Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
Only use the pressure transmitter if it is in perfect condition with respect to safety.
6.1 Mechanical mounting
The sealing faces at the instrument have to be undamaged and
■
clean.
When screwing the instrument in, the force required to do this must
■
not be applied through the casing, but only through the spanner flats
provided for this purpose and using a suitable tool.
The correct torque depends on the dimensions of the process
connection and the gasket used (form/material).
Do not exceed the following tightening torque:
max. 30 Nm
When screwing in, do not cross the threads.
