RS Components introduces highly integrated CMOS-based differential air pressure sensors from Sensirion for building automation applications

Stable, highly accurate differential pressure sensors, based on innovative CMOSens® technology, target heating, ventilation and air-conditioning (HVAC) systems


Johannesburg, South Africa, 7 April, 2017 - RS Components (RS), the trading brand of Electrocomponents plc (LSE:ECM), the global distributor for engineers, has announced availability of the SPD800 series of CMOS technology digital and analogue differential pressure sensors from Sensirion. Targeting high-volume applications, the sensors have been designed to measure the pressure of air and non-aggressive gases and deliver accurate and stable results covering a range of up to +/–500 Pa (+/– 5 millibars or +/– 2 inches of water), even at very low differential pressures.


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.
