4. Design and function
4.1 Description
By means of a sensor element and by supplying power,
the prevailing pressure is converted into an amplified
standardised electrical signal via the deformation of a
diaphragm. This electrical signal varies in proportion to the
pressure and can be evaluated accordingly.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the pressure transmitter for any damage that may
have been caused during transportation.
Obvious damage must be reported immediately.
