移動自在に収容されており、磁界発生部材の引き
付け力に抗して移動する上記磁性体の変位量を検
出部材により電気的な変化量として検出するセン
サにおいて、上記密封空間内がほぼ真空にされて
いることを特徴とするセンサ。 A magnetic body is movably housed in a sealed space provided in the casing, and a detection member detects the amount of displacement of the magnetic body as it moves against the attractive force of the magnetic field generating member as an electrical change amount. A sensor characterized in that the sealed space is substantially evacuated.
