CAUTION!
Prior to commissioning, the pressure sensor must be subjected to a visual
inspection.
Only use the pressure sensor 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 case, but only through the spanner flats
provided for this purpose and using a suitable
tool.
For the installation point, the valid values for
tightening torque and maximum pressure
should be taken from the high-pressure pipe
supplier's documentation.
■
When screwing in, do not cross the threads.
6.2

Electrical mounting

■
The instrument must be grounded via the process connection.
■
Use the pressure sensor with shielded cable, and ground the shield on at least one
end of the lead, if the lines are longer than 30 m (3- or 4-wire) or leave the building.
■
Select a cable diameter that matches the cable gland of the plug. Make sure that the
cable gland of the mounted plug has a tight fit and that the seals are present and
undamaged. Tighten the threaded connection and check that the seal is correctly
seated, in order to ensure the ingress protection.
■
For cable outlets, make sure that no moisture enters at the cable end.
■
Observe the specifications in accordance with chapter 3 "Specifications".
