Rotary paddle level switch

Rotonivo® - RN 3001

Application area

The rotating paddle detector Rotonivo® RN 3001 is used in storage and process vessels as a full, demand and empty detector in all bulk solids. It can be configured for process temperatures up to +1100°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.
