Yokogawa Electric Corporation announces that it will release an enhanced version of the DPharp EJA series pressure/differential pressure transmitters, one of its core sensor products, on June 20.

While remaining in the same price range, the enhanced DPharp EJA series transmitters will now offer significantly improved performance and functionality, bringing great cost benefits to our customers. As standard features, they will have the same high-speed response and multi-sensing functionality available with the high-end DPharp EJX series.

Rotork has introduced an innovative range of manually energised spring-return actuators to provide an economical solution for failsafe valves that are infrequently operated.

The Rotork ManPower range greatly reduces installation time and expense since no external electrical, hydraulic or pneumatic power supply is required. Suitable for a wide range of ball, butterfly and plug valves, the scotch-yoke actuators are equipped with a compact, self-contained manually operated hydraulic power pack. A hydraulic hand pump on the power pack is used to operate the actuator and compress the failsafe spring, holding the valve in the desired open or closed position until a failsafe signal is received, at which point the spring will immediately drive the valve to the safe position.

Failsafe operation of ManPower units can be triggered by electrical signals, high or low pressure pilots or fire sensors, enabling the successful fulfilment of many ESD (Emergency Shutdown) and pressure related protection duties in the oil, gas, petrochemical and pipeline industries.

Rotork ManPower actuators are available with output torques up to 45,000 Nm, with explosionproof and watertight certification to international standards. A wide range of options includes local position indication, integral limit switches, speed control, high speed operation, local electrical controls, manual reset and corrosion resistant trims. Where space is restricted the ManPower hydraulic module can be located separately from the valve. Standard units are suitable for a temperature range from -23ºC to +60ºC and equipped with built-in temperature compensation.

Zurich, Switzerland, Apr. 24, 2012 – ABB, the leading power and automation technology group, announced the release of several new products as part of its Symphony™ Plus total plant automation platform for the power generation and water industries.

The new products include a new high-performance process controller named Symphony Plus Control HPC800 and three interface modules that expand the connectivity of the controller to intelligent electronic devices using the PROFIBUS DP and HART communication protocols.

HPC800 joins existing Symphony Plus Rack controllers and is suitable for applications that require modular DIN rail packaging. It also features a fast ethernet-based plant network that makes it ideal for geographically distributed control applications in conventional or renewable power plants and water networks.

The new controller combined with PROFIBUS and HART enables integration of intelligent devices such as smart transmitters, actuators, motor control centers, flame scanners and other electronic products. By using the same function code algorithms as Symphony Plus, Harmony, and INFI 90, the HPC800 controller enables customers to effectively reuse their extensive library of ABB control solutions.

“These new products are designed to provide maximum system flexibility, reliability and efficiency” said Franz-Josef Mengede, head of ABB’s Power Generation business, a part of the company’s Power systems division. “The initiative supports ABB’s continued commitment to Symphony Plus and is part of our ‘evolution without obsolescence' approach of introducing new technology while protecting the long-term investment of customers by ensuring compatibility with preceding generations.”

The Amplicon Measurement & Control Group has launched the Moxa ioPAC 8000 series RTU Controller, a ruggedized and reliable RTU controller suitable for all harsh environments, but designed specifically for rail applications.

The Moxa ioPAC 8000 series modular RTU controllers are designed for remote data acquisition and monitoring. With a powerful processor and a variety of interfaces, the ioPAC 8000 can connect to PLCs, other serial devices and smart meters. They are suitable for applications that require a rugged and reliable design.
