Vibration level switch

Vibranivo® - VN 5050

Application area

The Vibranivo® VN 5050 vibrating fork is used in storage and process vessels as a full detector in dry and free flowing solids. The level probe can be flexibly configured up to a length of 7000 mm and puts the switching point where the application needs it. The vibrating fork sensor boom with optional cable extension is the safe solution in applications where lateral forces act on the vibrating fork. The VN 5050 offers more space for wiring due to the larger housing and additionally a flameproof design for use in GasEx areas.
