Description
図1はこの発明の実施の形態の高濃度水素ガスセンサーを示すもので、絶縁性基板10上に、膜状の固体電解質12を形成し、その上に検出電極14及び基準電極16を互いに離間して設けている。検出電極14及び基準電極16は、配線を介して起電力計18に接続されている。さらに、これらを覆うヒータ20とその電源22、検出電極14の温度を測定する温度センサー24、及びこの温度センサー24の出力に基づいてヒータ20への給電を制御する制御装置26が設けられている。このヒータ20は、例えばメッシュ状に構成され、水素ガスに対する通気性と保温性とを兼ね備えている。ここで、検出電極14及び基準電極16を絶縁性基板10に配置し、その後、膜状の固体電解質12を形成するようにしてもよい。
