OPTISWITCH 6500 C Microwave Level Switch
Brand: KrohneThe OPTISWITCH 6500 C is a level switch for level detection and dry-run protection for liquids and solids. Through its small and optimal sensor shape, the device is easy to clean and the risk of clogging of sticky products is minimised.
The device measures liquids such as water and beer and even viscous and sticky products such as honey or toothpaste. Dry media (sugar or flour) can be also measured.
The measurement is precise and not affected by the mounting position. Coating of the sensor or condensate is not detected.
The OPTISWITCH 6500 C is resistant to CIP and SIP agents.
Hygienic installation is possible with the comprehensive range of accessories.
Features- Process temperature -40° to 200° C (-40° to 392° F) (sliding connection)
- Insensitive to build up or foam
- Measures alternating media
- LED switching point indication through cover
- Hygienic switch entirely made of stainless steel
- Excellent for media separation
- No blockage of the pipeline
