Setting a double tube, comprises e.g. pushing inner tube to base body, pushing outer tube to inner tube and base body, and spacing base body side ends of both outer- and inner tube in direction of outer side of base body by distance

摘要

Setting a double tube (12) comprising an outer tube (14) and an inner tube (16) on a base body (18) by a compound, which is produced by a welding, comprises (i) pushing the inner tube to the base body, (ii) pushing the outer tube to the inner tube and the base body, (iii) spacing the base body side end of the outer tube and the base body side end of the inner tube in the direction of the outer side of the base body by a distance, (iv) welding the base body side end of the inner tube to the base body, and (v) welding the base body side end of the outer tube with the inner tube. Setting a double tube (12) comprising an outer tube (14) and an inner tube (16) on a base body (18) by a compound, which is produced by a welding, comprises (i) pushing the inner tube to the base body, (ii) pushing the outer tube to the inner tube and the base body, (iii) spacing the base body side end of the outer tube and the base body side end of the inner tube in the direction of the outer side of the base body by a distance, (iv) welding the base body side end of the inner tube to the base body, and (v) welding the base body side end of the outer tube with the inner tube, where the double tube is pushed at least on a cylindrical section (20) of the base body. An independent claim is also included for a measuring sensor, preferably gas sensor for determining a physical property of a measurement gas, preferably the temperature or concentration of a gas component in the exhaust gas of an internal combustion engine, comprising the base body and the double tube having the outer tube and the inner tube, which is fixed to the base body, where the double tube is fixed on the base body by the above mentioned method.
