SENSIRION SDP816-500PA Analog CMOSens Differential Pressure Sensor with Tube Connection

Specifications

Product Introduction

The SDP800 sensor family is a series of digital differential pressure sensors designed for high-volume applications. These sensors measure the pressure of air and non-aggressive gases with high accuracy and no offset drift. They cover a pressure range of up to ±500 Pa (±2 inch H₂O / ±5 mbar) and deliver outstanding accuracy, even at the bottom end of the measuring range. The SDP800 Series features a digital 2-wire I2C interface, making it easy to connect directly to a microprocessor. The performance is based on patented CMOSens® sensor technology, which combines the sensor element, signal processing, and digital calibration on a small CMOS chip. The differential pressure is measured by a thermal sensor element using flow-through technology.
