Device for nondestructive ultrasonic inspection of accessible through an annular passage of small width cylindrical wall.

摘要

The device consists of a sheet (1), whose end supports a control probe (2) PROBE (2) in turn is composed of a first ultrasound transducer (24) acting as a transmitter and a second ultrasonic transducer (24) acting as receiver mounted pivotably at the end of the sheet (1) around two parallel axes in the longitudinal OF THE CARD ADDRESS (1) IN SITUATIONS spaced apart in the widthwise direction of the sheet) DE so that they rest IN A NARROW PASSAGE VOID IN CONTACT WITH THE WALL PARALLEL TO BE CHECKING IN TWO POSITIONS IN EACH SEPARATE THE MEANING circumferential annular passage.
