{ } Items in curved brackets are optional extras for additional price.
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 9 „Troubleshooting".
 Open pressure connections only after the system is without pressure!
 Observe the ambient and working conditions outlined in section 7 „Technical
data".
Warning
Please make sure that the pressure transmitter is only used within the over-

load threshold limit at all times!
When touching the pressure transmitter, keep in mind that the surfaces of
the instrument components might get hot during operation.
