APPARATUS AND METHOD FOR MEASURING THE THICKNESS OF SOLID MATERIAL AND THE ULTRASONIC VELOCITY

摘要

PURPOSE: A device and a method for simultaneously measuring thickness and ultrasonic wave speed of solid material are provided to measure ultrasonic wave speed, thickness of material and elastic coefficient of a thing measured by applying ultrasonic wave to the thing measured without manufacturing a contrast test sample. CONSTITUTION: A device for simultaneously measuring thickness and ultrasonic wave speed of solid material includes an ultrasonic wave generator generating ultrasonic wave and transferring it to a thing measured(1), an ultrasonic wave receiving part for receiving ultrasonic wave reflected from the thing to be measured, a calculating part determining added clock number by starting count at a standard time when ultrasonic wave is generated and stopping count at the time when ultrasonic wave is received, an operation control unit(9) determining ultrasonic wave progressing time, calculating a distance between an ultrasonic wave transferring point and ultrasonic wave receiving points, and an output unit(10) for outputting calculated information of the operation control unit to the outside.
