Zusammenfassung:A temperature sensor for measuring vehicle exhaust gas, produced by means of the production method according to the present invention, has a temperature element joined to one end of an insulated cable, and the core wire portion to which the temperature element is joined is oxidized at a high temperature, and thus oxygen that is supplied at the other end of the cable is sufficiently supplied to the temperature element without any loss, and thus even at high temperatures of around 1000°C, defects such as element degeneration, thermal deformation or corrosion do not occur, and accuracy can be increased. L'invention concerne un capteur de température servant à mesurer un gaz d'échappement de véhicule, produit au moyen du procédé de production selon la présente invention, comportant un élément de température relié à une extrémité d'un câble isolé, et la partie de fil d'âme à laquelle est relié l'élément de température est oxydée à une haute température, et ainsi l'oxygène fourni à l'autre extrémité du câble est suffisamment fourni à l'élément de température sans aucune perte, et donc, même à des hautes températures d'environ 1000 °C, il n'y a pas d'apparition de défauts tels qu'une altération, une déformation thermique ou une corrosion d'élément, et la précision peut être augmentée. 본 발명에 따른 제조방법으로 제조된 자동차 배기가스 측정용 온도센서는 절연 케이블의 일단에 온도소자를 접합하되, 상기 온도소자가 접합된 심선부를 고온에서 산화시킴으로써 케이블의 타단에서 공급되는 산소가 손실 없이 온도소자까지 충분히 공급되도록 하여 1,000℃ 내외의 고온에서도 부식이나, 열변형, 소자변성 등의 불량이 발생하지 않으면서도 정확도를 높일 수 있다.
