Anhui Tiankang brand thermocouple is a type of thermocouple that, together with platinum resistance thermometers, accounts for about 60% of the total temperature sensor in the operation of this Tiankang thermocouple. Thermocouples used in industry are usually used in conjunction with display instruments, etc. The thermocouple products of this brand are divided into different specifications according to different electrode conductors. The two ends of the thermocouple are connected into a circuit. When the temperature of the junction is different, an electromotive force is generated in the circuit, which is called thermoelectric effect, and this electromotive force is called thermoelectric potential. Thermocouples use this principle for temperature measurement. The end directly used to measure the temperature of the medium is called the working end. When the material composition of the two thermocouple wires of the thermocouple is determined, the magnitude of the thermoelectric potential of the thermocouple is only related to the temperature difference of the thermocouple; If the temperature of the cold end of the thermocouple remains constant, the thermoelectric potential entering the thermocouple is only a single value function of the working end temperature.

In the current thermocouple manufacturing industry in Anhui, the main classification of this thermocouple is closely related to the material properties of the thermocouple. It is mainly divided into platinum thermocouple, platinum rhodium 13 thermocouple, platinum rhodium 30 thermocouple, nickel chromium nickel silicon thermocouple, nickel chromium copper nickel thermocouple, platinum rhodium 10 platinum thermocouple, iron copper nickel thermocouple, copper nickel thermocouple, platinum rhodium 30 platinum rhodium 6 thermocouple and other model series. The temperature measurement range of each thermocouple varies in its different application scenarios. Most thermocouple series products generally do not require compensation wires when measuring, and the influence of cold end temperature changes can be ignored; The long-term use temperature is 1600 ℃, and the short-term use temperature is 1800 ℃. Due to the small thermoelectric potential, a highly sensitive display instrument is required, which has the advantages of good bendability, strong measurement and seismic performance.
