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： Multiple contacts are provided in an electrical contacting arrangement of a sensor element, and the sensor element has a connection-side section with contact points, or contact pads, which are each integrally bonded to a corresponding contact. Each of the multiple contacts, at least on the section in contact with the contact point on the sensor element, has a layer by which the integral bond is formed between the contact and the contact point on the sensor element. The contacts are joined to the corresponding contact points on the sensor element by diffusion soldering or diffusion welding. Each contact has a curved intermediate section which compensates for thermal and/or mechanical expansion and movements.
