Rotary paddle level switch

Rotonivo® - RN 3002 strengthened rope version

Application area

The Rotonivo® RN 3002 rotating paddle detector with strengthened rope version is used in storage and process vessels mainly as a demand and empty detector in bulk solids measurement. During application, tensile forces due to the rope overlap must be taken into consideration. These amount to a maximum of 28 kN. Process temperatures up to +600°C and a process overpressure up to 10 bar can be flexibly configured. The measurement results of the level sensor are insensitive to adhering material as well as to dust generation. Overfill protection and no-load protection are guaranteed for the long term.
