Operating Principle
LSVR Vibrating rod is a single element tuned mechanical element-type level sensing device.
When the material touches the rod, vibration stops as resonance gets disturbed.
Electronics of LSVR excites the piezo-electric-crystals inside the tuning rod, which makes
the rod vibrate at it's natural resonance frequency in free air.
Amplitudes of vibration are above threshold when the rod is free to vibrate.
Amplitude of vibration, as sensed by the electronics falls below the threshold, material presence is
thus detected by observing the amplitude of vibration.
