Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] The fast-response thermocouple disclosed in the present invention includes two thermocouple wires 3, the materials used for the two thermocouple wires are NiCr alloy and NiSi alloy respectively, the thermocouple wires are located in the protective sleeve 1, and the sleeve is filled with insulating material 2, The two thermocouple wires are connected by a metal joint 5 at the hot end, and there is an insulating pad 4 between the metal joint and the casing.
[0020] When measuring temperature, such as measuring the temperature of an aluminum alloy low-pressure casting mold, the metal joint is directly inserted into the temperature measuring hole of the mold to contact the mold wall, and the heat is directly transmitted to the metal joint through the mold wall during temperature measurement. At this time, the metal joint and The contact poi...
