Installation conditions

• Moisture must not penetrate the housing when mounting the device, establishing the
electrical connection and during operation.
• Do not clean or touch process isolating diaphragms with hard and/or pointed objects.
• Do not remove process isolating diaphragm protection until shortly before installation.
• Always tighten the cable entry firmly.
• Point the cable and connector downwards where possible to prevent moisture from
entering (e.g. rain or condensation water).
• Protect housing against impact.
• For devices with gauge pressure sensor, the following applies:
NOTICE
If a heated device is cooled in the course of a cleaning process (by cold water, for
example), a vacuum develops for a short time causing moisture to penetrate the
sensor via the pressure compensation element (1).
Device could be destroyed!
‣
In the event of this happening, mount the device in such a way that the pressure
compensation element (1) is pointing downwards at an angle or to the side, if possible.

Influence of orientation

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.
