发明名称 MEASURING DEVICE OF THICKNESS FOR WEB HAVING STOP ROLLER AND CONTROLLING METHOD FOR THE SAME
摘要 PURPOSE: A device for measuring the thickness of a web with a stopping roll and a controlling method thereof are provided to measure the thickness of an object by using a LVDT(Linear Variable Differential Transformer), thereby preventing a radiation leakage or excessive exposure to the radiation. CONSTITUTION: A device for measuring the thickness of a web with a stopping roll comprises a measuring sensor(100) and a controlling unit(150). The measuring sensor consecutively measures a distance from a positioned position to a spot where an object of a stopping roll is touched when the object is not existed or a distance from the positioned position to a spot corresponding to the spot where the object of the stopping roll is touched when the object is not existed when the object is transferred while being touched to the stopping roll. The controlling unit measures the thickness of the transferring object by using a difference of the distance measured by the measuring sensor when the measurement object is not existed and the distance to the object measured by the measuring sensor.
