Vibrosonde: Vibrating Rod Type Level Sensor for Solids
A rod level sensor works on vibrating rod principle is used as level measuring instruments to monitor the level of powders and granular materials where vibrating fork level sensor break down due to material blockage. This vibrating rod for solid is suitable to avoid overflow conditions.

Operating Principle
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.
