    • A temperature sensor for use in a heating apparatus is disclosed. The temperature sensor includes a rigid cylindrical body and upper and lower plates disposed at one end of the rigid cylindrical body. A first electrical insulator is interposed between the upper and lower plates and has a recess filled with a second electrical insulator, in which a hot junction of a thermocouple is buried. Since the respective components are just in contact with each other without any bonding therebetween, there arises no stress in the temperature sensor even at high temperatures. Furthermore, even if a short circuit occurs in the thermocouple, data indicating the short circuit is output from the temperature sensor to the control system of the heating apparatus, thereby assuring safety in the operation of the heating apparatus.
    • 公开了一种用于加热装置的温度传感器。 温度传感器包括刚性圆柱体,并且设置在刚性圆柱体的一端的上下板。 第一电绝缘体插入在上板和下板之间,并且具有填充有第二电绝缘体的凹部,其中热电偶的热连接被埋入其中。 由于各个部件彼此之间没有任何接合而彼此接触,所以即使在高温下也不会在温度传感器中产生应力。 此外,即使在热电偶中发生短路,表示短路的数据从温度传感器输出到加热装置的控制系统,从而确保加热装置的运行的安全性。
