3.1 Mechanical Installation
Before starting operation, check the process connection carefully for leaks under pressure.
Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
The process connection determines the permissible process pressure. Operating the de-
vice beyond its nominal pressure limit, e.g. clamp-connections, requires specially designed
and approved mounting elements.
3.2 Electrical Connection
Complete the mechanical installation before you connect the device electrically.
Set up all electrical connections while the voltage supply is switched off.

Operation
During operation, take care that the device remains within its intended pressure and tem-
perature ranges. No other monitoring is necessary.
Permissible media temperature:
-
50…200 °C
Permissible ambient temperature:
-
40…85 °C
When supplied with a transmitter, the permissible ambient temperature is reduced to -
20…80 °C.
Restricted ambient conditions may apply in explosion protected environments (see
XA_001).
4.1 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is
maintenance-free. However, we recommend an annual recalibration of the device.
In the event of a device malfunction, you can only replace the measuring insert respective-
