Rotating Paddle Level Switches

ProSense PLS series rotating paddle level switches are point level switches for dry, granular bulk solids. These switches operate by contact with the medium; if the paddle is stopped by the material, the motor’s position change operates switch contacts These level switches are available in three shaft lengths, plus a rope version that can be shortened in the field based on the application.


  • 100mm, 200mm, 300mm shaft lengths or 2000mm cuttable rope version
  • Operating voltages of 115VAC, 230VAC and 24VDC
  • SPDT relay output for PLC input or direct control of bulk solids handling equipment
  • Models with Factory Mutual (FM) certification for Dust Ignition Proof, Class II, III, Division 1, Groups EFG
  • Adjustable switching sensitivity can be set without tools and even during operation in non-hazardous areas
  • Optical shaft rotation monitoring for operational verification is visible with the device installed
