- the housing receiving the sensor element is designed as a tubular metal housing with a longitudinal bore.
- the metal housing On the outer circumference, the metal housing has a one-piece, circumferential flange, which is used to clamp the metal housing on a sealing seat formed on the gas line.
- the sensor element is inserted with a central section centrally in the metal housing and is by means of a
- Sealing arrangement which presses on the one hand against the sensor element and on the other hand against the bore wall of the longitudinal bore, and protrudes with a measuring gas end section and a connection end section on both housing sides from the housing.
- a connector plug is attached to the connection-side end section, which connects the sensor element with connection cables.
- the connection-side end section with connector is covered by a protective sleeve that opens the metal housing is pushed on and welded to it.
- the end section of the sensor element on the measuring gas side is enclosed by a protective tube with gas passage openings, which carries at its end on the housing side an outwardly facing annular flange which is fastened on the inside in the metal housing.
- the sensor element is accommodated in a tubular, metallic housing on which a sealing flange is formed by first compressing the tubular element, whereby a rounded one Bead forms, and then the bead is processed by kneading in such a way that two mutually inclined, axially circumferential sealing surfaces are formed.
- the sensor element is fixed in the housing and sealed in a gas-tight manner by means of a sealing arrangement, consisting of a molded gas-side ceramic molded part, a connection-side ceramic molded part and a sealing element arranged in between, so that it protrudes from the housing with the measurement gas-side end section.
- the ceramic molded parts consist of aluminum oxide (A1 2 0 3 ) and have central bushings for the sensor element.
- the steatite sealing element which also has a bushing for the sensor element, is inserted in a pre-pressed state between the ceramic molded parts. Then, on the measuring gas side, a stamp is applied to the ceramic gas part on the measuring gas side with a contact pressure, which crushes the pre-pressed sealing element and presses it against the housing wall and sensor element. An indentation is then introduced into the housing in order to
- connection-side molded ceramic part is supported on a radial shoulder present in the housing.
- a double protective tube with gas through openings is placed over the end section on the sample gas side, pushed into the end of the housing and welded to it.
- the sealing flange of the housing rests on a sealing seat formed in a connection piece of the exhaust pipe and is clamped by a union nut with an annular surface, which is screwed onto an external thread of the connection piece.
- the connection piece surrounds gas-tight an insertion hole for the double protective tube arranged in the sample gas line or in the exhaust pipe.
- the sensor according to the invention with the features of claim 1 has the advantage that the casing of the
- Sensor element which is also used to mount the sensor on the sample gas line, is composed of components that can be manufactured using fairly simple and inexpensive manufacturing processes and can be assembled in just a few assembly steps.
- the protective sleeve and / or protective tube are produced as a deep-drawn part, the deep-drawn or trimming edge present after the deep-drawing, which is usually removed after the deep-drawing, being used as a clamping flange for clamping the sensor in the sealing seat of the sample gas line.
- Stainless, heat-resistant steels or nickel alloys are used as the material for the deep-drawn parts. After deep drawing, the part of the trimming edge that is in the outside of the deep drawing die is held down Area lies, punched out or cut off, so that the flange has a defined radial dimension.
- the two deep-drawn parts are assembled and welded to the housing made as a simple tube.
- only the protective sleeve or only the protective tube can be provided with a flange. Providing only one sealing flange on one of the two components opens up the possibility of using a different manufacturing process for the other component than deep drawing.
- the flange on the protective tube forms the clamping flange for the sealing seat of the
- the banjo bolt has an annular stop face on one end face, which is able to bear against the protective sleeve on the underside of the flange facing the housing, and an annular clamping face on the other end face, which can be placed on the flange on the protective tube.
- the housing is formed by an inner protective tube which surrounds the measuring gas end of the sensor element and which in turn is concentrically surrounded by the protective tube.
- the inner protective tube has a one-piece flange on one of the tube ends facing the protective sleeve, which is joined to the two flanges on the protective tube and on the protective sleeve and is clamped onto the sealing seat.
- the total of three components namely inner protective tube, protective tube and protective sleeve, are added to the sleeve of the sensor element, and are held in the flange area by tightening on the sealing seat. Additional welds to produce, for example, a laser-welded lap seam or axial I-seam or fillet weld between
- Housing and protective sleeve on the one hand and housing and protective tube on the other are eliminated. This reduces both the investment and the manufacturing time for the manufacture of the sensor. At the same time, there is greater flexibility in the measurement gas-related lead dimension of the

- the flanged edge 121 serves to support a seal (not shown in FIG. 1) which encloses the sensor element 14 in a gas-tight manner and presses against the inner wall of the housing 12.
