Installing/mounting
5.2 Installing
Lay the pressure tubing with a constant gradient to the pressure sampling point so that any gas
pockets can escape in the main line.
Mounting location
Verify that the mounting location meets the following conditions:
● Accessible
● Close to the measuring point
● Vibration-free
● Within the permitted ambient temperature values
Protect the pressure transmitter from:
● Direct heat radiation
● Rapid temperature fluctuations
● Heavy contamination
● Mechanical damage
● Direct sunlight
Requirement
● You have compared the desired operating data with the data on the nameplate.
● You have adhered to the information on the remote seal during its installation.
Procedure
1. Attach the pressure transmitter to the process connection.
Use an appropriate tool (e.g. open-ended wrench with width across flats 36). Otherwise, the
measuring cell may be damaged.
2. Turn only on the key area above the process connection.
Caution: If you turn the pressure transmitter on the housing, the measuring cell may be
damaged.
