2. Design and function
2.1 Functional description
Level sensors work on the float principle with magnetic transmission.
A permanent magnet built into the float  triggers, with its magnetic
field, the resistance measuring chain built into the guide tube. The entire
assembly corresponds to a 3-wire potentiometer circuit. The float 
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 finely-stepped due to the contact separation of the
resistance measuring chain and is thus virtually continuous.
