Manually energised solution for failsafe valve actuators

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.

NI Offers Measurement Microphones Through G.R.A.S. Sound and Vibration

National Instruments today announced that NI Alliance Partner G.R.A.S. Sound & Vibration, a leading producer of acoustic front-end products, now sells microphone kits for use with NI dynamic signal acquisition (DSA) hardware. NI offers several different microphone types, from array microphones to condenser microphones appropriate for class 1 sound-level measurements. Customers in a number of industries, including aerospace and defense, are already having success using these products for applications like acoustic holography, environmental noise, noise mapping and sound power.

“For more than 10 years G.R.A.S. and NI have worked together on joint projects, and there has always been a great collaboration between our companies,” said Peter Wulf-Andersen, managing director at G.R.A.S. Sound & Vibration. “I am proud that one of the biggest players in the industry has chosen G.R.A.S. as an official partner.”

NI’s new microphone kits include a G.R.A.S. microphone capsule and preamplifier. Inside the capsule is a diaphragm made of a special stainless alloy that provides maximum sensor life. The microphones contain a Transducer Electronic Data Sheet (TEDS) chip and combine with NI DSA hardware to provide a plug-and-play sensor experience.

Siemens expands and rebrands its dry solids flowmeter line

Siemens-Division Industry Automation expands its dry solids flowmeter product line with the new Sitrans WF100, Sitrans WF200, and Sitrans WF250 strain-gauge load cell based flowmeters. These new flowmeters provide effective measuring for compact installations and high capacity applications. Siemens also rebrands its Linear Variable Differential Transformer (LVDT) based Milltronics flowmeters into the Sitrans WF300 series.

Sitrans WF100 handles flowrates of 1 to 200 t/h (1 to 220 STPH), while the Sitrans WF200 series handles flowrates of 200 to 900 t/h (220 to 990 STPH). Sitrans WF250 is for use with air-activated gravity conveyors or air slides, typically found in cement processing. The Sitrans WF250's unique design includes an air chamber that separates the air from the material, thereby removing the impact of air on the sensing plate and providing accurate measurement. All of the Sitrans WF100 and Sitrans WF200 series flowmeters use patented triple beam parallelogram style load cells that have proven their reliability and durability for over 25 years in Siemens heavy-duty belt scales, offering superior accuracy and repeatability.
