The thermocouple wire is the core component of a temperature sensor and cannot measure temperature itself. The principle is the thermoelectric effect, which means that one end of two different pieces of metal is welded together. When the welding point is heated to a certain temperature, a significant potential is generated at both ends. The voltage is measured by a pressure measuring instrument and the temperature is calculated. Tungsten rhenium thermocouple wire, used as a material for high-temperature thermocouples and cathode wires. Tungsten rhenium alloy has good electrical properties, ductility, and processability, and the wire can be used for high-temperature thermocouples and cathode wires. Used in vacuum, hydrogen, and inert atmospheres, with a temperature range of 0-2300 ℃. The uneven thermoelectric electromotive force of the positive or negative electrode of the entire coil (coil) of thermocouple wire shall not exceed 40-80 at 1200 ℃ μ V. Raw material preparation - raw material separation - mixing - reduction treatment - second mixing - pressure sintering - rotary forging, drawing processing - finished product
