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