Claims (1)
- 外周部に多数の突起を刻んだ歯車状のパルサと、該パルサの外周部に対し近接配置されて磁界をつくり且つ該磁界を前記パルサの突起が通過した時の誘導起電力の電圧変化を捕えて前記パルサの回転を検出する回転センサとの組み合わせから成り、しかも、同じ回転軸上に複数組のパルサ及び回転センサを並べて配置した自動車用エンジンの回転検出装置において、各パルサの径寸法を異なるものとして、該各パルサの外周部に対し近接配置される回転センサを半径方向に段違いに配置すると共に、この段違いの配置により各回転センサの相互の磁界を半径方向にずらして重ならないようにした上で各組のパルサ及び回転センサを互いの距離を近づけて配置したことを特徴とする回転検出装置。
