4. Design and function

4.1 Description
The prevailing pressure is measured at the sensor element through the deformation of a diaphragm. By supplying
power, this deformation of the diaphragm is converted into an electrical signal. The output signal from the pressure
transmitter is amplified and proportional to the prevailing pressure.
