Rotary paddle level switch

Rotonivo® - RN 6004

Application area

The Rotonivo® RN 6004 rotating paddle switch functions in bulk solids processing plants as overfill protection and empty run protection in storage and process vessels. The full, demand and empty detector can be configured for process temperatures up to +600°C and a process overpressure up to 10 bar and is mechanically very resilient. The RN 6004 offers more space for wiring due to the larger housing, flameproof enclosures for use in the GasEx area and SIL2 certification.
