The Vibrating Fork Level Switch for solids is designed to reliably detect the presence or absence of solid materials in various industrial applications. It features a fork-shaped sensor that vibrates at a specific frequency; when immersed in solid material, the frequency changes, triggering an electronic signal.
Built to withstand harsh environments, this switch offers durability and is suitable for industries like food, pharmaceuticals, and chemicals. With easy installation and low maintenance, it provides fail-safe operation to prevent overflow. Its versatility makes it essential for maintaining optimal levels in silos and hoppers, enhancing overall operational efficiency.

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.
