The new SDP600/610 is the first digital, dynamic differential pressure sensor for air and non-aggressive gases. Supplying a digital I2C output, it measures with highest sensitivity and accuracy even at low differential pressures (below 10 Pa). With its exceptional integration level and clever packaging, the sensor works with superb long-term stability and is available at an economical price.
The outstanding performance is a result of the dynamic measuring principle, in which the differential pressure is determined using intrinsic flow measurement. This is based on Sensirion’s patented CMOSens® technology, which combines the thermal sensor element, signal processing and digital calibration on a tiny microchip.
The fully calibrated sensor is available in two versions. The SDP600 is intend for a direct threaded connection to a pressure manifold via O-ring sealing, while the SDP610 is designed for a hose connection. SDP600 series is designed for high-quality mass production, which makes it a perfect fit for demanding OEM applications, e.g. in the medical technology and HVAC industries.
