Rotary paddle level switch
Rotonivo® - RN 3003
Point level measurement
Solids
bulk weight > 15 g/l (> 0.9 lbs/ft3)
The rotating paddle detector Rotonivo® RN 3003 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 +250°C and process overpressure up to 10 bar and is mechanically extremely resilient. Buildup or a dust-intensive process environment does not in any way affect the accuracy of the measurement results of the level indicator
Mechanically extremely resilient for heavy and coarse-grained bulk materials
Simple, reliable and maintenance-free all-rounder in bulk solids applications
Plug and play level limit switch without calibration
