Polyester-Insulated T2 Thermocouple Wire (Ni95/(Al+Mn+Si)5)

Polyester-Insulated T2 Thermocouple Wire (Ni95/(Al+Mn+Si)5) combines the high-temperature stability and thermoelectric performance of nickel-based thermocouple alloys with the dielectric and chemical resistance of a polyester coating. Designed for demanding temperature sensing applications, it maintains accuracy and insulation integrity under extended thermal cycling and exposure to industrial atmospheres. Industries such as aerospace, power generation, and metallurgical processing rely on it for temperature measurement in gas turbines, smelters, and heat-treatment systems. Specific uses include embedded thermocouples in aerospace engines, precision thermal mapping in industrial kilns, and control systems for metallurgical refining. In research, it is critical for evaluating thermoelectric behavior, insulation performance at high heat, and long-term stability under fluctuating loads. Its combination of measurement precision, heat resistance, and coating durability ensures dependable service in extreme thermal monitoring.