- the protective tube 13 is produced as a deep-drawn part which, at its end pushed over the lower end of the housing 12, carries an annular flange 131 which is integral with it.
- This flange 131 is from the so-called trimming edge existing after deep drawing formed, which is usually cut off in deep-drawn components.
- the modulation edge remains on the protective tube 13.
- the starting material for the production of the protective tube 13 is, for example, a 0.3-0.6 mm thick sheet of stainless, heat-resistant steel or a nickel alloy, the after deep-drawing held down area of the circumference outside the die . is punched out or cut, the cut running, for example, at a distance of approximately 1.5 mm from the outer contour of the protective tube 13.
- the protective tube 13 and the protective sleeve 11 are pushed onto end regions of the housing 12 which face away from one another and are firmly connected to them, for example by laser beam welding.
- the exhaust gas tube 10 has an insertion opening 19 in its tube wall 101, which is concentrically surrounded by a connecting piece 20.
- the hollow cylindrical connecting piece 20 is welded to the tube wall 101 and is provided with a sealing seat 21 for supporting the flange 131 on the protective tube 13 and with an internal thread 22 for screwing in a clamping element 23 designed as a hollow screw 24.
- the hollow screw 24 serves to fix the exhaust gas probe in the connector 20.
- the exhaust gas probe with the protective tube 13 is passed through the end piece 20 and the insertion opening 19 in the tube wall 101 until the flange 131 rests on the protective tube 13 on the sealing seat 21.
- the hollow screw 24 pushed over the protective sleeve 11 and the housing 12 is now screwed with its external thread 241 into the internal thread 22, its end-side annular surface being placed on the flange 131 on the protective tube 13 and braced against the sealing seat 21.
- the banjo screw 24 carries a hexagon key 242.
- the exhaust gas probe shown in FIG. 2 is constructed in the same way as described, but with the difference that instead of the protective tube 13, the protective sleeve 11, which is also manufactured as a deep-drawn part, now carries an annular flange 111 which is integral with it.
- the flange 111 is of the one remaining after deep drawing
- Protective sleeve 11, housing 12 and protective tube 13 are in turn firmly connected to one another, preferably welded, and enclose sensor element 14. At the
- connection piece 20 ' here has an external thread 25
- the clamping element 23 is designed as a union nut 26 with an internal thread 261, with which the union nut 26 can be screwed onto the connection piece 20'.
- the union nut 26 has near its one end face a radial shoulder 262 which, after the union nut has been pushed on
- the exhaust gas probe with the protective tube 13 is again passed through the insertion opening 19 in the tube wall 101 until the flange 111 rests on the protective sleeve 11 on the sealing seat 21. Then the union nut 26 surrounding the protective sleeve 11 is opened the connection piece 20 'is screwed on until its radial shoulder 262 fixes the flange 111 of the protective sleeve 11' on the sealing seat 21. Otherwise, the structure of the exhaust gas probe according to FIG. 2 corresponds to that in FIG. 1, so that the same components are provided with the same reference numerals.
- the clamping element shown there as a union nut is designed here as a hollow screw 24 which, as in FIG. 1, can be screwed into the connecting piece 20.
- the flue gas probe is placed with the flange 111 on the protective sleeve 11 on the sealing ring 21 formed in the connecting piece 20, and is clamped against the connecting piece 20 when the hollow screw 24 is screwed in via the end face of the hollow screw 24.
- the use of the flange 111 obtained during deep drawing on the protective sleeve 11 as a clamping flange, as is the case in FIGS. 2 and 3, has advantages over the use of the flange 113 on the protective tube 14 as a clamping flange according to FIG. 1, since usually the Protective sleeve 11 is made with a greater wall thickness than the protective tube 13.
- FIGS. 4 and 5 of an exhaust gas probe mounted on the exhaust pipe 10 correspond almost completely to the exemplary embodiment of the exhaust gas probe described in relation to FIG. 1, with the exception that the cutting edge present after the deep-drawing process also remains on the protective edge made after the deep-drawing and is punched out or cut to, for example, approximately 1.5 mm from the outer sleeve contour.
