Sensirion, the world’s leading manufacturer of high-quality flow and environmental sensors, presents the new differential pressure sensors of the SDP800 series. The sensors are the result of more than 15 years of experience in measuring air flow to millions of HVAC systems, car engines and patients. They consequently utilize the successful features of the SDP600 differential pressure sensor and come in the same proven housing, which enables easy integration. The next generation chip combines outstanding accuracy and long-term stability with extended functionality and higher measurement speed at even lower cost. Thus, the new SDP800 is the reliable and advanced solution for the most demanding, but cost-sensitive HVAC applications, such as VAV controllers and burners.
The new differential pressure sensors of the SDP800 series offer excellent repeatability and measurement speed up to 2 kHz. The fully calibrated and temperature-compensated sensors are available in numerous versions that differ in pressure range, pneumatic connection and output signal. Whereas the analog version provides a configurable analog voltage output, the digital version features different measurement modes, smart averaging functions and multiple I2C addresses. Both versions come with either 125 Pa or 500 Pa bidirectional pressure range and provide a manifold or tube connection.
Like all Sensirion differential pressure sensors, the SDP800 series is based on Sensirion’s patented CMOSens® Technology, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The differential pressure is measured by a thermal sensor element using the flow-through principle. Thanks to this, Sensirion’s CMOSens® 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, as well as position sensitivity, shock resistance and temperature variations.
An evaluation kit is available for quick and easy testing of the digital SDP800 sensors. This EK-P5 evaluation kit consists of a SDP810 sensor that is easily plugged into a PC via an USB cable. With the help of the software available online for download, the differential pressure sensor can be tested under realistic conditions by following the simple installation steps. The kit can be purchased directly from Sensirion distributors: www.sensirion.com/distributors
