Rotary paddle level switch

Rotonivo® - RN 3004

Application area

The rotating paddle detector Rotonivo® RN 3004 is used in storage and process vessels as a full, demand and empty detector in all bulk materials. It can be configured for process temperatures up to +600°C and process overpressure up to 10 bar and is mechanically very resilient.  Buildup or a dust-intensive process environment does not in any way affect the accuracy of the measurement results of the level indicator.
