Suitable for detecting limit levels in liquids with a maximum dynamic viscosity of 10,000 mPa ⋅ s and a minimum density of 0.7 kg/dm3. Specially useful in cases in which floating switches cannot be used due to currents, turbulence or adherence. Ideally suited as an overflow alarm or for dry-run protection. Due to the WHG approval, VibraFox® can be used as part of an approved overfill prevention system.

The vibration fork of VibraFox® is excited to its resonance frequency. When the fork comes into contact with the medium, there is a change in frequency which is detected by the electronics and converted into a switching signal. The unique evaluation electronics enable the application of the system even under adverse conditions, e.g. in vibrating tanks or with turbulent liquid surfaces.
