Operating Principle

The working principle of vibrating fork level switch is based on vibrating tuning fork’s natural frequency and amplitude measurement. A specially shaped tuning fork is continuously vibrating at its natural frequency using piezo-electric elements and changes in amplitude in the presence of application media are measured. The pressure applied on diaphragm drives the vibrating 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 amplitude of oscillation of vibrating fork level switch dampens or decreases as it covered with the solid application media. The change in amplitude is detected by the microprocessor leading to a switching decision. When the amplitude goes below a set threshold, vibrating fork type level switch trigger changes in output.
