Application Summary AI generated
GB/T 4990-2010 specifies the chemical composition, electrical resistivity, and thermoelectric stability requirements for alloy wires used in extension and compensating cables for thermocouples. It is applied in industrial temperature measurement systems, particularly in metallurgy, chemical processing, and power generation, where accurate signal transmission from thermocouples to instruments is critical. The standard ensures that the compensating wires match the thermoelectric properties of specific thermocouple types, minimizing measurement errors in high-temperature or harsh environments.
