| 摘 要： | 阐述了采用电热转换方法测量电流的基本原理，介绍了利用电热带和热电阻构成的传感器。通过对传感器静、动态特性分析可知，电流与温度的关系为单值但非线性，灵敏度、迟滞误差及重复性既可以满足一般测量要求。其动态特性为一阶惯性环节，并求得了时间常数。对开发电热转换传感器提供了一些有益经验。

| Abstract: | The basic principle on electrical current measurement by electro-thermal conversion was enunciated and a kind of sensor which was made of electric wire and resistance was introduced.After the static and dynamic state characteristics of the sensor was analyzed,it can be known that the relationship of electric current and temperature was of single value,but wasn't of linearity.The general measure request of the sensitivity,lag error and repeatability was satisfied.The characteristic of dynamic state was the first order inertia link,and get the time constant.The experience gained hereby was beneficial to developing electro-thermal conversion sensor. |
