Title:
超音波検査システム
Document Type and Number:
Japanese Patent JP7010770
Kind Code:
B2
Abstract:
An ultrasonic inspection system includes an ultrasonic sensor which includes a piezoelectric element to transmit and receive an ultrasonic wave and a calibration piece, and a control device. The calibration piece includes a propagation portion extending along an upper surface of the piezoelectric element, and a propagation redirecting portion which is formed on one side in an extending direction of the propagation portion, and is connected to the piezoelectric element through a heat resistant adhesive. The propagation redirecting portion includes a slope inclined in a vertical direction to the upper surface of the piezoelectric element. The propagation redirecting portion is configured to reflect the ultrasonic wave incident on the propagation redirecting portion from the piezoelectric element on the slope and emit the ultrasonic wave toward the propagation portion, and reflect the ultrasonic wave which is reflected on an end surface on the other side in the extending direction of the propagation portion and incident on the propagation redirecting portion from the propagation portion on the slope and emit the ultrasonic wave toward the piezoelectric element.
