Level limit switch Series RN 4000 Technical information / Instruction manual Applications The ROTONIVO is an electromechanical Level limit switch and is used for level monitoring of bulk goods. The units can be delivered with Ex-approvals for use in Hazardous Areas. Selected applications: The ROTONIVO is normally screwed into the lateral container wall so that it is level with the filling height to be registered and monitored. The device can also be mounted from the top of the container. In this case an extension piece is used to mount the probe level with the height to be registered (full detector)....

Level limit switch Series RN 4000 Technical information / Instruction manual A measuring vane is driven by a synchronous motor. The bearing of the motor inside the housing allows it to swing. The motor is fixed to a switching lug. Signal output delay The version "universal voltage" and "PNP" has an integrated adjustable delay for the signal output. If the vane is uncovered, a spring pulls the motor and switching lug to the left position (figure 1). Option fail safe alarm With the fail safe alarm it is possible to recognize a fault of the unit in time and to initiate an alarm relay. The following...
