Enclosure Protection ClassIP-65/67 as per IS-13947
Process Pressureabsolute / max. 15 bar
Vibration TestAs per IEC 60068 part 2-6 sinusoidal, 10-55Hz, 0.15mm
Operating Principle :
Electronics of LFV excites the piezo-electric-crystals inside tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air.
When fork tines are immersed in liquid, the frequency of fork vibration falls due to the density of liquid.
This change in frequency is detected by electronic circuit.
Liquid presence is thus detected.
