NPI-15B-702SH

Pressure Sensors Transducers Overview

The NPI-15B-702SH is a high-pressure industrial sensor from the Amphenol NovaSensor NPI-15 series. It features a sealed gauge pressure type with a working pressure of 1000 psi (6894 kPa). The device utilizes a piezoresistive silicon chip encapsulated in a liquid-filled cavity isolated by a 316 stainless steel diaphragm and housing. It provides a millivolt output of 200 mV at a 10 V supply voltage, with an accuracy of 0.3%. The unit operates within a temperature range of -40°C to +125°C and employs SenStable technology for output stability.

Pressure Sensors Transducers Feature Summary

• Utilizes IsoSensor design with a liquid-filled cavity to isolate the piezoresistive chip from corrosive media using a 316 stainless steel diaphragm.
• Incorporates SenStable processing technology to ensure excellent output stability and resistance to hysteresis effects in harsh environments.
• Features mixed ceramic substrate circuitry for temperature compensation, minimizing zero thermal error across the operating range.

Pressure Sensors Transducers Applications

• Hydraulic system pressure monitoring
• Gas pressure detection in industrial settings
• Applications involving steam or weakly corrosive media

Pressure Sensors Transducers Procurement Notes

Verify the specific pressure rating and port configuration against project requirements, as the NPI-15 series includes variants with different ports such as NPT or UNF. Confirm that the sealed gauge pressure type aligns with the application's reference needs. Ensure the 10 V supply voltage and millivolt output interface are compatible with the host signal conditioning circuitry before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this model for applications requiring high-pressure measurement up to 1000 psi with robust corrosion resistance. The 316 stainless steel construction makes it suitable for aggressive media. Consider the millivolt output requirement; if amplified signals are needed, verify compatibility with external amplification circuits. The wide operating temperature range supports use in demanding industrial environments.

Pressure Sensors Transducers Part Context

This component belongs to the NPI-15 series of high-pressure sensors manufactured by Amphenol Advanced Sensors under the NovaSensor brand. The series is designed for OEM users seeking high sensitivity and linearity in severe conditions. The NPI-15B variant specifically denotes the sealed gauge pressure type within this high-pressure lineup.

Pressure Sensors Transducers Replacement Considerations

Cross-reference with other NPI-15 series models like NPI-15A-702SH or NPI-15H-702AH for different pressure types or port styles. Verify that substitute parts maintain the same 1000 psi working pressure and 200 mV output characteristics to ensure functional equivalence.
