MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a measuring apparatus capable of consecutively and quantitatively measuring the degree of creep damage of piping.SOLUTION: A measuring apparatus comprises an electromagnetic ultrasonic sensor T1 which measures the wall thickness of piping P, a mobile body K to which the electromagnetic ultrasonic sensor T1 is attached so that the measurement surface of the electromagnetic ultrasonic sensor T1 faces the outer peripheral surface of the piping P, and which moves along the longitudinal direction of the piping P; and guide members T102-T105 which are interposed between the electromagnetic ultrasonic sensor T1 and the piping P to guide the mobile body K so that the distance between the electromagnetic ultrasonic sensor T1 and the piping P is held at a constant distance when the mobile body K moves along the longitudinal direction of the piping P.SELECTED DRAWING: Figure 5
