3.2 Intended use
Float switches with external chamber are used exclusively for
monitoring the levels of liquid media. The scope of application is
defined by the technical performance limits and materials.
■
The liquids must not have any large contamination or coarse
particulates and must not have a tendency to crystallise. Ensure that
the wetted materials of the float switch are sufficiently resistant to
the medium being monitored. Not suitable for dispersions, abrasive
liquids, highly viscous media and colours.
■
This instrument is not permitted to be used in hazardous areas! For
these areas, float switches with approval (e.g. in accordance with
ATEX) are required.
