Compact Vibrating Fork Liquid Level Switch

We are offering compact vibrating fork liquid level switch. Working principle electronics of lfv12 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.
