probe for ultrasonic testing using the pulse echo method

摘要

The invention concerns a monitor head for ultrasound control by pulse echo process, in particular for producing a brief ultrasound pulse, unipolar as far as possible, comprising an oscillator/transmitter (26) and an oscillator/receiver (32), each provided with electrodes (28, 30, 34, 36). The oscillator/transmitter (26) and the oscillator/receiver (32) are made of the same material. The oscillator/transmitter (26) and the oscillator/receiver (32) are arranged directly one behind the other, in the sound propagation direction, in particular flat-bonded one on the other.
