Installation
Installation conditions
• Moisture must not penetrate the housing when mounting the device, establishing the electrical
connection and during operation.
• Point the cable and connector downwards where possible to prevent moisture from entering (e.g.
rain or condensation water).
Influence of the installation
position
Any orientation is possible. However, the orientation may cause a zero point shift i.e. the measured
value does not show zero when the vessel is empty or partially full.

Mounting location
Pressure measurement
Pressure measurement in gases
Mount the device with shutoff device above the tapping point so that any condensate can flow into
the process.

Shutoff device
Pressure measurement in vapors
For pressure measurement in vapors, use a siphon. The siphon reduces the temperature to almost
ambient temperature. Mount the device with a shutoff device at the same height as the tapping
point.
Advantage:
only minor/negligible heat effects on the device.
Note the max. permitted ambient temperature of the transmitter!
