１．Outline
Vibrating level switch can detect a storage level of particulate materials from very lightweight powders to
grains.
Vibrating probe will oscillate in a fixed frequency (resonant frequency) by piezo element, if coating with
powders of storage materials, vibrating amplitude will be significantly decreased. This decreased amplitude
will be detected by the part of electronic circuit, and a contact signal is output as a level signal.
