SDP816-500PA Sensirion

Datasheet SDP8xx-Analog Differential Pressure Sensor with Analog Output Configurable analog output Calibrated and temperature compensated Excellent repeatability, no drift Product Summary The SDP800 sensor family is Sensirions series of differential pressure sensors designed for high-volume applications. The sensors measure the pressure of air and non-aggressive gases with superb accuracy and no offset drift. The sensors cover a pressure range of up to 500 Pa (2 inch H O / 5 mbar) and deliver outstanding accuracy, also at the lower end of the 2 measuring range. The SDP800 features an analog ratiometric voltage output, which is configurable to linear or square root by a separate pin. The outstanding performance of these sensors is based on Sensirions patented CMOSens sensor technology, which combines the sensor element, signal processing, digital calibration and analog output on a small CMOS chip. The differential pressure is measured by a thermal sensor element using flow-through technology. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications. Benefits of Sensirions CMOSens Technology High reliability and long-term stability Best signal to noise ratio Industry-proven technology with a track record of more than 15 years Designed for mass production High process capability Content 1.

Note that the effect of output voltage integral non linearity and output voltage noise on accuracy is highly dependent on the output configuration (linear or square root). 6 For more information about temperature and pressure compensation consult the selection guide in the differential pressure download center on our website. www.sensirion.com Version 1 March 2018 2/8
