Differential Pressure Sensors

Sensirion AG, 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 utilise 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. It offers 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. An evaluation kit is available for quick and easy testing of the digital SDP800 sensors.
