PCB Piezotronics, Inc. (PCB) has introduced a series of dynamic, ICP pressure sensors that have been certified under ATEX and CSA for use in hazardous environments. These sensors are widely used on pumps, compressors, power generation equipment, and other machinery operating in hazardous environments. 

Series 102 and 121 pressure sensors are ideal for monitoring performance of compressors, pumps, and gas turbines, because they measure dynamic pressure events such as surges, pulsations, and spikes.  These sensors also detect wellhead acoustics to determine properties of mud & water.  Sensors may be used with ICP signal conditioning and permit the use of a variety of inexpensive two-wire cable systems.  The low-impedance signal may be transmitted over long cable distances, and the sensors may be used in dirty environments with no signal degradation.  Various mounting configurations are available, with pressure ranges from 50 to 5,000 psi (345 to 345,000 kPa), and sensitivities from 1 to 100 mV/psi (0.15 to 14.5 mV/kPa).
