Yokogawa releases a scalable SensTation pH/ORP Measurement Solution

Yokogawa SensTation pH-ORP.jpgYokogawa Electric Corporation announces the release on this date of the SensTation pH/ORP measurement system, a scalable and integrated solution that combines the unique capabilities of the SENCOM pH/ORP sensors and the SMARTDAC+ data acquisition and control system. This solution eliminates the need for a pH/ORP transmitter and allows users the choice of any of the paperless recorders in the SMARTDAC+ series, each of which can connect to up to 16 sensors. In addition to supporting a wide range of analytical and data control applications, this solution improves maintenance efficiency.

Liquid analyzers are used in the oil, petrochemical, iron and steel, electric power, water supply, wastewater treatment, and many other industries. These analyzers are necessary to control the quality of raw materials and products, monitor reactions, and manage water treatment. Conventional liquid analyzers are composed of a sensor and a transmitter that converts the sensor's analog signals into digital signals for transmission over communications networks and the real-time display of data.

Data acquisition systems are often used in plants to collect and log data from liquid analyzers. In 2013, Yokogawa released the SENCOM series of pH/ORP sensors, which are able to process digital signals and store calibration data and other types of information in digital form. This eliminates the need for a transmitter and allows direct connections with PCs and other digital devices. SENCOM sensors come with a communication interface and custom-made pH/ORP display templates for use with the SMARTDAC+ recorders.

Key Benefits:

  • Easy to maintain
  • Easy navigation and high flexibility and expandability

Emerson’s condition monitoring system expands protection to more field assets

CSI3000.jpgEmerson Process Management has introduced the CSI 3000 Machinery Health Monitor, a compact protection system for a wide range of machinery such as pumps, compressors, centrifuges, blowers, and generators. The CSI 3000 delivers protection data in situations where a standard rack-based system simply will not fit or is not a cost-effective approach. Easy assembly and user-friendly, customizable setup means the CSI 3000 has a short path out of the box to improving availability and ensuring safety of rotating assets.

The CSI 3000 measures shaft vibration, bearing vibration, position, speed and generates key signals. The system provides the user with alarm outputs for each channel and does not require additional signal converters for shaft vibration and displacement measurements.

“Emerson offers a complete line of protection monitors – from the rack-mounted CSI 6500 online monitoring system and the basic CSI 9360 Vibration/Position Transmitter, to the CSI 6300 SIS that guards against overspeed conditions,” said Björn Müller, Emerson’s product manager of online sensors. “This is another example of how we are delivering capabilities that bring stability to our user’s operations through services and technologies that reduce downtime and improve availability.”

 

ABB launches new flow calibration and valve testing guides

ABB’s Measurement and Analytics business has launched two new guides covering its services for flow calibration and valve testing. Available on request from This email address is being protected from spambots. You need JavaScript enabled to view it., the guides explain how ABB’s flow calibration facilities at its Stone house and Workington factories can be used to help check the accuracy of flowmeters and control valves.

For flow calibration, the facilities enable a wide variety of flowmeter types to be calibrated to the leading international standards. All calibrations are carried out to ISO9000, with the option of a UKAS accredited calibration where the certificate carries the ILAC and UKAS Calibration Laboratory 0255 logo.

The flow calibration guide explains how the facilities can be used to calibrate meter sizes from 1mm to 2.4 metres at accuracies down to ±0.1%. It also covers the range of calibration techniques available, including gravimetric, volumetric or comparison methods, describing each technique and explaining how to choose the right method.

The valve testing guide covers ABB’s ability to test control valves from 25mm up to six metres and weighing up to 10 tonnes in accordance with the EN ISO 60534-2-3 standard for control valve testing.

The guide outlines the testing process and discusses the benefits of ABB’s service, which enables valve users to ensure that their valves have been tested for their specific requirements. Both services are offered via ABB’s Measurement & Analytics Products Service team and are part of a wider service capability spanning ABB’s entire portfolio of instruments and analysers.

