The new sensor products are based on Sensirion’s innovative CMOSens technology, which integrates a sensor element and all the necessary signal conditioning electronics – including analogue and digital signal processing – on a single tiny CMOS chip.
The technology is well proven and is perfectly suited for high-quality and cost-sensitive volume production.
The SDP800 series sensor element, which uses flow-through technology to measure differential pressure, together with the on-chip signal processing and digital calibration, delivers high accuracy with no offset drift, right down to the lower end of the measurement range.
These new CMOSens-based sensors largely overcome the limitations in offset drift and accuracy of traditional static or dynamic differential pressure sensors commonly used in HVAC applications.
In conjunction with low-cost advantages, this makes them an attractive alternative for measuring differential pressure and airflow volumes in modern HVAC systems.
Available in the SDP800 series are the 4-pin +/–500 Pa SDP800-500PA, and the 4-pin +/– 125Pa SDP800-125PA.
As well as offering characteristics including high reliability, long-term stability and an excellent signal-to-noise ratio, the sensors also feature a two-wire digital interface for easy connection to microcontrollers.
In addition, the Sensirion EK-P5 evaluation kit enables easy and fast sensor evaluation via PC test software, connected via USB cable.
