Differential pressure sensor

20 April 2016 Test & Measurement

Measuring just 5 x 8 x 5 mm, Sensirion’s new SDP3x digital differential pressure sensor enables numerous integration and application possibilities, including for the measurement of air flows in medical technology or the consumer goods industry.

It measures differential pressure and is ideal for the measurement of mass flow in a bypass configuration.

Built on the latest generation of Sensirion’s CMOSens chips which integrate the sensor element and the evaluation circuit, the sensor boasts high accuracy, long-term stability and no zero-point drift. It also offers fast signal processing and response time, and includes various other digital functions such as multiple I²C addresses and interrupts.

The fully calibrated and temperature-compensated differential device is available as the SDP31 (digital with an I²C interface) and the SDP36 (analog output signal). Both versions measure a bidirectional flow range of up to 500 Pa, and are reflow solderable and available in a pick-and-place package on tape and reel for industrial manufacturing. During 2016, new products with extended measurement ranges and different features are set to be added to the SDP3x series.
