Amphenol NPI-19J-101AH

The NovaSensor NPI series utilizes advanced IsoSensor technology to offer OEM users the best price-to-performance ratio. Designed for harsh environments, they retain the excellent sensitivity, linearity, and hysteresis characteristics of silicon sensors. The piezoresistive sensor die is housed in a fluid-filled cylindrical cavity and isolated from the measured media by a stainless steel diaphragm and body. Like all NovaSensor silicon sensors, the NPI series employs SenStable® processing technology for outstanding output stability. The modular design allows the use of various pressure port modules, which are hermetically welded to the sensor head module. To compensate for temperature effects, a complete resistor network is provided on a hybrid ceramic substrate. The IsoSensor design minimizes temperature errors, with a maximum offset error of 0.75% FSO over a compensated range of 32°F to 158°F (0°C to 70°C).
