Incorrect mounting
The device can be damaged, destroyed, or its functionality impaired through improper
mounting.
● Before installing ensure there is no visible damage to the device.
● Make sure that process connectors are clean, and suitable gaskets and glands are used.
● Mount the device using suitable tools. Refer to the information in Technical data
(Page 191).

Device damage caused by impact at temperatures below -20 °C.
● Make sure that the line and cable entries are protected from impacts.
5.2 Installation (except level)
5.2.1 Installation configuration
The pressure transmitter can be configured above or below the pressure sampling point. The
recommended configuration depends on the aggregate state of the process medium.
Installation configuration for gases
Install the pressure transmitter above the pressure sampling point.
Lay the pressure tubing with a constant gradient to the pressure sampling point, so that any
condensation produced can drain in the main line and thereby avoid corruption of the measured
values.
Installation configuration for vapor and liquid
Install the pressure transmitter below the pressure sampling point.
Lay the pressure tubing with a constant gradient to the pressure sampling point so that any
gas pockets can escape in the main line.
