Delivery Scope
Trumen Vibrating Fork Point Level Switch - LSV
Model No: LSV
Part No:
Trumen LSV is a vibrating fork level switch used in free-flowing powders and granules size upto max. 10 mm. This vibrating fork is ideally for solids and low bulk density materials. It detects the point level switch measurement reliably. LSV level switch is used as protection device of Hi and Low level switching in solid applications.
Features :
- Compact in Size and Fast Switching Response
- Suitable for Low Bulk Density Material
- No Calibratio required
- Tropicalized and potted electronics module
- Ingress protection : IP 68/66 (as per IS-13947), Ex-proof (Ex d T6 IP-66 IIC )
- Low power consumption (0.5 to 0.7 VA)
- Vibration complied as per IEC 60068 part 2-6

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.
