Differential pressure sensor in the 0 to 500 Pa range has a zero-point accuracy of 0.2 Pa

Sensirion's SPD500 low-cost positive differential pressure sensor is a fully calibrated and temperature compensated sensor suitable for measuring differential pressure in the range of 0 to 500 Pa.

The device is able to detect even minute pressure differences below 10 Pa. With a zero-point accuracy of 0.2 Pa, the sensor offers both low cost and excellent specifications. Integration of the sensor element and signal conditioning circuitry on a tiny CMOS silicon chip enables noise-free and precise amplification and digitization of sensor signals. As a result, the differential pressure sensor achieves extremely high measurement accuracy and outstanding long-term stability. The underlying CMOSens technology allows the microchips to be produced in large volume at competitive end-user prices with consistently high quality. With an accuracy of 4.5% of the measured value, zero-point stability and I²C digital output, the new differential pressure sensor is especially suitable for applications in the HVAC industry. Like all other sensors in the SPD600 series, the new sensor is available in two different versions. The SDP500 is designed to be screwed directly to a manifold with O-ring sealing, while the SDP510 is designed for tube connections.
