Operating Principle

The working principle of tuning fork type level switch is based on tuning fork’s amplitude measurement. A specially shaped tuning fork is continuously vibrating at its natural frequency using piezo-electric elements and detecting the changes in amplitude 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 amplitude of oscillation of tuning fork level switch dampens. The change in amplitude is detected by the microprocessor leading to a switching decision.
