If there is a risk of the cable probe touching the vessel wall during
operation due to product movements or agitators, etc., the measuring
probe should be securely fixed.
There is an inside thread (M8) in the gravity weight, e.g. for an eye-
bolt (optional).
Make sure that the probe cable is not completely taut. Avoid tensile
loads on the cable.
Avoid undefined vessel connections, i.e. the connection must be
either grounded reliably or isolated reliably. Any undefined change of
this requirement can lead to measurement errors.
If there is a danger of the rod probe touching the vessel wall, then the
probe must be fastened at the bottom end.
Keep in mind that below the fastening, a measurement is not possible.
