Description
ここで、圧力センサ1、なかでも圧力検知部3は通常、直接外気に触れる部分のみならず、その他の部分も化学膜コーティング等によって防湿性を付与されており、また、半導体レベルで、所要の耐熱性を付与されている。
ここにおけるこの水分感知シート8は、たとえば圧力不透過性のものとすることができ、この場合は、圧力導入口6から取り込まれたタイヤ内圧は、水分感知シート8を迂回して圧力検知部3へ供給されることになる。
2 ハウジング
3 圧力検知部
4 電子部品実装基板
5 封止剤
6 圧力導入口
7 内圧検知スペース
8 水感知シート
Claims (2)
- タイヤ内圧監視システムに適用され、ハウジングによってホイールリムに取り付けられてタイヤ内圧を検知する圧力センサであって、
ハウジングに形成した圧力導入口と対応する位置でハウジング内に水分感知シートを配設し、前記ハウジング内に設けた圧力検知部との間で前記水分感知シートを挟み込み固定する螺合キャップの外面に、圧力の迂曲通路形成用の突条を設けてなる圧力センサ。 - 水分感知シートを、水溶性着色剤による印刷シートとしてなる請求項1に記載の圧力センサ。
