MS5547: digital gel-protected gauge pressure sensor

This inexpensive yet robust design is now also available in a version for relative pressure up to two bar.

Media resistant gauge pressure sensors like the MS5547 are used in very different areas, such as in medical technology, but also in e-cigarettes. Both a biocompatible silicone gel and a particularly robust Flour gel are available.

The new MS5547 offers maximum accuracy in the range of –200 ... +2,200 mbar. The pressure and temperature data can be read out in 24-bit format via I²C or SPI. The 11 correction coefficients stored in the sensor enable external compensation down to an accuracy (TEB) of less than five mbar.

The biocompatible plastic housing is sealed with a 2 x 1mm² O-ring and the overall size of the sensor is only 4 x 4 x 4.4mm³. The sensor is exposed to atmospheric pressure through a little hole in the ceramic under the sensor.
The sensors are suitable for reflow soldering and are of course RoHS and REACH compliant.
