Vibration level switch

Vibranivo® - VN 6050

Application area

The Vibranivo® VN 6050 vibrating fork is used in storage and process vessels as a full detector in many dry and free flowing bulk solids. The tuning fork sensors can be flexibly configured up to a length of 20000 mm and bring the switching point where the application needs it. Due to its high sensitivity, the point level probe is particularly suitable for very light bulk solids. The VN 6050 offers more space for wiring due to the larger housing and additionally a flameproof version for use in the GasEx area.
