NPI-19B-100AV

Pressure Sensors Transducers Overview

The NPI-19B-100AV is a medium-pressure absolute pressure sensor from the Amphenol NovaSensor NPI-19 series. It features a rugged cylindrical design with a 1/2-inch UNF threaded port and soft wire termination. The device measures up to 100 psi (689.48 kPa) with a maximum overpressure rating of 200 psi (1378.95 kPa). It delivers an analog output ranging from 0 mV to 100 mV via a Wheatstone bridge configuration, powered by a 10 V supply. Accuracy is specified at ±0.25%, and it operates within a temperature range of -40°C to 125°C.

Pressure Sensors Transducers Procurement Notes

Verify that the specific part number matches the required pressure type, as the NPI-19 series includes gauge and sealed variants. Confirm the 10 V excitation voltage requirement against system power capabilities. Ensure the 1/2 inch UNF port size aligns with existing mechanical interfaces. Check RoHS compliance status if environmental regulations apply to the final assembly.

Pressure Sensors Transducers Selection Notes

Select this model when a robust, media-isated analog sensor is needed for pressures up to 100 psi. The 100 mV full-scale output requires appropriate signal conditioning. Consider the wide operating temperature range for extreme environment applications. Verify compatibility with the 10 V supply voltage before integration into the circuit design.

Pressure Sensors Transducers Part Context

This component belongs to the NPI-19 series of industrial pressure sensors manufactured by Amphenol Advanced Sensors. The series utilizes piezoresistive silicon sensor chips mounted in fluid-filled cylindrical cavities. This design isolates the sensing element from the process media while maintaining high sensitivity and linearity typical of silicon-based technologies.
