The rugged, reliable, and highly accurate vibrating level switches in the LBV300 product family signal full, empty, or demand states in bulk materials. The tuning fork reacts to changes in density, and thus operates independently of silo shape or the tank material used. The rugged stainless steel tuning fork is piezo-electrically energized and vibrates at its resonance frequency when it is covered by bulk materials. This change is detected and converted into a switching signal. While the LBV310 compact device is used for horizontal mounting and to signal full states, the LBV320 cable-extended switch and the LBV330 tube-extended switch are used for vertical mounting in silos and bridge sensing ranges of up to 80 m and 6 m respectively. With a wide variety of thread and flange connections, and several electronic variants, the LBV330 offers a solution for almost all applications, even in potentially explosive atmospheres.
