Product Overview

The Sensirion SDP810-500PA Digital Differential Pressure Sensor, part of the SDP800 series, features a tube connection package designed for high-precision pressure measurement. Supporting ±500Pa bidirectional pressure range, it integrates Sensirion’s patented CMOSens® technology, offering zero offset drift, temperature compensation, and smart averaging. With an IC interface for easy data communication, it is ideal for precise pressure monitoring and flow control in industrial automation, medical devices, and HVAC systems.

Key Features

• High Precision & Stability: Achieves 0.1Pa zero-point accuracy, 3% span accuracy, and 0.05Pa zero-point repeatability, ensuring reliable long-term measurements with <0.05Pa/year offset stability.
• Wide Temperature & ESD Resistance: Operates from -40°C to +85°C with built-in temperature compensation, and withstands 2kV ESD (HBM), ensuring robustness in harsh environments.
• Smart Averaging & Fast Response: Supports continuous and triggered measurement modes with intelligent averaging, achieving <3ms response time (63%) to filter noise and capture dynamic pressure changes.
• Low Power Design: Consumes only 1μA in sleep mode, ideal for battery-powered devices, with configurable modes to balance accuracy and energy efficiency.
• Easy Integration & Compatibility: Standard IC interface (400kHz to 1000kHz) works with microprocessors, while the tube connection package enables easy integration into pipeline systems.

Technical Specifications

Typical Applications
