wetted parts.

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“.

 Open pressure connections only after the system is without pressure!  Observe the ambient and working conditions outlined in section 7

Warning

„Technical data.

 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.

Caution

8. Adjustment of zero point / span (only for pressure transmitter with clamping nut)

We do not recommend to adjust the span potentiometer. It is used for adjustment ex factory and should not be adjusted by you unless you have adequate calibration equipment at your disposal (at least three times more accurate than the instrument being tested).
