Temperaturfühler

摘要

The invention relates to a temperature sensor for determining the temperature of a medium, especially the exhaust gases of an internal combustion engine, comprising a resistance track (11) which contains a cermet and is disposed on a substrate (12), said resistance track consisting of a conducting area (13) and a measuring area (15). The conducting area (13) of the resistance track (11) has a lower electrical resistance than the measuring area (15). The electrical resistance of the measuring area and conducting area (13, 15) is adjusted by the percental proportions of the material components of the cermet.
