Vibration level switch
Vibranivo® - VN 4020
Application area
The vibrating fork Vibranivo® VN 4020 is used in storage and process vessels as a full, demand, and empty detector in many dry and free flowing bulk solids. The short extension enables the probe to withstand high mechanical loads. Its stainless steel probe extension allows the vibrating fork to work in a variety of aggressive environmental conditions.
