Overview

The MPX5100DP is a high-performance differential pressure sensor designed to measure air or liquid pressure differences up to 100 kPa (14.5 psi). This sensor integrates on-chip signal conditioning, temperature compensation, and calibration to provide a linear analog voltage output ranging from approximately 0.2 V to 4.7 V. Its unibody package with dual barbed ports makes it ideal for direct board mounting in systems requiring precise pneumatic or hydraulic monitoring.

Why Choose This Part

The sensor features a high sensitivity of 45 mV/kPa and maintains a low maximum error of 2.5 percent over a wide temperature range of 0 to 85 degrees Celsius. Its patented silicon shear stress strain gauge technology ensures long-term stability, while the durable epoxy unibody housing protects the internal circuitry from environmental stress.

Applications

Patient Monitoring
Used in medical ventilators and respiratory equipment to monitor differential air flow and pressure levels.
Process Control
Ideal for industrial automation systems that require precise pressure regulation in pneumatic lines.
Pump and Motor Control
Monitors pressure drops across filters or valves to optimize pump performance and detect blockages.
HVAC Airflow Sensing
Measures the pressure difference between two points in a duct to calculate flow rate and air volume.

Getting Started

To interface the MPX5100DP, connect the output pin to a 10-bit or higher analog-to-digital converter (ADC) on a microcontroller powered at 5V. Use a decoupling capacitor (typically 1.0 uF) near the sensor power supply pins and an RC filter on the output line to minimize signal noise in industrial environments.
