The working principle of the rod type level switch is based on continuously vibrating a mechanical rod at its natural frequency. The working principle of the rod type level switch is the same as the vibrating fork level switch. The only difference is that a vibrating rod kept vibrating instead of tuning fork. A vibrating rod is kept in mechanical vibrations at its resonance frequency by piezo-electric crystals. When the service material covers the rod probe, vibrations are damped which is sense electronically and processed signal is used for switching.
