The Sensirion SDP3x differential pressure sensors are designed for high-volume applications where small size is a key requirement. They build on the next-generation CMOSens® sensor chip and provide fast measurement speeds with excellent accuracy and long-term stability. The devices are calibrated and temperature compensated, and operate from a 3.3V supply.
The SDP31 Digital sensor (123-7131) features extended functionality, such as smart averaging, multiple temperature compensation modes, configurable I2C address and interrupts.
The SDP36 Analogue sensor (123-7132) has a ratiometric output signal which is configurable; different measurement speeds, output curves and temperature compensations can be selected during use.
