NPI-19A-300GV

Pressure Sensors Transducers Overview

The NPI-19A-300GV is a vented gauge pressure sensor from the NPI-19 series, manufactured by Amphenol Advanced Sensors (NovaSensor). It features a cylindrical package with a 1/2 inch UNF threaded port. The device measures pressures up to 300 PSIG (2068.43 kPa) and offers an analog millivolt output ranging from 0 mV to 100 mV. It operates on a 10 V supply voltage and provides ±0.5% static accuracy. The sensor utilizes SenStable® technology for stability and includes temperature compensation within the 0°C to 70°C range.

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 process medium.
• SenStable® processing technology ensures high output stability and reliability in harsh environments.
• Integrated resistor network on a hybrid ceramic substrate provides complete temperature compensation.
• Modular construction allows various pressure port modules to be hermetically welded to the sensor joint module.

Pressure Sensors Transducers Applications

• Process control systems
• Hydraulic systems and valves
• Biomedical instruments
• Refrigeration and HVAC controls

Pressure Sensors Transducers Procurement Notes

Verify the specific part number against official Amphenol NovaSensor documentation to confirm the exact pressure range, output type, and port configuration. Ensure the application environment falls within the specified operating temperature limits and that the required supply voltage matches the sensor's electrical characteristics before procurement.

Pressure Sensors Transducers Selection Notes

Select this model when a rugged, media-isolated analog pressure sensor is required for moderate pressure ranges. The 1/2 inch UNF port facilitates mounting in industrial applications. Consider the linear millivolt output compatibility with existing signal conditioning circuits. Verify that the static accuracy meets the system requirements for the intended hydraulic or pneumatic measurement task.

Pressure Sensors Transducers Part Context

This component belongs to the NPI-19 series of mid-pressure sensors designed for harsh environments. The series employs piezoresistive silicon technology encapsulated in a robust cylindrical housing. The 'A' suffix typically denotes a specific port configuration, while '300GV' indicates the 300 PSIG vented gauge pressure rating and analog voltage output.

Pressure Sensors Transducers Replacement Considerations

NPI-19B-300GV: Features a different port style compared to the NPI-19A variant. NPI-19H-300GV: Offers a 1/4 inch NPT port instead of the 1/2 inch UNF thread. NPI-19J-300A2: Provides digital I2C output rather than analog millivolt, requiring different interface circuitry.
