Slow Temperature Response? Si₃N₄ Thermocouple Protection Tubes Deliver Fast and Accurate Temperature Measurement

2024-05-06
Latest company news about Slow Temperature Response? Si₃N₄ Thermocouple Protection Tubes Deliver Fast and Accurate Temperature Measurement

In non-ferrous foundries, accurate temperature control is critical for casting quality. Conventional graphite or cast-iron thermocouple tubes degrade rapidly in molten aluminum, slowing response and increasing error.
The Silicon Nitride Thermocouple Protection Tube offers a high-performance solution with thermal conductivity above 25 W/m·K, density ≥ 3.2 g/cm³, and exceptional corrosion resistance.

Made by hot-isostatic pressing, it withstands continuous immersion at 800–1000 °C without reacting with molten metals.
Field tests show that Si₃N₄ tubes improve response speed by 40 % and maintain temperature accuracy within ±2 °C, while service life extends 3–5 times compared with graphite tubes.
They are now widely used in aluminum smelters, die-casting plants, and copper refining lines, ensuring faster, cleaner, and more reliable temperature measurement for intelligent process control.
