    • PURPOSE:To maintain the temperature of a detector of radiant rays constant and to improve the accuracy of measurement, by cooling a accomodating room of the detector by a cooling mechanism and approaching or separating the radiant ray detector to and from an accomodating body of the material to be inspected. CONSTITUTION:Radiant rays radiated from the material to be inspected in a piping 1 is transmitted through a wall of the piping 1 and is reached to a radiant rays detector 6 and is detected. The temperature of the detector 6 is detected by a temperature detector 9 and a detector driving mechanism is operated in accordance with said temperature. When the temperature is high, the detector 6 is separated from the piping 1 and when the temperature is low, the detector 6 is drawn near the piping 1. Accordingly, the temperature of the detector 6 is kept constant and errors due to temperature fluctuation are decreased.
    • 目的:为了保持辐射线检测器的温度不变,提高测量精度,通过冷却机构冷却检测器的住宿室,并将辐射线检测器接近或分离到材料容纳体内 被检查。 构成:从管道1中要被检查的材料辐射的辐射线通过管道1的壁传递并到达辐射线检测器6并被检测。 检测器6的温度由温度检测器9检测,并且检测器驱动机构根据所述温度进行操作。 当温度高时,检测器6与管道1分离,当温度低时,检测器6被吸入管道1附近。因此,检测器6的温度保持恒定,温度变动引起的误差为 减少。
