电磁式仪表的温度补偿

指出磁电式仪表虽然受温度影响不大,但随着周围环境温度的变化,也要引起一些环境误差,本文从其工作原理上分析产生附加误差的原因,并列举补偿这一误差的方法。通过对几种方法的比较,认为线路补偿法最适合。然后,通过具体例子着重介绍分析了该补偿法的接线方式、工作原理、补偿效果和使用范围。

Temperature compensation of electromagnetic instrument

It points out that although the electromagnetic instrument is not greatly influenced by the temperature, but with the change of the environment temperature, it will cause some environmental error. It analyzes the cause of the additional error from the working principle, lists the error compensation methods. By comparing some methods, it points out that circuitry compensation method greatly fits well. Then, it introduces and analyzes the connection method, working principle, as well as compensation effect and application range of the compensation method by concrete examples.
