LD 60/ LD 61 Vibrating Fork Level Switch

The LD60/LD61 is a level switch using the vibrating fork technique. It is a robust and compact switch for the measurement of liquids and solids (LD60). Some typical applications are:

  • Pump control
  • Open and pressurized tanks
  • Tanks with mechanical agitation
  • Open channel and pipe empty/full detection
  • Distillation columns
  • Evaporators
  • Chemical dosing tanks


  • No moving parts
  • Not affected by temperatures or pressure changes
  • Suitable for liquids with viscosity up to 10,000 cSt.
  • Minimum density 0.6 kg/l
  • Detection of solids (powders) only LD60
  • Corrosion resistant materials
  • Maintenance free
  • Integral electronics
  • Selection of normally open or normally closed operation
  • LED status indication (bicolor)
  • Functions test with external magnet
  • Connections:
  • Thread: BSP / NPT
  • Flange: DIN / ANSI
  • Sanitary: Clamp, DIN 11851
  • Wide range of sensor lengths
