本発明は、全般的には、管に機械的に取り付けられてこれを封止する流体継手に関し、より具体的には、流体継手に取り付けられるワイヤレスセンサおよびその使用方法に関する。
一般に、流体配管、例えばチューブまたは管のための継手の1つのタイプとして、流体配管に緩くはめ込まれるコネクタボディと、このコネクタボディを圧縮しかつ/または流体配管の外面に対して物理的に変形させ、これにより1つもしくは複数のシール部および強固な機械的結合部を形成するドライブリングと、が挙げられる。
本発明の例示的実施形態の簡単な概要を提示する。当該概要は、本発明の重要要素を区別するものまたは本発明の観点を限定するものではない。
例示的実施形態を図に示し、説明する。ここに示している各例は、本発明を限定するものでない。例えば、1つもしくは複数の特徴は、他の実施形態および他のタイプの装置においても利用可能である。さらに、特定の用語は簡便性のためにのみ用いており、限定と取られるべきものではない。さらに、各図中、同じ要素の指示には同じ参照番号を用いている。
