Intrinsically Safe Pressure Transmitters Meet CSA Demands

Gems Sensors & Controls has launched the 31CS and 32CS series of intrinsically safe pressure transmitters. These series have been approved by CSA to the standards required for both USA and Canadian use in hazardous areas.

The two new series are identical, with the exception of the pressure diaphragm. 32CS Series transmitters feature a thicker diaphragm and a pressure restrictor to withstand the rigors of cavitation or extreme pressure spikes, improving stability and reliability in pulsating applications.

When used with a zener barrier the CS Series transmitters are certified for operation in Class I, Division 1, Groups C and D; Class I, Zone 0 Ex ia IIB T4 Ga; and Class I, Zone 0 AEx ia IIB T4 Ga.

Applications include hazardous area installations, such as wellhead automation, gas distribution and gas compressors. 31CS/32CS transmitters are compact and durable in harsh outdoor environments. They may be directly fitted to pipe work, so require none of the small bore pipe work needed to remotely utilize non-Division 1 certified transmitters.

Both the 31CS and 32CS series feature sputtered thin-film sensing technology, 17-4 PH stainless-steel wetted parts and ASIC-controlled thermal compensation and signal conditioning. They are available in a wide variety of factory-configured settings or may be configured to the customers application needs.
