Page 3: Operating Principle
Amplitudes of vibration are above threshold when the rod is free to vibrate. When the material touches the rod, vibration stops as resonance gets disturbed. Amplitude of vibration, as sensed by the electronics falls below the threshold, material presence is thus detected by observing the amplitude of vibration. lsvr-manual-page01 www.trumen.in... -
