Application Note

Thermocouple extension wires are crucial in industries like aerospace, chemical plants, oil and gas, power plants, steel mills, aluminum foundries, pulp and paper, wastewater treatment, and heat treatment. They enable accurate temperature measurements by transmitting signals from thermocouples to controllers. In aerospace and oil & gas, they ensure reliable temperature monitoring in harsh environments. In power plants and steel mills, they optimize process control, while in wastewater and heat treatment, they ensure precise temperature regulation. Using high-quality extension wires improves system accuracy, reliability, and performance in these critical applications.
