2. Design and function
2.1 Functional description
Level sensors work on the oat principle with magnetic transmission.
A permanent magnet built into the oat triggers, with its magnetic
eld, the resistance measuring chain built into the guide tube .The
entire assembly corresponds to a 3-wire potentiometer circuit. The oat
changes its height with the level of the medium it is monitoring.The
measured resistance signal is proportional to the level.The measure-
ment voltage is very nely stepped due to the contact separation of the
resistance measuring chain and is thus virtually continuous.

DANGER!
... indicates a directly dangerous situation resulting in
serious injury or death, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result
in serious injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result
in light injuries or damage to property or the environment, if
not avoided.
Information
... points out useful tips, recommendations and information
for ecient and trouble-free operation.
3.2 Intended use
Level sensors are used exclusively for monitoring the levels of liquid
media. The scope of application is dened by the technical performance
limits and materials.
■
The liquids must not have any large contamination or coarse particles
and must not have a tendency to crystallise. Ensure that the wetted
materials of the level sensor are suciently resistant to the medium
being monitored. Not suitable for dispersions, abrasive liquids, highly
viscous media and colours.
