Amphenol Advanced SensorsNPI-19 Series Specifications Current Driven Medium Pressure, A Media Isolated Pressure Sensor -Out The modular design allows for a variety of pressure The NovaSensor NPI Series incorporates state-of- R 1 D port modules, which are hermetically welded to the the-art IsoSensor technology, which gives the OEM +In sensor header module. Standard types A, B, H, and user the best in price and performance. They are 4 J are shown inside. designed to operate in hostile environments and R yet give the outstanding sensitivity, linearity, and 2 For compensation of temperature effects, a hysteresis of a silicon sensor. The piezoresistive B complete resistor network is supplied on a hybrid sensor chip is housed in a fluid filled cylindrical +Out 5 ceramic substrate. The IsoSensor design minimizes 3 cavity and isolated from measured media by a temperature errors to provide a maximum offset stainless steel diaphragm and body.
