BLOCK OF ACOUSTIC HEADS FOR NON-DESTRUCTIVE CONTROL

摘要

Block of acoustic heads for non-destructive (ultrasonic) control has at least one acoustic head with body with conical surface and spherical collet with pressing element for fixation of piezoelectric transformer and cavity for supply of contact liquid. On the body two rollers on parallel axles normal to axis of the head are fixed. The rollers surround with tension slat-copier that is made for instance as equidistant with respect to controlled surface.
