    Operating Principle

    The working principle of tuning fork type level switch is based on tuning fork’s natural frequency measurement. A specially shaped tuning fork is continuously vibrating at its natural frequency using piezo-electric elements and detecting the changes in frequency in the presence of application media. The pressure applied on diaphragm drives the tuning fork's tines apart from each other and return to their original position when the pressure is removed. As the material level increases and comes in contact with the vibrating fork tines, the frequency of oscillation of tuning fork level switch dampens or decreases as it covered with the liquid application media. The change in frequency is detected by the microprocessor leading to a switching decision. The threshold frequency is set to match the natural frequency of tuning fork type level switch under water.
