Abstract
The invention relates to a method for producing a high temperature sensor, in particular a high temperature sensor for measuring the exhaust gas temperature of motor vehicles, comprising a sensor element and a protective tube which at least partially surrounds the sensor element. Said protective tube is closed on the hot side of the high temperature sensor by a shaping method, in particular molding.
Claims16
A method for producing a high-temperature sensor (10) for measuring the exhaust gas temperature of motor vehicles, comprising a sensor element (2) and a protective tube (5) surrounding the sensor element (2) at least partially, wherein the protective tube (5) is closed on a hot side of the high-temperature sensor (10) by a pressing process and the protective tube (5) is pressed such that the protective tube (5) has two tip-shaped sections (11a) after the pressing, and wherein the two tip-shaped sections (11a) are thin tips projecting axially from a pressing section (11) and together defining a constricted region (11b) therebetween.
A high-temperature sensor (10), for measuring the exhaust gas temperature of motor vehicles, comprising:
- a sensor element (2);
- and
- a protective tube (5) surrounding the sensor element (2) at least partially, wherein the protective tube (5) is closed on a hot side of the high-temperature sensor by a pressing process, and the protective tube (5) is pressed such that the protective tube (5) has two tip-shaped sections (11a) after the pressing, and wherein the two tip-shaped sections (11a) are thin tips projecting axially from a pressing section (11) and together defining a constricted region (11b) therebetween.
