Vibration level limit switch for liquids

  • Designed for hygienic applications especially in the food industry - hygienic process connections and approvals available

  • CIP and SIP cleanability ensured - up to protection class IP69k

  • Designed according to highest requirements to quality and environmental sustainability, the self-monitoring Vibrocont SHM-300 offers safe switching also in case of power supply loss

  • Independent of changing media properties an accurate switching point is offered

  • A real plug & play sensor is offered without any need for adjustment even with changing media. Measurement is unaffected by conductivity, build-up, turbulence, flows or air bubbles

  • No calibration is required, no specific know-how or tools (e.g. software) necessary

  • Robust design made of stainless steel (316L) assures highest durability - no mechanically moved parts, free of maintenance

Application description

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.
