Instructions for installation (except level)
Requirements
Note
Compare the des
ired operating data with the data on the nameplate.
Please also refer to the information on the remote seal if this is fitted.
Note
Protect the pressure transmitter from:
•
Direct thermal radiation
•
Rapid temperature fluctuations
•
Severe soiling
•
Mechanical damage
• Direct sunlight
The installation location is to be as follows:
● Easily accessible
● As close as possible to the measuring point
● Vibration-free
● Within the permitted ambient temperature values
Installation configuration
The pressure transmitter may in principle be configured above or below the pressure tapping point. The recommended
configuration depends on the aggregate state of the medium.
Installation configuration for gases
Install the pressure transmitter above the pressure tapping point.
Lay the pressure tubing with a constant gradient to the pressure tapping 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 tapping point.
Lay the pressure tubing with a constant gradient to the pressure tapping point so that any gas pockets can escape in the
main line.
