DEVICE FOR MEASURING INTERVAL BETWEEN EDGE ROLLS USING ULTRASONIC WAVES

摘要

PURPOSE: A device for measuring interval between edge rolls using ultrasonic waves is provided to prevent damage of sensors due to high temperature, moisture and vibration, a stop of operation, frequent demands for maintenance and frequent measurements and to improve accuracy and actual utility. CONSTITUTION: A device for measuring interval between edge rolls using ultrasonic waves includes an edger roll supporting rod measuring unit (44) mounted at a fixed side (41) for measuring interval of edger roll housing (42), and an underwater ultrasonic wave sensor (45) mounted at the center of the edger roll housing (42) for measuring distance from the housing to an edger roll (40) and diameters of the edger roll. The edger roll supporting rod measuring unit has telescopic cylindrical pipes having different diameters and a variable resistor connected to a wire drum shaft for showing the change of length of a wire wound on a wire drum into the change of linear resistance.
