Overview

The SDP800-500PA is a high-performance differential pressure sensor designed for high-volume applications, offering a measurement range of -500 to 500 Pa (-0.07 to 0.07 PSI). Based on CMOSens technology, it provides excellent accuracy and long-term stability without zero-point drift, making it ideal for demanding mass flow and pressure monitoring tasks.

Why Choose This Part

This sensor features 16-bit resolution and is fully temperature compensated, ensuring reliable performance across a -40C to 85C range. Its I2C interface and low 3.8mA typical run current simplify integration into low-power embedded systems while maintaining high repeatability.

Applications

HVAC Airflow Monitoring
Precise measurement of filter pressure drops and VAV box control for efficient building climate management.
Medical Ventilation
Monitoring respiratory gas flow and airway pressure in medical devices with high sensitivity at low pressures.
Burner Control
Optimizing air-to-fuel ratios in gas boilers and heating systems through accurate differential pressure feedback.
Process Automation
Ensuring consistent airflow and pressure levels in industrial pneumatic and manufacturing systems.
