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 (,) and an oscillator/receiver (,), each provided with electrodes (,). The oscillator/transmitter (,) and the oscillator/receiver (,) are made of the same material. The oscillator/transmitter (,) and the oscillator/receiver (,) are arranged directly one behind the other, in the sound propagation direction, in particular flat-bonded one on the other.

Monitor head for ultrasound control by pulse echo process

This invention relates to an ultrasonic angle test probe comprising at least two ultrasonic transducers for respectively generating and receiving ultrasonic waves propagating in different directions. According to the invention, in order to obtain relatively small wedge shaped coupling members and small coupling surfaces on the side of the probe contacting the workpiece, a plurality of transducers are disposed above one another instead of side by side. In a typical embodiment, a first transducer is disposed on a first wedge-shaped coupling member and second transducer is disposed on a second wedge-shaped coupling member superposed upon said first coupling member for providing different angles of propagation of sound waves responsive to energizing one or the other transducer.
