Displacement level indicator with plane mounting flange.

The level indicador observes the filling level as a limit switch in silos and vessels or control the flow and obstructions in tubes, pipes, conveyors, etc.

There are models with flexible round plates to facilitate the mounting in the round surfaces.

The rod sensor must to be exposed to the material. The bulk goods, being dumped beside the rod, move the rod. This movement activates the switch.

These models have a regulation system by a spring that allows the adjusment of the sensitivity. Tightening the regulation nut to reduce the sensitivity and increase the strain of the material to activate the microswitch. Clockwise insensitive.

Drill a Ø 30 hole in the wall of the silo or vessel, place the rod and mount the indicator using screws, rods, fasteners or nuts M6 making sure of the correct position of the rod.

The standard length of the rod is 115 or 150 mm depending on the model. If it is necessary, the rod can be cut to leave at the desired lenght. To control the flow in pipes, the rod must be with a minium distance of 10 mm of the bottom of the pipe and must be placed with enough distance to prevent the signal activation with the normal flow.


Approximate measures given in mm.
