| 中文摘要: |
| 针对常规铱铑-铱热电偶负极铱在测试过程容易断裂的问题，提出了采用双铱铑合金热电偶改善其机械性能的方法，并用高温热电偶校准装置对IrRh40-IrRh10热电偶的热电特性进行了研究和验证，表明其热电特性线有良好的线性，灵敏度约为3μV/℃。利用该类型热电偶制作的气流温度传感器，适用于发动机及导弹等武器装备研制试验中高温气流温度的测量。 |
| 英文摘要: |
| A high temperature measurement method of bi-alloy of iridium and rhodium was put forward to solve the fracture problem of negative pole of conventional iridium-rhodium thermocouples. The experimental results on a high temperature calibration device show that the IrRh40-IrRh10 thermocouples have good linearity, and the sensitivity is about 3 uV/ C. An air temperature probe made by this type of thermocouples is suitable for measurement of high-temperature air flow in the engine development. |
