摘要
在温度测量的场合 ,传感器输出的电压或电流等信号往往较弱 ,而且其中还可能含有工频、静电和磁耦合等共模干扰 ,采集工作就需要用特殊的手段来实现 ,否则就会在测量结果中带来较大的误差。为了提高温度测量精度 ,从硬件和软件 2个方面进行了论述 ,提出了可行的方法。由该方法设计的应用系统性价比较高 。
In temperature measurement, the signals of voltage and current of a transducer are always faint and there also may exist interference, so special means should be taken when performing measurement tests. In order to improve temperature metrical precision, a practical method is presented based on hardware and software analysis. A temperature measuring system is designed using this method, which can satisfy the requirements of temperature measuring tests.
