Vibration level switch

Vibranivo^® - VN 1020

Point level measurement, Interface level measurement
Solids
bulk weight > 50 g/l (> 3 lbs/ft3)

Application area

The vibrating fork Vibranivo^® VN 1020 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. The high surface quality of the stainless steel probe also makes it ideal for use in applications with hygienic requirements.

Your benefit

Maintenance-free sensor for use in many bulk materials
Extension is completely made of stainless steel
Plug and play level limit switch without calibration
