The level sensor measures the
filling level of the steam boiler.
The evaluation takes place using
capacitance with a level control,
which is integrated into the controller.
Its function is not affected by an
insulating layer of chalk or similar
materials. The electrode should only
be replaced as a preventive measure
during a major inspection because the
evaluation is free of wear.
