Rotary blade level indicator for vertical mounting.
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. with a bulk density between 0.01 to 2 t/m3. Although the characteristics of the product, humidity, 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 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 off 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.
