Claims (1)
イバーケーブルにそれぞれ接続された光フアイバーコイ
ルと、固定面の側に変印自在に設けられ該固定面との間
で前記光フアイバーコイルを挾持する圧力伝達板と、圧
力変化により前記圧力伝達板を変位し前記光フアイバー
コイルを変形して該光フアイバーコイルの光の伝送損失
を可変する受圧部とを備えた圧力センサ。an optical fiber coil whose both ends are connected to a light-emitting fiber optic cable and a light-receiving fiber optic cable, respectively; and a pressure transmission plate that is movably provided on a fixed surface side and clamps the optical fiber coil between the fixed surface and the fixed surface. and a pressure receiving section that displaces the pressure transmitting plate and deforms the optical fiber coil in response to a pressure change to vary light transmission loss of the optical fiber coil.
