THE ULTRASONEL FLAW DETECTOR

The Ultrasonel instrument of Trevor-Johnstone Company for detection of flaws in locomotive frames and thin plates by measuring the intensity of ultrasonic waves is described. The Ultrasonel will detect either internal or surface defects. The internal defects may be revealed by either transparency or echo methods as may be convenient, whereas the surface flaws are detected by inclining the feelers at an angle to the surface. The feelers are set at an angle to the surface so that the ultrasonic waves move along the surface without penetrating the test material.
