Specification
1.1 Intended use
The rotary blade level indicator IR observes the filling level as a
limit switch. It can be used as indicator for dusty and powdery,
granulated and grainy bulk goods and are appropriated due to the
range of models and blades to control the level of bulk solids like
dust, flour, grain, sand, plastic, etc.

conductivity, grain size, etc. change, any adjustment is needed
These devices are used to control the level in silos, containers,
bunkers and they can be installed horizontally or vertically. For
vertical mountings there are rope shafts up to 10 m that could be
made depending on the product to control.
The rotating measuring blade, projecting into the silo or container,
is driven by a gearmotor. If the bulk material reaches the
measuring blade, the rotation will be hindered and it will be
stopped. The return torque turns the pivoted motor from its end
position and actuates the signal switch. A second switch turns the
motor off.
If the filling level of the bulk material sinks, the blade becomes
freely again and a spring will turn the motor back into its original
end position. Thereby the motor will be turned on again and the
signal switch will be switched back.
