Differential Pressure Sensors Add More Addresses

Sensirion introduces variations of the SDP800 differential pressure sensor series, the SDP801-500Pa and SDP811-500Pa. Additions to the portfolio offer an additional I2C address that enables the connection of two sensors to the same I2C bus. The SDP800 series are targets cost-sensitive applications like water heaters, burners, VAV controllers, and medical respiratory applications. Sensors of the SDP800 series are said to be easy to integrate due to a proven form factor.

 

The SDP800 sensors offer reliable repeatability and a measurement speed up to 2 kHz. The fully calibrated and temperature-compensated sensors are available in versions that differ in pressure range, pneumatic connection, output signal, and now also different I2C addresses. They are based on Sensirion's patented CMOSens Technology. Differential pressure is measured by a thermal sensor element using the flow-through principle. They come with no zero-point drift and allegedly outperform traditional piezo-resistive membrane sensors in terms of sensitivity at low differential pressures, offset drift and hysteresis. The sensors are not susceptible to shocks and temperature cycles. For more details, peruse the SDP800 series datasheet.
