Vibrating Rod Point Level Switch for Solids

Working Principle

trumenVibrating rod is a single element tunned mechanical element-type level sensing device.

Electronics of LSV-R excites the piezo-electric-crystals inside the tuning rod, which makes the rod vibrate at it’s natural resonance frequency in free air.

trumen When Material touches the rod, vibration stops as resonance gets disturbed.

trumen Amplitudes of vibration are above threshold when rod is free to vibrate.

trumen Amplitudes of vibration, as sensed by the electronics falls below the threshold, Materials presence is thus detected by observing the amplitude of vibration.
