In accordance with EN 61326-1, in case of outdoor installations, faults caused by surge voltages must be considered.
To protect the instrument, it must be connected using a shielded cable. The shield of the cable must be connected on
at least one side to ground or a suitable reference potential.
Alternatively, a suitable external measure to protect against surge voltages has to be provided.

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.
