Tuning Fork Level Switch Principle | InstrumentationTools
Jan 9, 2015 · Tuning Fork Level Switch uses a metal tuning fork structure to detect the presence of a liquid or solid (powder or granules) in a vessel: An electronic circuit continuously excites the tuning fork, causing it to mechanically vibrate. When the prongs of the fork contact anything with substantial mass, the resonant frequency of the fork decreases.
When the level switch is used as a high-level point alarm, the liquid rises in the vessel (tank) or pipe making contact with the fork and causing the output state to switch i.e. dry-to-wet. Key features and benefits

Tuning Fork | Level Switches | Dwyer Instruments
Tuning Fork level switches are sensors with an electrical contact output at a specific level. Cost effective models are an ideal choice for level control of powders and fine grained solids. Models are easy to use and applications include mining, chemical processing, and food & beverage.
How a Vibrating Fork Level Switch Works
Vibration fork switches are only suitable for point level measurement. They consist of an oscillating or tuning fork, which resonate in air with a known natural frequency. The resonance frequency will be reduced when the fork is brought into contact with a medium.

In-Depth Analysis of the Working Principle of Tuning Fork Level Switches
The tuning fork level switch contains precise sensors that detect changes in the vibration frequency of the forks. As soon as the forks come into contact with the liquid, these sensors capture the changes and convert them into electrical signals.
