上記可動体を非磁性導電体より形成し、該非磁性
導電体より成る可動体を上記空隙を通る磁束の大
略なかばをさえぎるように上記空隙内に挿入し、
上記対をなす磁極の一方を通る磁束が上記可動体
の偏位に伴なつて減少又は増加する時上記磁極と
対をなす他方の磁極を通る磁束が上記可動体の偏
位により等量だけ増加又は減少するようになして
上記対をなす磁極の各々を通る磁束の総和が上記
可動体の偏位により変化しないようになし更に上
記対をなす磁極の磁束の差を交流電圧として検出
し得るように上記磁極に検出線輪を配設したこと
を特徴とする偏位検出装置。 at least a pair of fixed magnetic poles, a wire ring for generating alternating magnetic flux on the fixed magnetic poles, a gap through which the magnetic flux generated by the wire passes, and a wire inserted into the gap in a direction perpendicular to the magnetic flux. In a deflection detection device having a movable body whose deflection is to be detected, the movable body is arranged so as to be able to deflect without contacting the magnetic pole within the above-mentioned space,
The movable body is made of a non-magnetic conductor, and the movable body made of the non-magnetic conductor is inserted into the gap so as to block approximately half of the magnetic flux passing through the gap,
When the magnetic flux passing through one of the pair of magnetic poles decreases or increases as the movable body shifts, the magnetic flux passing through the other pair of magnetic poles increases by the same amount due to the deflection of the movable body. or so that the sum of the magnetic flux passing through each of the pair of magnetic poles does not change due to the displacement of the movable body, and furthermore, the difference between the magnetic fluxes of the pair of magnetic poles can be detected as an alternating current voltage. A deviation detection device characterized in that a detection wire ring is disposed on the magnetic pole.
