Rotary Paddle Level Switch DMS-XLT–20FH

High-Quality Rotary Paddle Level Switch

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 infiltration 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


  • Used for detecting material level of warehouse, vessel, bin and tank. The material level switch can prevent warehouse flooding, tank jam and ware house empty so as to reduce flooding, material waste and standby time.
  • It is also suitable for plastic, food, chemical industry, mineral iron, material and other solid matter.
