    摘要: Proposed is a seal (28) for the sensor element (16) of a gas sensor (10), in particular a sensor for the determination of the oxygen content of exhaust gases from internal-combustion engines. The seal (28) surrounds the sensor element (16) in a longitudinal bore (14) in the sensor housing (11) and has two seal elements (29, 30) between which is located a resilient supplementary seal (31) which has a lower porosity than the other two seal elements (29, 30).

    摘要: The disclosure relates to a measurement sensor (10) intended in particular for determining the oxygen content in exhaust gases from internal combustion engines. The sensor comprises a sensor element (14) mounted in a metal housing (13, 30) and attached to connecting cables (18) leading out of the housing (13, 30). The cables are enclosed in a cable sheath (12) and a reference atmosphere for the sensor element (14) can be introduced into the housing (13, 30). The cable sheath (12) is provided at least in areas of its outer surface with at least one gas-permeable section through which the reference atmosphere can penetrate into the interior of the cable sheath (12) and from there into the housing (13, 30). A porous PTFE tube is especially suitable as the cable sheath.

    摘要: An electrochemical measurement probe for determining the oxygen content of gasses, in particular exhaust fumes of internal combustion engines, has a voltage-free sensor (14) mounted in a housing (12). The sensor (14) has an oxygen ion-conducting solid electrolyte body (23) shaped as a tube closed at one side that contains a measurement electrode (25) with a printed circuit (27) located at the connection side. The measurement electrode (25) is covered with an electrically insulating, porous protective layer (29). An electrically insulating layer (21) is laid on the printed circuit (27) at the connection side. The protective layer (29) overlaps the end of the insulating layer (21) at the side of the electrode, so that the underlying functional layers (25, 27) and the solid electrolyte body (23) are electrically insulated against the electroconducting substances entrained in the measurement gas.

    摘要: The invention proposes a probe (1) for determining the oxygen content of exhaust fumes from internal combustion engines in particular, comprising a sensor element (20) which is disposed in a metallic housing (2) and which is in contact with connecting cables (4, 5) that lead out of the housing (2). These connecting cables (4, 5) are surrounded by an insulating sleeve (12, 13) made of PTFE. At least one part of the lateral surface of the insulating sleeve (12, 13) has a gas-permeable section (17) so that the reference atmosphere can pass through into the interior of the insulating sleeve (12, 13) and from there into the housing (2) but which also prevents penetration of liquids such as fuel, condensation water, etc. This is achieved, for example, by an additional porous PTFE-film (18) which is applied to the gas-permeable section (17).

    摘要: The invention relates to a gas sensor, especially a lambda probe, for detecting the pollutant or oxygen content of the exhaust gases of internal combustion engines, comprising a housing which accommodates at least one sensor element, said sensor element having a connection-side section and a measured gas-side section, and a connecting element. Said connecting element connects the sensor element to several electroconductive supply leads via its connection-side section, said sensor element having several electroconductive contact surfaces. The inventive gas sensor is characterised by a connecting element (29) which is made up of a spring element (41) produced in a single piece from a ceramic material.

    摘要: The invention relates to a method for producing a sensor element, specially for determining the oxygen content in exhaust gases from internal combustion engines, wherein a composite material comprising at least one ceramic paste available in the form of a film (green film) is sintered to the sensor element and the sharp edges of the sensor element are broken to improve thermal-shock resistance of said sensor element. The edges (36) of the sensor element (10) are broken before sintering occurs.
