ABSTRACT:
A multi-channel ultrasonic inspection system includes an ultrasonic inspection unit which generates ultrasonic inspection pulses, supplies the pulses to a part being inspected, produces an output signal proportional to the level of echo pulses received within a predetermined gate time window following generation of the inspection pulses, and generates an alarm signal whenever the output signal exceeds a predetermined gate level. The system also includes data recording apparatus having a microcomputer, a mathematics processor chip, a control panel, and a printer. A gate reference level for each channel is stored by the microcomputer by pressing a channel button on the control panel, supplying inspection pulses to a workpiece having a standard defect, and adjusting the gain or gate level of the ultrasonic inspection unit until an alarm signal is generated. The operator then presses a START button which causes the reference levels to be printed. When an echo pulse is received which exceeds the gate reference level, an alarm signal is generated which causes a print-out of the difference between the defect echo pulse level and the gate reference level.
