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 measurement voltage is very finely stepped due to the contact
separation of the resistance measuring chain and is thus virtually
continuous.
