Vibrating Rod Point Level Switch (LSVR)

Operating Principle :

• Electronics of LSV-R excites the piezo-electriccrystals inside tuning rod, which makes the rod vibrate at it's natural resonance frequency in free air.
• Amplitudes of vibration are above threshold when rod is free to vibrate.
• When material touches rod, vibration stops as resonance gets disturbed.
• Amplitudes of vibration, as seen by electronics falls below the thresholdstrength, material presence is thus detected.