The vital role performed by flowmeters, control valves or any form of instrument or analyser means that it is worth investing the money, time and effort in ensuring that devices are properly serviced throughout their lifetime, from installation and commissioning through to upgrade or replacement.

Our flowmeter calibration and valve testing services are just two examples of our wider service offering, which can help our customers to enjoy continued accuracy and high performance from their equipment throughout its operational life.

YTC positioners lead the way in tough applications

YTC positioners.jpgProcess industries often depend on high performance valve actuation in harsh environments. Despite the difficult surroundings, process plants demand the latest technology, such as smart positioners, which allow technicians to use auto-calibration and simple diagnostics to commission and monitor their entire system at the push of a button. In many cases, the valve, actuator and smart positioner package is exposed to extreme temperatures, dirty conditions and other challenges such as high vibration.

Most instrumentation positioners would fail quickly when subjected to these harsh environments. For example, smart positioners require internal electrical components which are extremely vulnerable at high temperatures and may prematurely fail when exposed. Young Tech Company (YTC) has developed two smart positioner products to thrive under these conditions which have paved the way to expansion and growth in tough process control applications.

Remote sensing unit positioners:

The YT-3301 introduced the concept of isolating and detaching the sensing feedback portion of the positioner from the main control housing. The sensing unit accurately detects the position of the valve stem and provides a feedback signal to the main housing. This dual unit design allows the operator to locate the precision electronics elements at a considerable distance from the valve environment, providing the best of both worlds – precision engagement at the point of valve movement and a clean, dry and ambient temperature for the electronics. This also facilitates mounting multiple control housings in close proximity for convenient and time saving monitoring and adjustment of valves in the plant.

Triple module remote positioners:

Remotely mounting the sensing unit provides dramatically improved reliability and performance, but at longer distances between the sensing unit and the control housing pneumatic signal loss may occur. In extreme situations this could lead to hunting and oscillation of the electronics and reduced valve and actuator positional stability.

To assure superior performance in these difficult applications, YTC has developed the YT-3302 Positioner. With this product a third module, housing the driving components of the pilot valve and torque motor assembly, is mounted at an intermediate location between the remote sensing unit and the main control unit. Accordingly, the three modules are the sensing unit, driving unit and control housing. As the sensing unit contains the most robust components and the control the most sensitive, this configuration delivers higher performance with dramatically increased positional accuracy.

 

Added benefits include the ease of maintenance for each of the modules and the ability to gang mount modules at convenient locations. Standardisation of modules and components also facilitates spare part simplification and inventory cost reduction.

Yokogawa Releases New UTAdvanced® Series DIN Rail mounting Type Controllers

UTAdvanced® Series DIN Rail Controllers.jpgYokogawa Electric Corporation announces that it will be releasing a number of new UTAdvanced® series controllers on April 24. The new controllers include four DIN rail*1 mounting type controllers and one 1/8 DIN panel type program controller. This is part of Yokogawa's ongoing effort to expand its controller business by satisfying market needs and giving customers a greater range of choices.

Development Background:

UTAdvanced series controllers are mounted on furnaces and other types of heat process-related industrial facilities for the measurement, display, and control of operating variables such as temperature, pressure, and flow rate.

In recent years, it has become more common for equipment manufacturers to integrate the setting, manipulation, and display functions of programmable logic controllers (PLC) and other embedded control devices on touch panels and other types of user interfaces, and to mount the hardware on DIN rails inside panel boxes. There is an increasing need for such DIN rail mounting type controllers.

The UTAdvanced series controllers come in two sizes: 1/4 DIN and 1/8 DIN. While 1/4 DIN controllers are more popular because they have large display panels and provide a wider range of I/O signal choices, there are certain applications where space is at a premium that require a smaller device. For just such applications, Yokogawa has added more 1/8 DIN controllers to its product lineup.
