ABSTRACT:
A supersonic sensor head for a supersonic non-destructive test apparatus is disclosed. The supersonic sensor head includes a supersonic vibrator for transmitting and receiving supersonic waves, a holder having a base end and an opening end, and a soft gel material contact medium provided in the holder between the vibrator and a test object. The holder is coaxial with the vibrator so that the base end of the holder is in contact with a free end of the vibrator. By way of the contact medium, the supersonic vibrator indirectly contacts the test object. When a contact part of the contact medium is pressed against the test object, the vibrator comes into close contact with the contact medium, and the contact medium comes into close contact with the test object. The opening end of the holder restricts the deformation of the contact part of the contact medium.
