Sealed Industrial Pressure Sensors


These sealed industrial pressure sensors that incorporate a stainless steel diaphragm in an all welded 304L stainless steel housing making them well-suited for hostile environment applications.  The sensors utilize Kavlico’s oil-filled piezo-resistive (PRT) sensing technology along with a state-of-the-art ASIC. Rugged by design, the sensors are capable of operating with a wide array of fluids and gases that are compatible with stainless steel.

Pressure ranges are available from 0-100 through 0-5,000 PSI absolute or sealed gage for the models P251/P251R and 0-6 through 0-400 Bar for the models P250/P250R.  The P250/P251 operate on a 5 Vdc power supply and provide a ratiometric 0.5 to 4.5 Vdc linear amplified output proportional to pressure while the P250R/P251R have an internal regulator and operate on 9 to 32 Vdc while providing a regulated 5 Vdc or 10 Vdc linear amplified output proportional to pressure.  Each sensor is temperature compensated and exhibit excellent EMI/RFI rejection capability.  The high reliability sensors have an over-pressure capability of 2X FSO (Full Scale Output) and have been designed to operate in situations with large over-pressure spikes.

Typical industrial applications include refrigerant control and recovery, pumps and compressors, process control, water management, autoclaves, hydraulic systems, and test and monitoring equipment.

A wide variety of 12 standard electrical and 10 standard process connection options allow the sensors to be configured to meet each end-users application-specific requirement.
