Description
図1は、従来技術による前記型式の測定システムの原理図を示しており、図2は、対応する本発明による装置を示す。
図2の本発明の測定システムは、図1に対して付加しているものが図示されている。間に置かれる共通のカップリングユニット5を経由する解析ユニット2及び試問ユニット3は、接続ケーブル61と接続可能である。このカップリングユニット5は、少なくとも、カップリング容量6及びカップリングインダクタンス7を持ち、これらは、前記接続ケーブル61の階段信号と平行に接続され、これにより、前記試問ユニット3は、高周波のカップリング容量6を用いて前記接続ケーブル61の階段信号にカップリングされる。それは、簡単な方法によって、圧力センサ4と負荷増幅器1の入力との間の測鎖(測定シーケンス)に高抵抗を維持させるだけでなく、有効信号及び識別信号からの必要な分離を生じる。
