Thermocoupl
Thermocoupl products, which are used to heat the surfaces of two separate metal combinations to generate electric current, are usually used for temperature measurements in high temperature furnaces. Thermocoupls produced with longevity have reliable properties that can operate within different uses and systems for many years when installed correctly. Thermocoupls are needed to measure temperature levels within industrial, scientific and mechanical applications. Thermocouples are also frequently used in different industrial areas such as energy production, oil, gas, pharmaceuticals, construction and cellulose.
Techincal Information
Regardless of the temperature distribution of the hot point and cold point in thermocouples, the voltage produced is proportional to the temperature difference between the hot and cold points. The temperature difference between the hot spot and the cold spot creates a voltage (EMF) on the resistor. Different temperatures are read when the cold spot temperature changes, provided that the hot spot temperature remains the same. For this reason, in order to provide a standard for the values in the mV tables, the mV values for the measured temperature are obtained by keeping the cold point at 0 °C. Thermocouples are widely used for measurement and control at various temperatures from -200° to 2320°C. It also converts the temperature gradient into electricity.
In the production of thermocouples, there are many parts from direct connection caps to inner protectors, from protective tubes to insulators, flanges and records. When flange and union, connection cap, and insulator are diversified together with the inner protectors called primers and protective tubes, the resistance types also vary. Thermocouples are preferred in many fields due to their low cost. A There are thermocouple types available for use in the application formed by the combination of copper and Konstantan, while there are also thermocouples formed by the combination of iron and Konstantan, nickel chrome and nickel, chromium and contrast thermocouples, chromel – alumel type and lastly platinum radium – platinum resistance.
