SENSIRION SDP810-500PA Pressure Sensor, Differential, -500 Pa, 500 Pa, 2.7 V, 5.5 V, SIP

The SDP810-500PA from Sensirion is a digital differential pressure sensor with tube connection. It is designed for high volume applications. The sensor measures pressure of air and non-aggressive gases with superb accuracy and no offset drift. It delivers outstanding accuracy at bottom end of measuring range. The SDP800 features a digital 2-wire interface which makes it easy to connect directly to a microprocessor. The outstanding performance of this sensor is based on Sensirion�s patented CMOSens sensor technology which combines sensor element, signal processing and digital calibration on small CMOS chip. The differential pressure is measured by a thermal sensor element using flow through technology. The well proven CMOS technology is suitable for high quality mass production and it is ideal choice for demanding & cost sensitive OEM applications. It is also in HVAC, gas boilers, pellet stoves and fuel cells, filter monitoring, VAV control, heat recovery.
