Vibrating Fork Point Level Switch for Solids

Published on : Tuesday 30-11--0001

Working Principle

• Electronics of LSV excites the piezo-electric-crystals inside the tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air.
• Amplitudes of vibration are above threshold when tines are free to vibrate.
• When material touches the fork tines, vibration stops as resonance gets disturbed.
• Amplitudes of vibration, as sensed by electronics falls below the threshold strength, material presence is thus detected.

Features

• Compact size.
• Universal industrial power supply. 15 to 80 VDC & 15 to 260 VAC).
• Low power consumption.
• No calibration required.
• Various customized process connections. Starting from 1" threaded size.
• Settable switching delay as a standard feature.
• Remote electronics version available on request.
• Exd version available-suitable for Gas Group IIC, T6 as per IEC 60079-1-2007 & IEC 600529-2001

Applications

• Free flowing powders and granules (size max. 10mm).
• Suitable for side as well as top mounting.
• PTFE/PFA/ECTFE coatings for corrosive solids
• Minimum and maximum fail safe field selectable.
• Process temperature max 250 ºC.
• Process pressure max. 15 bar.
