The invention discloses a compensation adjustment method for a tensiometer roll. The method comprises steps as follows: a designed vertical distance value h between a roll top line and a rolling lineof the tensiometer roll is acquired; a drive side tension detection value F1 and a work side tension detection value F2 of the tensiometer roll during stable production of a rolling mill are acquired;a compensation value delta h is determined according to the designed vertical distance value h, the drive side tension detection value F1 and the work side tension detection value F2, and the equation solution is as follows: delta h=(F1-F2).h/F1; and the vertical position of the work side of the tensiometer roll is adjusted according to the compensation value delta h. According to the compensation adjustment method for the tensiometer roll, the position of the tensiometer roll can be quantitatively adjusted, detection deviation is eliminated or reduced, accurate measurement of tension deviation is guaranteed, the steps are simple, and accuracy and reliability are high.
