When designing your plant, take into account that the stated values (e.g.burst pressure, over
pressure safety) apply depending on the material, thread and sealing element used.

Functional test

The output signal must be proportional to the pressure. If not, this might point to a damage of the diaphragm.
In that case refer to chapter 10 „Troubleshooting".
WARNING!
Open pressure connections only after the system is without pressure!
