NPI-19J-701GH

Pressure Sensors Transducers Overview

The NPI-19J-701GH is a vented gauge pressure sensor from the NPI-19 series by Amphenol Advanced Sensors. It features a cylindrical package with a male 1/8-inch (3.18mm) NPT port and soft wire termination. The device measures pressures up to 101.53 PSI (700 kPa) with a maximum overpressure rating of 203.05 PSI (1400 kPa). It provides an analog output via a Wheatstone bridge, ranging from 0 mV to 100 mV. The sensor operates within a temperature range of -40°C to 125°C and includes temperature compensation.

Pressure Sensors Transducers Feature Summary

• Media-isolated design using a stainless steel diaphragm protects the piezoresistive silicon chip from corrosive fluids.
• Temperature-compensated operation ensures stable performance across a wide industrial temperature range.
• Robust cylindrical construction allows for secure panel mounting in hostile environments.

Pressure Sensors Transducers Applications

• Industrial automation systems requiring reliable pressure monitoring
• HVAC equipment utilizing gas or liquid media measurement
• Process control instrumentation demanding high linearity and sensitivity

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm port size, pressure range, and output type match the application requirements. Ensure the operating environment does not exceed the specified temperature limits or overpressure ratings. Confirm that the analog millivolt output interface is compatible with the host system's signal conditioning circuitry before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this model when a vented gauge reference is required rather than absolute pressure. The analog Wheatstone bridge output necessitates external amplification or ADC integration. Consider the physical dimensions of the cylindrical package for panel cutout compatibility. Evaluate the 1/8 NPT thread connection against available piping standards to ensure proper sealing and installation without additional adapters.

Pressure Sensors Transducers Part Context

This component belongs to the NPI-19 series of industrial pressure sensors. The series utilizes piezoresistive technology housed in fluid-filled cavities isolated by stainless steel bodies. This design prioritizes durability and accuracy in harsh conditions while maintaining low hysteresis characteristics typical of silicon-based sensing elements.

Pressure Sensors Transducers FAQ

What is the maximum overpressure limit for the NPI-19J-701GH?

The maximum overpressure rating is 203.05 PSI (1400 kPa), which is double the working pressure of 101.53 PSI.

Is the sensor suitable for measuring liquid pressure?

Yes, the NPI-19 series is designed to measure both gas and liquid media due to its stainless steel isolation diaphragm.
