Vibration Type Level Sensor

VLS Series (Solid Level Measurement)

Vibration Type Level Switch: The VLS Series is designed for solid level measurement. The blade of the probe vibrates at its resonance frequency. When filling material covers the blade of the probe, the vibration stops. This is sensed by the electronic circuitry and the output relay switches. When the blade gets uncovered, the vibration will restart, and the relay will switch back.

The VLS series is a piezoelectrically driven vibration type level switch that detects the level in bins, silos, and hoppers filled with grained or powdered materials (bulk solids). The instrument can be used for overfilling protection or for high or low-level alarm.
