical issues.

PlantTriage contains tremendous knowledge of the process and the equipment.  Now, users can fully integrate that knowledge into their ERP system workflow. says George Buckbee, ExperTunes Vice President of Product Development.

The new integration tools can be applied to any of the 20 Problem-Solver reports that come with PlantTriage.  Beyond that, users can design custom reports to pass any set of PlantTriage information, directly from a web browser interface.  A flexible XML intermediary language enables users to further customize the information being passed.  This new approach complements the existing capability to share data via OPC, e-mail, and export to Microsoft Excel and Word.


John Gerry, President of ExperTune, adds, One key to delivering bottom-line results is to use control performance data in the daily workflow at each plant.  These tools streamline the workflow process, accelerating the pace of improvement.

The new tools are included in the version 10 release of ExperTunes PlantTriage software.

Tree safety

Technology transfer tests tree safety

Highway engineers and horticulturalists have adapted the latest in helicopter technology to solve a critical safety problem in their own industries, tree viability.

Trees can transform a roadside verge, townscape or recreation space with their beauty and their ability to capture carbon dioxide.  But they also present a potential hazard: if they fall, they could block a vital highway or even kill someone.

As a result, professionals responsible for trees like to test the strength of their roots, usually by fixing a sling around the trunk and giving it a good tug with a tractor!

“This procedure lacks some finesse,” says Tony Ingham of Sensor Technology, who has been working on ways to improve the technique.

“The basic idea is to put a strain gauge in line with the sling, then convert the readout from Newtons to a wind speed equivalent. This is perfectly achievable, but the concept needs refining to make it attractive enough to become widely adopted.”

The tractor crews will not want to spend time setting up instruments, taking readings, recording them and then set about making complex calculations. If they can’t rope up a tree, give it a pull and move onto the next one in a matter of minutes, they won’t be interested.

Sensor Technology realised that they had the solution to this with their LoadSense range.  Tony Ingham continues: “This is actually an intelligent cargo hook for helicopter pilots who need to underslung carry loads. This may seem like a different world, but the concept is that the hook has on-board electronics for measuring the load and a wireless transmitter for sending the live data to a nearby ruggedised PC or custom built handheld readout.

We replaced the hook with one more suited to the tree work, recalibrated the strain gauge and wrote some software appropriate to the job in hand. The procedure with our equipment is to pull the tree until the first suggestions of movement, with the load force being automatically displayed as wind speed and a pass/fail signal.”


In the second stage of calculation, the software can use a look-up table to suggest how often such as wind is likely to be experienced. Tony says that for a future development Sensor Technology is talking to the Met Office about using their wind maps of the UK along with GPS (global positioning system) readings to produce results almost to the individual tree:

“All the data handling and calculations are transparent to the crew, they get simple pass/fail reading. But the data can be stored and further resolved into high level management information which will help with developing long-term maintenance programmes.”

Crack movement

Monitoring movement of cracks in structures with LVDTs

Measuring the changes in the width of cracks that occur in civil structures and buildings can be accurately determined by the use of Linear Variable Displacement Transducers (LVDTs). This important diagnostic technique can provide data to help understand the cause and then action appropriate remedial work where needed.

Transducer solutions specialists RDP Electronics offer a comprehensive range of LVDTs including waterproof options for use in external applications and harsh environments. Using analogue versions with a 4-20mA facility permits the use of long cable runs which can prove a useful capability where location of monitoring equipment is remote from the crack location.

The first 78 GHz radar level transmitter for solids level measurement

Siemens Industry Automation Division has launched Sitrans LR560, the first radar level transmitter operating at 78 GHz frequency.
The Siemens Industry Automation Division launches the first radar level transmitter
with a frequency of 78 GHz. The device is equipped with a newly developed lens
antenna and uses the non-contacting FMCW technology.
Sitrans LR560 is a non-contacting 2-wire FMCW (Frequency Modulated Continuous Wave) radar level measurement transmitter with a measurement range of 100 meters (328 ft). The transmitter emits a narrow four degree beam which avoids silo wall obstructions and other installation interferences, allowing it to be installed practically anywhere on the top of the silo. As the first radar transmitter to operate at 78 GHz frequency, it emits a short wavelength to provide exceptional signal reflection even from solids with a steep angle of repose. The graphical Quick Start Wizard guides the user to get Sitrans LR560 operational in minutes for accurate and reliable level measurement readings without any additional fine-tuning.

Sitrans LR560 is available with HART®, PROFIBUS PA, or FOUNDATION™ Fieldbus protocol. Programming is supported locally with pushbuttons or with an infrared handheld programmer. The transmitter also supports remote configuration and diagnostics with Siemens Simatic PDM (Process Device Manager), Emerson AMS™, or PACTware™ using Siemens DTM. The local display interface features a backlit display and can be rotated to four positions for convenience. The unique lens antenna is highly resistant to material build-up and an integrated purge connection is included for cleaning exceptionally sticky solids material. The high frequency operation makes aiming unnecessary, but the optional aiming flange helps direct the beam to an area of specific interest, such as the discharge area of the silo cone.

Low power industrial radio transceiver modem

LPRS introduce industrial-use DSSS true diversity radio transceiver modem for applications in the U.S.A.

LPRS has introduced the Circuit Design MU-D1-R 915 MHz, embedded low power radio transceiver modem for industrial use that complies with U.S. FCC Part 15.247.

The MU-D1-R operates in the U.S. ISM band frequencies (902 to 928MHz) and is designed to be embedded in wireless connected systems. This radio modem was developed for industrial applications that require stable and reliable operation. It features low power consumption and can achieve line of sight radio communication beyond 300m with battery operation.

In addition to using highly noise-resistant direct-sequence spread spectrum (DSSS) modulation, the modem has a true diversity receiver function with two receiver circuits for preventing signal dropout due to multi-path fading. This ensures highly stable and reliable radio communication in the congested 902 to 928 MHz ISM band which is used by many types of wireless controlled equipment.

With 20 frequency channels available it can be used in many wireless systems. The modem operates at low power, 55mA/8mW when transmitting and 58mA when receiving and with its small size, 36 x 26 x 8mm it can be built into units that require battery operation.

John Sharples, Managing Director of LPRS comments: "The new MU-D1-R transceiver from Circuit Design is a highly reliable, industrial use modem. Using direct sequence spread spectrum for superior noise resistance instead of simple antenna switching type diversity, the modem uses a true diversity receiver circuit with two built-in receiver circuits.”

In addition to the CDP series transmitter and receiver modules and STD/LMD series transceiver modules which are highly regarded in the European and Japanese markets, Circuit Design offers the MU-D1-R series radio modem with a built-in wireless protocol to enable the input/output of data with simple commands. With its built-in CPU, the MU series performs wireless-specific high frequency control for UART communication with an external microcomputer. As a result system development times are significantly shortened and component numbers reduced. In addition, the built-in protocols make networking simple for applications that require reliability and real time control such as industrial remote control. The MU-D1-R is expected to be used in a wide range of low power industrial applications such as monitoring systems where battery operation is required.

Key features of the MU-D1-R include a wide operating temperature range of -20 to +65ºC, built in TCXO and all high frequency circuits are enclosed inside the shielded case. Operating voltage is 4 – 5.5 VDC with low power operation enabling systems to run for long periods from battery power. Compliant with FCC Part 15.247, frequency range 905.5 to 924.5 MHz, 20 channels, output switchable between 8 and 40mW, data rate 40 kbps (interface), 600 kbps (wireless 40 kbps x 15 chips), size 36 × 26 × 8 m and weight 13g
