Rotary paddle level switch

Rotonivo® - RN 3005

Application area

The rotating paddle detector Rotonivo® RN 3005 is used as a full detector in tank and container loading bellows for all bulk materials. Buildup or a dust-intensive process environment does not in any way affect the accuracy of the measurement results of the level indicator. Due to its compact design, it can be installed in a space-saving manner in the loading sets.
