Media resistant relative pressure sensors like the MS5547 from AMSYS 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 ... +2200 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 5 mbar.
Suitable for reflow soldering
The biocompatible plastic housing is sealed with a 2 x 1 mm² O-ring and the overall size of the sensor is only 4 x 4 x 4.4 mm³. 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.
