Intrinsically Safe Pressure Transmitters Meet CSA Demands

Feb. 13, 2013

Gems Sensors & Controls announces the introduction of the 31CS and 32CS Series 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. Based on the successful Gems 3100 & 3200 Series products, when used with a zener barrier the CS Series transmitters are certified for operation in the following areas: 

  • Class I, Division 1, Groups C and D 
  • Class I, Zone 0 Ex ia IIB T4 Ga 
  • 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. This enables 31CS/32CS Series transmitters to reduce time and cost of installation. 

Both the 31CS and 32CS Series feature proven 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. Exceptional long-term stability (0.2% full scale/year drift) and high accuracy (0.25% full scale) together with high resistance to shock and vibration makes this product ideal for demanding applications.
