NPI-19B-300GV

Pressure Sensors Transducers Overview

The NPI-19B-300GV is a media-isolated industrial pressure sensor from the NovaSensor NPI-19 series, manufactured by Amphenol Advanced Sensors. It features a cylindrical package with a 1/2 in-20 UNF threaded port and outputs a millivolt signal ranging from 0mV to 100mV. The device operates on a 10V supply voltage and supports a working pressure of 300 PSIG (2068.43 kPa) with a maximum pressure of 600 PSIG. It offers an accuracy of ±0.25% and functions within a temperature range of -40°C to +125°C.

Pressure Sensors Transducers Feature Summary

• Media-isolated design using a fluid-filled cylindrical cavity and stainless steel diaphragm to protect the piezoresistive chip from direct contact with the measured medium.
• SenStable processing technology integrated into a hybrid ceramic substrate resistor network to provide output stability and compensate for temperature effects.

Pressure Sensors Transducers Applications

• Process control systems
• Hydraulic systems and valves
• Biomedical instruments

Pressure Sensors Transducers Procurement Notes

Verify the specific port configuration and electrical output requirements against the official datasheet before ordering. Confirm that the 1/2 in-20 UNF thread matches the installation interface. Ensure the 10V excitation voltage aligns with the system power supply capabilities. Check RoHS compliance status if required by project specifications.

Pressure Sensors Transducers Selection Notes

Select this model when a robust, media-isated solution is required for high-pressure industrial environments up to 300 PSIG. The NPI-19B variant provides a threaded connection suitable for panel mounting or direct piping integration. Consider the millivolt output compatibility with downstream amplification circuits or data acquisition systems requiring analog signals.

Pressure Sensors Transducers Part Context

This component belongs to the NPI-19 series of industrial pressure sensors, which are designed for harsh environments. The series utilizes silicon sensor technology combined with modular port designs welded airtight to the sensor joint module. This architecture ensures high reliability and sensitivity while maintaining linear performance and low hysteresis across the operating range.

Pressure Sensors Transducers Replacement Considerations

NPI-19A-300GV: Features a different port style compared to the B variant. NPI-19H-300GV: Utilizes a 1/4 in-18 NPT threaded port instead of the UNF thread found in the NPI-19B-300GV.
