  • Abstract
    This paper describes the structure and output voltage characteristics of a rail displacement sensor comprising triangular coils. The calculation was demonstrated under a few assumptions. The maximum output voltage error between the measured and the calculated values was 2.4%. The influence of rail wear on output voltage leads to a displacement error of 12 mm.
