直接校准型高温电阻应变计的研究

A Study of a Directly-Calibrated High-temperature Resistance Strain Gage

为消除高温电阻应变计热输出分散性,提高测试精度,避免现场测试失败,研制了一种新型高温电阻应变计——直接校准型高温电阻应变计。实验获得满意结果。为高温零、部件应力测量提供了一种新的、可靠的元件和方法。

To eliminate the heat output dispersion of high-temperature resistance strain gages, enhance measurement precision and avoid on-site measurement and testing failures, the authors have developed a new type of high-temperature resistance strain gages which feature direct calibration. The satisfactory test results show that such strain gages have met the nee(?)s of providing a new and highly reliable method for the stress measurement of high-temperature elements and components.
