    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: The invention relates to a measuring instrument, particularly an electrochemical measuring sensor, having a sensor element arranged at a measuring point, which sensor element can be connected via electrical connecting leads with an evaluating circuit removed from the measuring point, with the electrical connecting leads being guided so as to be protected against external influences, especially against high temperature influences, at least in the proximity of the measuring point. At its end facing away from the sensor element (12), a protective device (24) receiving the electrical connecting leads (22) is provided with a connecting device (30) which can be connected to a connecting lead (54, 56) to the evaluating circuit.

    摘要: A sensor arrangement for ascertaining physical properties of a liquid is proposed, having electro-acoustical converters (6) on a substrate (5) which are wettable with the liquid and are suitable for generating and detecting acoustical surface waves with predetermined wave modes. A Y-rotated quartz slice is used as the substrate (5), and above the substrate (5) is a waveguide layer (16); the standard of the Y rotation of the quartz slice and the material of the waveguide layer (16) are selected such that an extensive temperature compensation within the range of temperature of the liquid to be investigated is obtained.
