SENSIRION SDP810-125PA Datasheet & Stock

The SDP810-125PA 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.
