摘要： The invention relates to a layered sensor element (10) which is used, in a gas sensor, to detect a physical property of a measuring gas, preferably to determine the temperature of the measuring gas or the concentration of a constituent of the measuring gas. Said sensor element (10) contains a meandering heating element (41) which is embedded in a porous insulating element (43). At least one separating element (44) is provided between adjacent sections of the meandering heating element (41), said separating element having a lower proportion of pores than the porous element (43) insulating the heating element.

摘要： The invention relates to a heating device (40) for a sensor element (10) of a gas sensor, which is used particularly for analyzing the exhaust gas of internal combustion engines. Said heating device (40) comprises a heating element (43) which is provided with an electrically resistant layer and is electrically insulated from at least one solid electrolyte layer (23, 24) by means of a layer containing barium and/or strontium and/or calcium, wherefore the heating element (43) is embedded in a first insulating means (41) which is bordered by a second insulating means (42). The first insulating means (41) is provided with a higher proportion (in percent by weight) of barium and/or strontium and/or calcium than the second insulating means (42).

摘要： The invention relates to a sensor element (10) which is used to determine a property of a test gas, preferably the concentration of a gas component in the test gas. The sensor element (10) comprises at least one electrode (42, 43) which is placed on a solid electrolyte (21, 22) and which is connected to the measuring gas by means of a diffusion path wherein a diffusion barrier (51, 151) is arranged. A means (52, 152) is arranged in the area on the side of the diffusion barrier (51, 151) opposite the electrode (42, 43). Said means reduces the diffusion cross section in the region on the side of the diffusion barrier (51, 151) facing away from the electrode (42, 43).

摘要： The invention relates to a sensor element (10) which is especially used to determine the concentration of a gas constituent of a test gas, preferably the oxygen content of an exhaust gas of an internal combustion engine. Said sensor element comprises a first electrode (41) and a second electrode (42) that are electrically connected by means of a solid electrolyte (21). The second electrode (42) is arranged in a test gas chamber (31) which is integrated into the sensor element (10) and communicates with the test gas outside the sensor element (10) by means of a diffusion barrier (51). The volume of the measuring gas chamber (31) is smaller than the volume of the diffusion barrier (51).

摘要： The invention relates to a ceramic laminated composite having at least one solid-electrolyte layer (11), an electric resistance strip (20), which is embedded in an insulation while running in a, in particular, meandering manner, and two electric supply strips (24, 25) leading to the resistance strip (20). In order to reduce the risk of the formation of cracks in the insulation, the resistance strip (20) is made of a material having a specific ohmic resistance greater than that of the material of the supply strips (24, 25) and has, with a small strip thickness, a largest possible width.

摘要： The invention relates to a sensor element (10) serving, in particular, for detecting a gas component in a test gas, preferably for determining the oxygen concentration in an exhaust gas of an internal combustion engine. The sensor element (10) comprises a strip conductor (101), which is applied to a solid electrolyte (21, 22) and which has an electrode (101a) provided in a measuring area (11) of the sensor element (10), and an electrode supply (101b) leading to the electrode (101a) and being situated in a supply area (12) of the sensor element (10). A heating element (51) is provided for heating the measuring area (11) of the sensor element (10). The strip conductor (101) comprises a narrowing (60) in a transition area (13) between the measuring area (11) and the supply area (12). In addition, the electrode (101a) comprises a first electrode section (81) and a second electrode section (82). The first electrode section (81) is, in a transition area (13) between the measuring area (11) and the supply area (12), connected to the electrode supply (101b), and the first and second electrode sections (81, 82) are electrically connected to one another only on their sides situated opposite the supply area (12).
