PURPOSE:To obtain the amount of displacement of a distortion transfer unit with high precision with respect to external force, by making the maximum crystal grain diameter of the cross section perpendicular to the direction of long axis below 200mum when the distortion transfer unit is made of Fe-Ni. CONSTITUTION:A displacement converter is formed by joining distortion transfer unit 1 with semiconductor detector 2 having a fixed resistance region. In case distortion transfer unit 1 is made of alloy such as Fe-Ni or Ni (30%)-Co (16%), the non-linear error of its displacement depends on the maximum crystal grain diameter of the cross section perpendicular to the direction of long axis. By making the maximum crystal grain diameter below 200mum, it is possible to obtain the amount of displacement of the distortion transfer unit with high precision with respect to external force. |
