    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: Disclosed is a sensor arrangement comprising a sensor (10) measuring a gas parameter of a gas that is to be measured. Said sensor (10) is provided with a measuring element (13) which is disposed in a housing (12) and a protruding section (131) of which extends from said housing (12) at least on the side of the gas that is to be measured. The inventive sensor is also provided with a gas duct (11) through which the gas to be measured flows and which comprises a sensor inlet (25) and a seat (26) receiving the housing (12), said seat (26) encompassing the inlet (25) and being fixed to the gas duct (11). In order to be able to direct the measuring element (13) in a reproducible manner relative to the flow of gas during mounting of the sensor arrangement without the assistance of a mechanic, the seat (26) is provided with an internal thread (28), the beginning of which is oriented in relation to the flow of gas that is to be measured, while the housing (12) is provided with an external thread (34) which can be screwed into the internal thread (28) and the beginning of which is oriented in relation to the measuring element (13). The housing (12) is fastened to the seat (26) by means of a given tightening torque.

    摘要: The invention relates to a sensor element (10) having a laminate design, for detecting a physical property of a gas, particularly for detecting the concentration of a gas component in the exhaust gas of an internal combustion engine. The sensor element (10) has a measuring device (22), which serves to detect a physical property of the gas, and has a heating device (21). The heating device (21) contains a heater (30) that is electrically connected to a first heater supply conductor (31) and to a second heater supply conductor (32). The first heater supply conductor (31) is placed in a layer level situated between the second heater supply conductor (32) and the measuring device (22). An at least nearly constant electric potential is applied to the first heater supply conductor (31).
