Vibration level switch OPTISWITCH 5100 C – Version with plastic housing

The OPTISWITCH 5100 is a vibration level switch for liquids in process applications. It is a universal and reliable device for limit level detection in vessels. It detects low or high level and is used for overfill, dry-run or pump protection. Installations in pipelines are also possible.

Product highlights

  • Large choice of process fittings and housing materials
  • Optional adapter for high temperatures up to +250°C / +482°F
  • Outputs: relay, transistor, 2-wire, NAMUR or contactless electronic switch
  • Optional gas-tight lead-through for toxic gases
  • Suited for hazardous and non-hazardous areas
  • SIL2-compliant

Typical applications

  • Pump dry-run protection
  • Limit and overfill detection
  • Liquid detection in pipes
  • SIL2 loops / Safety-related Safety Instrumented Systems (SIS)
