- 中心部に被計測流体内で回転するロータが受けるトルクにより回転する軸を固定し、前記中心部から対称にそれぞれ扇形に延び、全体として平面視蝶形をなす平板状のボビンプレートと、
前記ボビンプレートの各扇形部分において、少なくともコイルの電流が中心軸から離れる方向の部分と近づく方向の部分を備えるように扇形に巻回し、外部から通電可能なコイルと、
前記各コイル毎に該コイルを上下から挟んで対向し、互いに磁極が異なると共に、各々前記対称に延びる平板状のボビンプレートの共通する中心線を挟んで平面上で極性を異ならせた、各コイル毎の一対の永久磁石と、
前記ボビンプレートの回転位置に対応した光または影の位置を検出する受光部材と、
前記受光部材の受光位置信号に応じて前記ボビンプレートの回転前の位置に戻すように前記コイルへの通電量を制御し、該通電量によりトルクを求める手段とを備えたことを特徴とする回転粘度計用トルク検出器。 - 前記小孔は前記コイル内において前記ボビンプレートを貫通する位置に形成したことを特徴とする請求項1記載の回転粘度計用トルク検出器。
- 前記コイルは前記平板状のボビンプレート内に埋設されていることを特徴とする請求項1記載の回転粘度計用トルク検出器。
