    摘要: A gas sensor having a sensor element which is immobilized in gas-tight fashion in a metal housing. The gas sensor has a double-walled protective tube with an outer protective sleeve and an inner protective sleeve, each of which possesses openings for the entry and/or exit of gas. The inner protective sleeve forms a gas space into which the sensor element projects with a section at the measurement-gas end. The outer protective sleeve is a sleeve having a closed enveloping surface, the openings for the entry and/or exit of gas being arranged in the cavity at the end face of the sleeve. The gas space formed by the inner protective sleeve has, perpendicular to the extension direction of the sensor element, a rectangular cross section.

    摘要: A carrier system for a high-frequency antenna having at least two electrodes situated at a predefined distance from one another and implemented as essentially flat, a dielectric being situated between the at least two electrodes, is distinguished in that the at least two electrodes are situated on a frame part which is as difficult to deform as possible. The frame part preferably has recesses or openings in such a way that air having ∈r=1 is essentially situated between the at least two electrodes as the dielectric.
