Polyester-Insulated T1 Thermocouple Wire (Ni90/Cr10)

Polyester-Insulated T1 Thermocouple Wire (Ni90/Cr10) combines the high-temperature sensing capabilities of type K thermocouple-grade nickel-chromium alloy with the dielectric protection and chemical resistance of a polyester coating. It offers reliable temperature measurement in harsh environments, with stability across extended thermal cycles. Industries including aerospace, metallurgy, and energy generation use it for temperature monitoring in furnaces, turbines, and industrial reactors. Specific applications include embedded temperature sensors in jet engines, high-precision furnace control loops, and continuous casting process monitoring. In research, it is employed for thermal response characterization, high-temperature sensor design, and insulation performance testing under rapid temperature fluctuations. Its balance of mechanical durability, signal stability, and thermal resistance ensures dependable performance in extreme heat measurement applications.
