Vibrocont SHM-300 is a point level switch for liquids. The Vibrocont SHM-300 is especially designed for food & beverage applications where hygienic requirements are requested. The Vibrocont SHM-300 is used for overfill prevention or pump dry-run protection preferably in storage tanks, mixing vessels and pipes.

– Smallest vibronic sensor
– Continuous self-monitoring
– Reliable switching independent of media properties
– No calibration or adjustment
– Plug & play
