Vibration Level Switch: Foaming beads application
Verification test by foaming beads
Matsushima Vibrating Level Switch can detect the extremely light materials.
Foaming beads (diameter 1mm, bulk density 0.02g/cm3)

Principle:
Small vibrating inner probe resonates with the outer probe.
When the outer probe is covered by the materials, the resonance is attenuated, which makes a detection signal.
The precise design and process technology makes the reliable detection even for lightweight materials like bulk density 0.02g.cm3.
