Electric micrometer detector method of manufacturing the same, and electric micrometer detector

摘要

PPROBLEM TO BE SOLVED: To provide an electric micrometer-use detector which is high-quality and inexpensive. PSOLUTION: The electric micrometer-use detector 10 which includes coil part assemblies 14a (14b), wherein positions of coils 34a (34b) are determined and fixed to axial positions and their perpendicular positions with respect to magnetic lids 30a (30b) such that the coils 34a (34b) are arranged on prescribed axial positions and their perpendicular positions with respect to the magnetic lids 30a (30b), is characterized in that the axial position and its perpendicular position of a magnetic case 12 are determined and fixed with respect to the magnetic lids 30a, 30b of the respective coil part assemblies 14a, 14b, such that in the magnetic case 12, the two coil part assemblies 14a, 14b are arranged symmetrically about the center position PSB0/SBof the magnetic case.
