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 amplied and standardised. The output signal is proportional to the measured pressure.
