Weight
When designing your plant, take into account that the stated values (e.g.burst pres-
sure, over pressure safety) apply depending on the material and thread used.
The respective values for your mounting torque and maximum pressure please
find in the documentation of your high-pressure equipment supplier.
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".
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.
