Abstract

본 발명은 측정된 값 결정을 위한 수동 표면파 센서에 관한 것으로, 여기서, 그 측정된 값은 원격 측정위치 질문소자(1)로부터 무선에 의해 전송되며, 그것은 질문펄스로서 센서소자(5, 15)로 무선에 의해 에너지를 전송한다. 본 발명에 따른 이 표면파 센서는 접촉하지 않고 측정된 값을 습득하는데 적당하고, 표면파 장치는 센서소자이고 표면파 기준소자는 위상 판별 및/또는 전파 시간 측정에 제공된다. 추가의 개선책으로서, 치프된 전송신호를 가지고 동작되며 치프된 반사기를 가지는 센서가 설명되며, 여기서는 그 장치내에 기준소자를 대신하여 기준기능이 있다. 치프된 기능을 가지도록 설계된 센서는 다른 물리적이거나 유사한 변수의 측정을 위해 긴급히 온도 보상된 센서(제12,13도)의 특징을 가진다.
