Overview

The 30 PSI-D-4V-ASCX is a temperature compensated, amplified differential pressure sensor from Amphenol All Sensors. It provides a ratiometric analog output between 0.25 V and 4.75 V, designed for measuring pressures within a +/-30 PSI range with high accuracy.

Why Choose This Part

This sensor features an internal circuit that provides an amplified and calibrated output, reducing the need for external signal conditioning. It maintains a high level of accuracy at +/-0.5% while offering temperature compensation to ensure stability across a 0 to 70 degrees Celsius operating range.

Applications

HVAC Airflow Monitoring
Differential pressure measurement for filter monitoring and air volume control in industrial ventilation systems.
Medical Respiratory Equipment
Precise monitoring of gas flow and pressure in non-critical medical diagnostic devices.
Industrial Process Control
Measurement of pressure drops across valves and filters in low-pressure industrial pneumatic circuits.
Environmental Monitoring
Differential air pressure sensing for cleanroom environments and laboratory fume hoods.

Getting Started

To integrate this sensor, provide a stable 4.5V to 5.5V supply and connect the 4-SIP leads to an analog-to-digital converter (ADC) on a microcontroller. Since the output is ratiometric, ensure your ADC reference voltage is stable or derived from the same supply to maintain measurement precision.
