Rotary paddle level switch

Rotonivo® - RN 6003

Application area

The Rotonivo® RN 6003 rotating paddle switch is installed in storage and process containers as a full, demand and empty switch in the entire bulk solids spectrum. It can be configured for process temperatures up to +250°C and up to 10 bar process overpressure and is mechanically extremely resilient. The RN 6003 offers more space for wiring due to the larger housing, flameproof enclosures for use in the GasEx area and SIL2 certification.
