Pressure TrasmitterGems Sensors & Controls’ 31CS and 32CS Series intrinsically safe pressure transmitters have been approved by CSA to the standards required for use in hazardous areas in both the U.S. and Canada. The two new series are identical, with the exception of the pressure diaphragm. The 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 Gems 3100 & 3200 Series products, when used with a zener barrier the CS Series pressure 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; and Class I, Zone 0 AEx ia IIB T4 Ga. Applications include hazardous area installations, such as wellhead automation, gas distribution, and gas compressors.
