  • Patent number: 9404805
    Abstract: A composite material for a temperature sensor and a method of manufacturing the temperature sensor using the composite material are provided. The composite material contains four or more kinds of metal oxides combined with highly insulating materials to produce a material with semiconductor-like properties to more accurately measure a temperature at high temperatures in the range of 500° C. and above. The sensor includes electrode wires having a predetermined diameter inserted into the metal oxide of the temperature sensor when the metal oxide is press-molded to form the temperature sensor. Through the connection of the electrode wires to the temperature sensor device, disconnection of the electrode wires from the device even at a high temperature.

  • Patent number: 9243962
    Abstract: Disclosed herein is a composition of a sensor element, a temperature sensor having the composition of the sensor element and a method of manufacturing the temperature sensor. The sensor element composition comprising Y2O3, Al2O3, MnO2, NiO and Fe2O3, and further comprising ZrO2 and a temperature sensor comprising the same. The method comprising: weighing the composition for a sensor element; mixing the composition; calcining the mixture at about 1000° C.˜1400° C. for 30 min˜5 hrs; pulverizing the calcined mixture to obtain powder; disposing the powder type mixture into a mold; inserting in parallel a plurality of lead wires into the powder type mixture; pressure molding the powder type mixture; and sintering the pressure molded material at about 1300° C.˜1500° C. for 30 min˜5 hrs.

  • Publication number: 20130208764
    Abstract: The present disclosure relates to a composite material for a temperature sensor, and a method of manufacturing the temperature sensor using the same. The composite material according to the disclosure may contain four or more kinds of metal oxides that are combined with highly insulating materials, thereby producing a material with semiconductor-like properties that makes it possible to easily and accurately measure a temperature even at a high temperature in the range of 500° C. and above. Furthermore, unlike a conventional temperature sensors in which an electrode is printed/plated on the device surface, the sensor of the disclosure includes electrode wires with a predetermined diameter that are inserted into the metal oxide of the temperature sensor during a process in which the metal oxide is press-molded to form the temperature sensor so the electrode wires are prevented from becoming disconnected from the device.
