SDP816-125PA

The SDP816-125PA from Sensirion is a differential pressure sensor with analogue output and 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 an analogue ratiometric voltage output which is configurable to linear or square root by a separate pin. 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.
