<p>PURPOSE:To reduce fluctuations with a simple structure. CONSTITUTION:This shape detecting device of a rolled material is provided with a shape detecting roller 1 rotated in contact with the belt-like rolled material traveled in the longitudinal direction, a plurality of load sensors 2 arranged along the shaft center direction of the roller 1, and a charge amplifier 3 converting the load measurement signal by the load sensor 2 into voltage. The load sensors 2 are arranged at the phase difference of 120 deg. in the peripheral direction, and three load sensors 2 having the phase difference of 120 deg. from each other are connected to the same channel of the charge amplifier 3.</p> |
