A high resolution and high accuracy differential pressure sensor used for building science applications.

 

The SDP1000-L025 differential pressure sensors for air covers -62Pa to +62Pa. The SDP1000 is mounted in a rugged housing and is equipped with a standard audio jack for easy usage with SMT data acquisition units.The SDP1000 differential pressure sensor features a unique dynamic range, zero offset and unsurpassed long term stability. This makes it an ideal fit for mobile applications where it is used in different orientations.

 

Although the output of the differential pressure sensor is analog, the internal linearization and temperature compensation are performed digitally. This results in a superior accuracy, outstanding resolution (up to 0.05 Pa), and lowest temperature dependence.

  • The leading performance is based on Sensirion’s proprietary CMOSens® sensor technology which combines the sensor element with amplification and A/D conversion on one single silicon chip. The differential pressure is measured by a thermal sensor element. In contrast to other thermal differential pressure sensors only a very small amount of air is required. This leads to a reliable operation even under harsh conditions. In comparison to membrane based sensors the SDP1000 differential pressure sensor show an extended measurement range, better offset stability and improved reproducibility even at low pressure ranges. In addition the SDP1000 is robust against pressure bursts and shows no sensitivity to the mounting orientation.

     

    The Differential Pressure Sensor is based on a proprietary technology used to reduce output offset and common mode errors. Output offset errors due to change in temperature, warm-up instability, and position sensitivity are significantly reduced when compared to conventional compensation methods. The sensor uses a silicon, micro machined stress concentration enhanced structure to provide a very linear output to measured pressure.
