8.2 Float
The float is a key 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 are available to order separately. Other float
types and materials are available on request.
The density and magnet position of floats of the same type may vary
slightly, in which case readjustment may be required.
All floats are also suitable for use at a pressure of -1 bar (vacuum).

*) above 50 °C the maximum operating pressure decreases
Pressure resistance is guaranteed for undamaged floats only. Even the most
minor 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
deterioration in pressure resistance.
