OPTISWITCH 3000 Series

Product Announcement from KROHNE Group

OPTISWITCH 3000 Series -Image

Vibration Level Switches for solids

  • Highly robust tuning fork
  • Insensitive to build-up
  • Set-up without filling
  • Detection of solids in water
  • Maintenance-free

Cement or aggregates are placed in interim storage in multiple chamber silos. When the chambers are filled, large quantities of dust are generated. Depending on the consistency of the aggregate, different material cones are formed and the product properties can change from filling to filling.
OPTISWITCH offers additional protection against overfilling the aggregate silo. The flexible suspension cable avoids mechanical strain caused by movements of the bulk solid. A filling is not necessary for setup. Because OPTISWITCH has practically no moving parts, it is not subject to wear.


  • OPTISWITCH 3100 C - Compact version
  • OPTISWITCH 3200 C - Version with suspension cable
  • OPTISWITCH 3300 C - Version with tube extension
