Abstract
The ultrasonic tubular transducer is activated at the centre thereof by two symmetrical electromechanical converters. The vibration generated by the two electromechanical converters is converted and then transmitted to the tube via a coupler. The ultrasonic transducer can be vibrationally isolated from the interfaces thereof by caps equally suitable for connecting the transducer to a stationary frame, a free end or another similar ultrasonic transducer. A device for pre-stressing electromechanical converters has a hole bored at the centre thereof in order to allow cables from the transducer as well as from adjacent transducers to pass therethrough.
Claims11
Tubular ultrasonic transducer to propagate acoustic waves in a fluid medium, and comprising:
- an electromechanical conversion device with active elements associated with at least one metallic tube for transmitting vibrations to the fluid medium,
- power supply cables of the conversion device,
- and a pre-stressing device of the active elements of said conversion device, wherein the conversion device is composed of two electromechanical converters arranged axially inside the tube, on each side of a coupler, which is located in the central part of the tube and in contact with the latter, and each end of the tube is equipped with a cap, the assembly forming a submersible symmetrical module with radial vibration.
