补充资料：动圈仪表
一种小型模拟式显示仪表。动圈仪表常与热电偶、热电阻等配合，用来测量、监视和控制温度。它的测量机构是根据法国的A.de达松伐耳于1882年提出的检流计原理设计成的。由细导线绕成的可动线圈靠金属张丝或轴尖支承在永久磁铁极靴的间隙中（见图）。当电流通过可动线圈时感生磁场与永久磁场相互作用产生力矩,驱动线圈偏转,使张丝或游丝变形而产生反力矩，当二力矩平衡时指针稳定在某一位置。指针转角的大小与流过线圈的电流成正比，指针在标尺上指示出被测值。动圈仪表原理简单,成本较低,测量指示精确度较高。如附装能间歇地压下指针的落弓机构，则成为打点记录式仪表。还可在指针上加装一小铝旗，使其相对于另一电子振荡器的线圈移动，以改变振荡器的工作状态，从而使振荡器输出电流发生阶跃变化，再通过电子放大线路使控制继电器动作而起自动控制或报警作用。动圈仪表还可实现三位式、比例、比例积分微分调节。但由于测量机构是可动线圈，这种仪表不宜用于振动较大的场合，仪表的安装位置也受到一定限制。
