For the protection tube, we adopt 99% high-purity corundum (alumina ceramic), which features excellent high-temperature resistance, thermal shock resistance and corrosion resistance. It is free of impurity pollution, suitable for oxidizing and inert atmospheres, and can be used in vacuum environments for a short time (reducing atmospheres are prohibited) <superscript:8>. This design effectively inhibits the degradation of platinum-rhodium alloy at high temperatures and ensures long-term stable operation <superscript:6>.
Five Core Advantages, Leading Ultra-High Temperature Measurement
Compared with S/R type single platinum-rhodium thermocouples, Duchin Type B thermocouple has more outstanding performance, perfectly adapting to various harsh high-temperature working conditions:
Ultra-High Temperature Adaptability: Long-term operating temperature up to 1600℃, short-term maximum temperature up to 1700℃, covering most industrial ultra-high temperature scenarios, which is an ideal choice for high-temperature measurement up to 1700℃ <superscript:3>.
High Precision & Stability: Class Ⅱ accuracy (tolerance ±1.5℃ or ±0.25%|t|); it has extremely strong oxidation resistance at high temperatures, minimal thermoelectric characteristic drift, and its service life is far longer than that of ordinary thermocouples <superscript:8>. Its low thermoelectromotive force at room temperature can almost ignore the impact of reference end temperature changes, eliminating the need for compensation wires<superscript:6>.
Reliable & Durable Structure: The high-purity corundum protection tube completely prevents high-temperature pollution, has good thermal shock stability, and is suitable for continuous industrial production, effectively ensuring the consistency of product quality in mass production.
Excellent Anti-Interference Ability: The dual platinum-rhodium alloy structure has better anti-pollution ability than S/R type single platinum-rhodium thermocouples, making it suitable for complex working conditions such as scientific research and industrial high-temperature furnaces <superscript:2>.
Flexible Customization: Standard length L=180mm; we can customize the length and installation method according to customer needs to adapt to different equipment interfaces, providing personalized solutions for various industrial equipment <superscript:9>.
