Abstract
A measuring sensor comprises at least one SAW (surface acoustic wave) element () serving as a sensor and identification unit, which is installed in a contactless manner inside a housing part () forming, in essence, a coaxial conductor. The housing part () is connected to the shield () of the connection cable whose signal conductor () extends in a contactless manner over a superficial coupling structure of the SAW element () without contact. In order to improve the near-field coupling, the coupling structure of the SAW element () comprises additively coupling partial structures, which are arranged on both sides of the signal conductor () and which, preferably with at least one strip conductor, encircle, at least for the most part, the SAW element () in the peripheral area, and which serve as an integrated discharge loop for pyroelectric charges.
