Abstract

The invention relates to an ultrasound control device for non-destructively inspecting a workpiece. The inventive ultrasound control device comprises a transmitting-receiving sensor provided with an element for connecting to the input surface of a controlled workpiece, a transmitter which is connected to the sensor and sends pulses produced thereby to said sensor, a receiver connected to the sensor and a screen which is connected to the receiver for displaying electric echo signals received by the receiver. The sensor transmits ultrasound pulses which, on one hand are reflected by the input surface and return to said sensor, and penetrate into the workpiece and are reflected at least once by the back wall thereof, on the other hand. Said ultrasound control device also comprises a bar display for visualising the received electric echo signals. At least one signal value displayed on said display in a real time results from one of electric echo signals reflected by the input surface: an input echo reflected by the input surface, at least one echo from the back wall and/or one signal calculated on the basis of several echoes reflected thereby.
