Sealed Industrial Pressure Sensors

Dec. 17, 2008
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.* Pressure Ranges 0 – 6 to 0 – 400 Bar or 0 – 100 to 0 – 5,000 PS Absolute, Sealed Gage * Supply Voltage 5Vdc ±0.5Vdc * Output 0.5Vdc to 4.5Vdc * Technology Piezo Resistive * Main Seal Weld * Media Compatibility Broad Compatibility * Operating Temp -40°C to 100°C * Accuracy* 0.50% * Total Error Band ±2% (-15°C to 85°C) * Main Housing 304L Stainless Steel * Wetted Surface 304L Stainless Steel * Ingress Protection IP66 * RoHS Compliant Yes * CE Mark Yes
