Abstract
Description
非特許文献1に開示された装置の欠点は以下のとおりである:
・検出器の構成が複雑であるので、装置の信頼性が比較的低く、寿命が比較的短い。
・固体電解質を用いた酸素検出器の水蒸気に対する耐熱性と耐腐食性とが比較的低い。
・測定室内の水蒸気の分圧を安定化させるのが難しいので、応答時間が比較的長く、感度に欠ける。
・温度及び配管を安定に保つのが難しいので、水素濃度の測定精度が比較的低い。
実際、本発明による検出器の設計は、水素検出器の寿命を延ばし、かつ作動媒体のパラメータの広い範囲においてその動作の信頼性を向上させるだけでなく、水素検出器の測定値の安定性及び信頼性を向上させることができる。
封止材3はガラスセラミックスであり、その組成は、酸化ケイ素(SiO2)50重量%、酸化アルミニウム(Al2O3)5重量%、酸化ホウ素(B2O3)20重量%、酸化チタン(TiO2)10重量%、酸化ナトリウム(Na2O)12重量%、酸化カリウム(K2O)1重量%、及び酸化マグネシウム(MgO)2重量%である。封止材は、空気中から検出器内の空洞への酸素の侵入を防ぎ、基準電極の性質変化を避けるのに必要である。
