Pressure Sensor

Process control systems Hydraulic systems and valves Biomedical instruments Refrigeration and HVAC controls Appliances and consumer electronics Ship and marine systems Aircraft and avionic systems NPI media isolated sensors are designed to operate in hostile environments and yet give the outstanding sensitivity, linearity, and hysteresis of a silicon sensor. The piezoresistive sensor chip is housed in a fluid-filled cylindrical cavity and isolated from measured media by a stainless steel diaphragm and body. The NPI Series employs SenStable® processing technology, providing excellent output stability. Available in either constant current or constant voltage version. The modular design allows for a variety of pressure port modules, which are hermetically welded to the sensor header module. There are other standard port styles available. Please consult NovaSensor for more details.

The NovaSensor® NPI Series incorporates state-of-the-art IsoSensor technology, which gives the OEM user the best in price and performance. They are designed to operate in hostile environments and yet give the outstanding sensitivity, linearity, and hysteresis of a silicon sensor. The piezoresistive sensor chip is housed in a fluid filled cylindrical cavity and isolated from measured media by a stainless steel diaphragm and body. As with all NovaSensor® silicon sensors, the NPI Series employs SenStable® processing technology, providing excellent output stability.
