Voltage compensation allows the sensor to be connected directly to the power supply, thereby eliminating the need for additional components to construct a constant current source. These sensors enable field interchangeability with a calibrated FSO of 100 mV ±1 %. As with all NPI media isolated sensors, 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 the measured media by a stainless steel diaphragm and body. The NPI Series employs SenStable® processing technology, providing excellent output stability. The modular design allows for a variety of pressure port modules which are hermetically welded to the sensor head module. Standard types A, B, H, and J are shown to the right. For compensation of temperature effects, a resistor network is supplied on a hybrid ceramic substrate. The IsoSensor design minimizes temperature errors to provide a maximum offset error of 1.0% FSO and a maximum full scale output error of 0.75% FSO over the 32°F to 158°F (0°C to 70°C) compensated range.
