Overview

The 100 PSI-D-4V-ASCX is a temperature-compensated, amplified differential pressure sensor designed for high-accuracy applications up to 100 PSI. It provides a ratiometric analog voltage output with a 4.5V span, operating on a standard 5V DC supply. The sensor utilizes a proprietary ASCX series technology to minimize errors over a 0 to 70 degrees Celsius temperature range.

Why Choose This Part

The sensor features an internal circuit that provides both amplification and temperature compensation, significantly reducing the complexity of the external signal conditioning circuit. With a calibrated zero and span, it ensures a tight +/-0.5% accuracy and a high-level output signal suitable for direct interface with microcontroller ADCs.

Applications

Pneumatic Control Systems
Monitoring pressure differentials in factory automation and high-pressure pneumatic lines.
Medical Instrumentation
Precise air pressure monitoring in respiratory equipment and diagnostic machines.
HVAC System Monitoring
Measuring pressure drops across filters or within ducts for airflow management.
Environmental Testing
Utilized in instrumentation for measuring atmospheric or fluid pressure differentials in field equipment.

Getting Started

To integrate this sensor, connect the 5V DC supply and ground pins as specified in the 4-SIP pinout. The analog output voltage (0.25V to 4.75V) can be sampled by a 10-bit or 12-bit ADC; use a simple RC low-pass filter on the output to reduce high-frequency noise in industrial environments. Ensure the dual 0.19 inch ports are connected using appropriately rated barbless tubing for 100 PSI operation.
