PURPOSE:To make it possible to accurately obtain a measured value, by providing a detector for detecting radiation intensity between frame pieces through a high frequency attenuation type buffer apparatus. CONSTITUTION:A detector 12 is held by a buffer apparatus 13. The buffer apparatus 13 consists of vibration proof rubber 13a, a damper 13b and a spring 13c and vibration of several 100Hz is absorbed by the vibration proof rubber 13a and the vibration of a rolling machine is suppressed within a short time by the damper 13b and the spring 13c has function extremely reducing the transmission of vibration impact. Because the buffer apparatus 13 fixes the detector 12 at three points or more, said apparatus 13 can prevent not only the absorption of vibration impact in vertical and horizontal directions generated in the rolling machine but also the rotary motion of a radiation transmission type thickness meter. Therefore, even if the radiation transmission type thickness meter is arranged to the rolling machine, the accurate measurement of the thickness of a plate can be performed without receiving the effect due to vibration and impact. |
