ABSTRACT:
A vibrating transducer is coupled to one end of an elongated vibrating plate and a receiving transducer is coupled to the other end of the vibrating plate. Langevin transducers are used for the vibrating and receiving transducers. Each transducer includes a pair of annular piezoelectric elements. The vibrating transducer is connected to an oscillator. A controller controls the oscillator. Detection signals of a voltage sensor, which detects the vibrating state of the receiving side of the vibrating plate, are fed back to the controller. The controller controls the oscillator such that the phase difference between the vibration of the vibrating side and the receiving side is within a predetermined range and that the receiving side is vibrated by amplitude greater than or equal to a predetermined amplitude.
