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.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
