Abstract

PURPOSE:Voltage generated by magnetic metal strips running in AC magnetic flux is detected, and by processing in a circuit with an amplifier which can change amplification, detection of breadthwise distribution state of lengthwies average stress by rolling distortion is done regardless of plate thickness or warps.
