Abstract
This application discloses an apparatus for detecting leaks or thin spots in condenser tubes by means of ultra-sonic radiations. A number of ultrasonic generators is placed within the chamber or enclosure of the tubes of a condenser, and the generators transmit ultrasonic waves to flood the chamber with energy. A detector sensitive to the frequency of the ultrasonic waves is scanned over the open ends of the condenser tubes. When the detector is at the end of a tube having a hole or thin spot, the intensity of vibrations picked up by the detector will be relatively high, and thus the defective tube is located. A condenser particularly adapted to testing of the tubes thereof by this method is also disclosed.
