Sensirion, the world's leading manufacturer of high-quality environmental and flow sensors, presents new product variants of the SDP800 differential pressure sensor series. The SDP801-500Pa and SDP811-500Pa complement the product portfolio with an additional I2C address that enables the connection of two sensors to the same I2C bus. The SDP800 series are the perfect fit for the most demanding yet cost-sensitive applications like water heaters, burners, VAV cotrollers and medical respiratory applications.

Product development of the SDP801-500Pa and SDP811-500Pa, new versions of the SDP800 series, is now complete and ready for high-volume production. With the new sensors, an additional I2C address is created.

Differential pressure sensors of the SDP800 series are the result of leading the market in air flow measurement for more than 15 years and are the reliable and advanced solution for the most demanding yet cost-sensitive applications. The sensors are easy to integrate into water heaters, burners, VAV controllers and medical respiratory applications due to its proven form factor.

The SDP800 sensors offer excellent repeatability and a measurement speed of 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.

Like all Sensirion differential pressure sensors, the SDP800 series is based on Sensirion's patented CMOSens® Technology. The differential pressure is measured by a thermal sensor element using the flow-through principle. Thanks to this, Sensirion's differential pressure sensors come with no zero-point drift and 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.
