1/4桥路应变采集的温度补偿效果实验研究
Experimental Research on Temperature Compensation Effect of 1/4 Bridge Circuit Strain Acquisition
摘要
Abstract
The temperature compensation principle of constant voltage exciting strain gauge and constant current exciting strain gauge is illustrated, and the temperature compensation experiments of different structural members using different strain gauges are designed. It indicates that the strain transducer of temperature compensation is failed and no better than ordinary resistance to eliminate the influence of temperature. However, it can be neglected in the short-term experiment, if the strain due to unit temperature change is smaller than the linear expansion coefficient of specimen.关键词
