Vibration level switch

Vibranivo® - VN 2030

Application area

The vibrating fork Vibranivo® VN 2030 is used in storage and process vessels as a full, demand, and empty detector in many dry and free flowing bulk solids. Due to its high sensitivity, the probe is particularly suitable for use in very light bulk solids. The high surface quality of the stainless steel probe also makes it ideal for use in applications with hygienic requirements.
