9.2 Float
The float is an essential component of the level sensor that must be matched to the medium
in respect of density, pressure resistance and material durability.
The following floats are exchangeable and can be ordered separately. Other float types and
materials are available on request.
The density and magnet position of floats of the same type may vary slightly,
so that a readjustment may be necessary.
All floats can be used at a pressure of 1 bar (vacuum) up to the maximum
operating pressure.

*) above 50 °C the maximum operating pressure decreases
Pressure resistance is guaranteed for undamaged floats only. Even the most mi-
nor and invisible dents, which can occur if, for example, the float is dropped
from a bench onto a stone floor, are sufficient to cause a significant deteriora-
tion in pressure resistance.
