Title:
METAL-OXIDE SINTERED BODY FOR TEMPERATURE SENSOR, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/169064
Kind Code:
A1
Abstract:
The present invention relates to a metal-oxide sintered body for a temperature sensor, which can be installed in a combustion engine and components connected to the engine in order to sense temperature, as well as to a method for manufacturing same. The metal-oxide sintered body uses metal oxide, which may sense the temperature over a wide range of temperatures and exhibit high resistance characteristics. The metal-oxide sintered body manufactured by the method of the present invention has particles with large resistance values and particles with small resistance values mixed therein, and therefore the particles with the small resistance values may serve as a main resistance component in the temperature range of 0°C to 500°C, and the particles with the large resistance values may contribute to the total resistance in proportion to the mixing ratio in a high temperature range of 500°C to 900°C, to thereby increase the total resistance value. Thus, the metal-oxide sintered body of the present invention enables a single sensor to measure all resistances, i.e. to measure temperatures in the temperature range of 0°C to 900°C, and therefore can be used in an exhaust device or the like of a motor vehicle that requires temperature measurement over a wide range of temperatures.
