Abstract
According to this method the linear expansion (.DELTA.L) of a reference shaft is measured with reference to that of the power shaft. The linear expansion of the reference shaft (R.sub.3) is converted into a movement of rotation of an annular phonic wheel (B.sub.3) by means of the free end (J) of this shaft engaged in a helical groove in the inner surface of the annular wheel (B.sub.3).
