Paddle Level Switch

Paddle | Level Switches

The drive device is a micromotor, and the transmission shaft is in contact with the clutch. When it does not make touch with the material, the motor continues to run normally; when the blade makes contact with the material, the motor stops operating; the testing device outputs a contact signal, cuts the power, and the rotary stops in the meantime. When the material progressively falls down, the pressure on the blade disappears, and the testing equipment returns to its previous state thanks to the torsion spring. Torsion could be controlled by varying the material's gravity.


  • Detection of loose solid objects utilizing spinning blade technology
  • The finely integrated mechanical seal prevents dust ingress along the axis.
  • When the blade is overworked, the unique elastically clutch structure allows for automated protection of electrical machinery.
  • Complete mechanical and electrical separation construction that does not need to be demolished and is simple to maintain
  • Low-density mediums can benefit from special blades.
  • Use of the connecting method, simple to install


  • The wire entrance of the junction box should be facing downward, and the screw nut should be securely tightened.
  • The power supply must match the power indicated on the Rotary Paddle Level Switch.
  • The load in the line should be proportional to the switch's contact capacity.
    on reduce impaction on the vane and fault action, the switch should not be installed under the solid feed inlet; if this cannot be avoided, please install a protective shield on the vane as shown in the drawing. The minimal distance between the protective shield and the body is 150mm.