- the flange 111 is used as a stop for the banjo bolt 24 and forms an anti-loss device for the banjo bolt 24.
- the protective sleeve is joined together 11 and housing 12, the banjo bolt 24 is pushed onto the housing 12 which is firmly connected to the protective tube 13.
- the protective sleeve 11 is then pushed over the end of the housing 12 and welded to the housing 12.

- a circumferential inclined shoulder 243 is formed, which, when the banjo screw 24 is axially displaced strikes on the housing 12 on the flange 111 of the protective sleeve 11.
- the exhaust gas probe is again guided with the protective tube 13 through the insertion opening 19 in the tube wall 101 of the exhaust gas tube 10 until the external thread 241 of the banjo bolt 24 engages in the internal thread 22 of the connecting piece 20. Then, by turning the hollow screw 24, the exhaust gas probe is displaced axially downward until the flange 131 rests on the protective tube 13 on the sealing seat 21 of the connecting piece 20. A further rotation of the hollow screw 24 leads to the non-positive clamping of the flange 131 on the sealing seat 21.

- the inner protective tube 27 is provided with gas passage holes 32.
- the inner protective tube 27, like the protective tube 13 and the protective sleeve 11, is produced as a deep-drawn part, the trimming edge present after the deep-drawing being left in all three deep-drawn parts and trimmed to a specific distance from the sleeve wall or protective tube wall.
- the outer region of the flange 131 on the protective tube 13 is used as a flanged edge 132.
- the middle section 143 of the sensor element 14 is fixed in the upper region of the inner protective tube 27 which takes over the function of the housing 10 and which has a slightly larger, clear diameter than the lower region of the inner protective tube 27, so that an annular one is formed at the transition between the two tubular regions Shoulder 272 results.
- a ceramic disk 28 is supported on this shoulder 272 and has a central through hole 29 for the sensor element 14.
- This seal 30 consists of melting glass or temperature-resistant putty or a foaming
- the ceramic disk 29 which consists, for example, of fosterite, prevents the melting glass from escaping or the putty from running out. If a foaming ceramic mass is used, then above the. Seal 30 fixed a second ceramic disc, which prevents the foam from being expelled during the baking process.
- the assembly comprising the inner protective tube 27 and the sensor element 14 fastened therein is inserted into the protective tube 13 such that the flange 271 of the inner protective tube 27 hangs on the flange 131 of the protective tube 13.
- the protective sleeve 11 is then placed over the connection-side end section 142 of the sensor element 14 received in the connector 16 and its flange 111 is placed on the flange 271 of the inner protective tube 27.
- the flanged edge 132 present on the flange 131 of the protective tube 13 is flanged onto the flange 111 of the protective sleeve 11.
- the tapered, end-side section of the protective sleeve 11 is pressed onto an elastic, plug-like molded part 31 which surrounds the connecting cable 17 to the connecting plug 16.
- the exhaust gas probe assembled in this way is mounted on the exhaust pipe 10 in the manner described in relation to FIG. 1, in that the protective tube 13 is in turn inserted into the exhaust pipe 10 through the insertion opening 19 in the connection piece 20 fastened to the pipe wall of the exhaust pipe 10 until the flange
- the exhaust gas probe to be prefabricated as a structural unit, which can then be inserted into the exhaust pipe 10 of the internal combustion engine on site.
- a welded connection between the deep-drawn parts is unnecessary both in the flanging and in the simple clamping, as a result of which the capital expenditure 'in production reduced and shorter cycle times are achieved in manufacturing.
- the invention is not limited to the described sensor, which is designed as an exhaust gas probe. It can be used in the same way with the same ' advantages for the manufacture of the installation sleeves of sensor elements in temperature sensors, pressure sensors and similar sensors.
- a temperature sensor is described for example in DE 37 33 192 Cl.
- a differently designed clamping element 23 can also be used instead of the hollow screw 24 or the union nut 26.
- the flange on the protective tube 14 or protective sleeve 11 does not itself have to rest on the sealing seat 21 of the connecting piece 20.
- the housing 12 can also lie on the sealing seat 21 with an inclined shoulder and bring about a gas-tight seal
- Clamping element 23 continues to engage the flange on protective sleeve 11 or protective tube 14 and creates a tension to connecting piece 20.
