Overview

The 1 PSI-D-HGRADE-MV is a high-grade differential pressure sensor from Amphenol All Sensors featuring a temperature-compensated Wheatstone bridge output. It is designed for precision low-pressure measurements up to 1 PSI (6.89 kPa) and provides a millivolt-level output proportional to the applied differential pressure. This sensor is housed in a 6-SIP module with dual 0.19-inch barbless ports, making it suitable for direct PCB mounting in sensitive pneumatic applications.

Why Choose This Part

This H-Grade variant offers a high accuracy of +/-0.5% and is fully temperature compensated from 0 to 70 degrees Celsius. Its Wheatstone bridge architecture allows for highly linear output, while the dual-port design facilitates easy integration into differential sensing loops.

Applications

Medical Instrumentation
Ideal for patient monitoring, respiratory equipment, and ventilators where accurate low-pressure air flow measurement is critical.
HVAC Control Systems
Used in VAV box controllers and filter monitoring to detect small pressure drops across air filters or ducts.
Environmental Monitoring
Suitable for cleanroom pressure monitoring and weather station equipment requiring high-resolution differential sensing.

Getting Started

As a ratiometric bridge sensor, it requires a stable excitation voltage (typically 12V) and an external instrumentation amplifier or a high-resolution ADC with a programmable gain amplifier (PGA) to process the 18mV full-scale signal. Engineers should ensure clean, dry air is used as the pressure medium to maintain the specified accuracy and longevity of the internal sensing element.
