LBV300 Level Sensors

The measurement principle of the tuning fork reacts to changes in density, therefore they operate independently of silo shape, tank material and they are also wear-free and maintenance-free. The sturdy stainless steel tuning fork is piezoelectrically energized and vibrates at its resonance frequency. If the tuning fork is covered with bulk material, the resonance frequency changes. This change is reliably detected by the integrated electronics and converted into a switching signal.

While the LBV310 sensor is principally used to signal full states or mounted laterally for demand or empty states, the LBV320 with suspension cable and the tube-extended LBV330 are used for vertical mounting in silos.
