NPI-19J-300GV

Pressure Sensors Transducers Overview

The NPI-19J-300GV is a medium-pressure industrial gauge pressure sensor from the Amphenol NovaSensor NPI-19 series. It features a 300 psi working pressure range with a 600 psi maximum overload rating. The device utilizes a solid-state piezoresistive design with a 1/8 inch - 27 NPT male port for process connection. It provides a millivolt output of 0 to 100 mV at a standard 10 V excitation voltage, achieving ±0.25% accuracy. The sensor operates within a temperature range of -40°C to +125°C and includes full temperature compensation.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required port threading and electrical output specifications. Confirm that the operating environment remains within the specified -40°C to +125°C thermal limits. Ensure the system supply voltage does not exceed the maximum rating to prevent sensor damage. Cross-reference the part number with the manufacturer's latest documentation to confirm current production status and availability.

Pressure Sensors Transducers Selection Notes

Select this model when a robust, isolated gauge pressure measurement is required for medium-pressure applications up to 300 psi. The NPI-19J-300GV is suitable for designs needing a threaded NPT connection and analog millivolt output. Consider the ±0.25% accuracy and wide temperature range for precision industrial requirements. Evaluate the physical dimensions and panel mount style against the installation constraints of the target system.

Pressure Sensors Transducers Part Context

This component belongs to the NPI-19 series of medium-pressure sensors manufactured by Amphenol Advanced Sensors under the NovaSensor brand. The series is characterized by its modular design, allowing various pressure port modules to be welded to the sensor junction module. These sensors are engineered for durability and performance in demanding industrial settings where long-term stability is critical.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes within the same family include NPI-19J-200AV (200 psi absolute) and NPI-19J-172GH (250 psi gauge). Verify that alternative part numbers match the required pressure type (gauge vs. absolute), output signal, and port size before implementation.
