Rotary paddle level switch

Rotonivo® - RN 3002 - Rope

Application area

The rotating paddle detector Rotonivo® RN 3002 with rope extension is mainly used in storage and process vessels as a full detector in all bulk solids. Taking into account the tensile forces, it can also be used as a demand or empty detector. It can be configured for process temperatures up to +600°C and process overpressure up to 10 bar.  Buildup or a dust-intensive process environment does not in any way affect the accuracy of the measurement results of the level indicator.
