動計測装置。[Claims for Utility Model Registration] (1) A sleeve-type detection roller is rotatably attached to the fixed roller shaft via a bearing, and the detection roller is rotated along the material to be inspected.
In an apparatus for measuring the length, thickness, speed, etc. of a material to be tested, a space is formed between the fixed roller shaft and the inner peripheral surface of the detection roller, a medium is sealed in the space, and a medium is sealed in the space. An ultrasonic probe is attached to the fixed roller shaft in a space sealed with the medium at right angles to the shaft center.
The ultrasonic probe generates an ultrasonic wave, and the reflected ultrasonic wave passes through the medium and is reflected on the inner circumferential surface of the detection roller, and the reflected acoustic wave further passes through the detection roller and is reflected on the outer circumferential surface of the detection roller. The ultrasonic probe receives the reflected waves of the ultrasonic waves, and the ultrasonic probe transmits both of the reflected waves to an ultrasonic receiving/computing device. 1. An automatic detection roller wear amount measuring device characterized in that the detection roller wear amount is measured by measuring the thickness of the detection roller based on the difference in reception time. (2) In the apparatus described in claim (1) for utility model registration, the ultrasonic receiving and calculating device can determine the length, thickness, speed, etc. of the measured material based on the amount of wear of the detection roller measured as described above. An automatic detection roller wear amount measuring device characterized by having a configuration that allows coefficient correction of measured values.
