Measuring low pressures cost effectively is always a tricky proposition. The MS4515 Series of pressure sensors is a ceramic-based, PCB-mount design that uses CMOS signal conditioning circuitry to create a low cost, high performance sensor. Units are available in various calibration ranges between 0-2” H2O up to 0-30” H2O.
The analog version, MS4515, has a ratiometric voltage output while the MS4515DO provides a 14-bit digital output for pressure and a 11-bit output for temperature in an I2C or SPI protocol.
Available with single or dual side ports, top ports or manifold mount in a gauge or differential configuration, the sensor has 1/8-in barbed pressure ports to mate securely with 3/32-in ID tubing.

2″ wc is a lot, i am looking for a differential pressure sensor starting at 50 Pa equal to 5 mm (about 3/16″!) – can you offer such with a digital output.
