Key Specifications/Special Features:

  • Vibrating rod level switch is an economical choice in level detection of powders and bulk solids
  • VRLS utilizes a piezoelectric crystal that vibrates the rod at a natural frequency
  • Once the rod comes in contact with the material, the vibration will be dampened and the switch will change state
  • Once the rod is uncovered by the material, the switch will revert to its normal state
  • Perfect for silo or hopper applications, its probe design allows for self-cleaning, ensuring no build-up or bridging of material and accurate detection
  • Sensitivity is adjustable for detection ranging from large granular material to small powders with low bulk densities
  • Fail safe mode can be set for failure on high level or failure on low level using a selector switch in the enclosure
  • Service: dry powder or bulk materials compatible with wetted materials
