OPTISWITCH 3100 C – Version with plastic housing

Vibration level switch OPTISWITCH 3100 C – Version with plastic housing

The OPTISWITCH 3100 is a compact vibration level switch suitable for solids. It can be used for applications with a low density (e.g. aerosol) or for solid detection (e.g. in the water of sedimentation tanks at hydro-electric power stations).

Product highlights

  • Abrasion resistant and highly robust design
  • Simple setup without product
  • Unaffected by changes of product properties (maintenance-free)
  • Optional version to detect solids in water
  • Remote housing up to 25 m / 82 ft

Typical applications

  • Silos with light bulk goods
  • Limit and overfill detection
  • Detecting solids in water
