Abstract: Method for the manufacture of a temperature sensor with a thermocouple comprising the following successive steps: a) introduction, in a support tube made of a ceramic material, of two thermocouple wires until they extend beyond said support tube; b) welding the ends of said thermocouple wires extending beyond said support tube so as to form a thermocouple hot point; c) introduction, at least partially, of the support tube into a reinforcement tube made of a stainless steel; d) fixing a cap onto said reinforcement tube so as to protect said hot point.

Abstract: The invention relates to a method for manufacturing a temperature sensor with a thermocouple, which includes the following consecutive steps: a) manufacturing a cable with mineral insulator (14) including two thermocouple wires (10, 12) extending along the entire length of the cable with mineral insulator and embedded in a mineral insulator (8); b) stripping one of the ends of the cable with mineral insulator over a length of 2 to 20 mm, preferably less than 15 mm, preferably less than 10 mm, such as to expose the ends of the thermocouple wires; c) connecting the ends (40, 42) of the thermocouple wires thus exposed, such as to constitute a thermocouple hot spot (13); and d) attaching a cap (20) to said cable with mineral insulator so as to protect said hot spot.
