Overview

The NPA-500B-015D is a surface-mountable differential pressure sensor providing a 0.5 V to 4.5 V amplified analog output. Part of the NovaSensor NPA series, it features internal temperature compensation and signal conditioning in a compact SOIC-14 module package. It is designed to measure pressures up to 15 PSI (103.42 kPa) across dual barbed ports.

Why Choose This Part

The integrated signal conditioning eliminates the need for external op-amps, reducing PCB footprint and design complexity. Its 1.5% accuracy and calibrated temperature compensation ensure reliable performance across the -40 C to 125 C operating range.

Applications

HVAC Airflow Monitoring
Measuring differential pressure across filters or within ducts to monitor system efficiency.
Medical Ventilators
Providing precise airflow and pressure feedback for respiratory care equipment.
Industrial Process Control
Monitoring pressure drops in pneumatic lines and gas delivery systems.
Environmental Monitoring
Differential sensing for leak detection and cleanroom pressure maintenance.

Getting Started

To interface with this sensor, provide a stable 5V supply and connect the analog output to a microcontroller ADC. For prototyping, the dual 3mm (0.12 inch) barbed ports can be secured using standard flexible tubing. Ensure the PCB layout accounts for the top-port SOIC package orientation to prevent port occlusion.
