引言由于以往生产的XC系列动圈仪表存在不抗震,不能作快速调节,越限后不能作全量程指示,控制因易振动而失灵等缺点,近年来国内一些仪表生产厂家研制了多种带有前置放大器的XF系列动圈指示调节仪表,基本上解决了XC系列仪表存在的问题,但仍有某些不足,如仪表功耗太大、成本较高及缺乏线性电路温变漂移误差补偿措施等,为此我们设计与研制了
Introduction Since the XC series moving coil instruments produced in the past are not earthquake-resistant, they can not be adjusted quickly, and can not make full-range indication after exceeding the limit, and they have some shortcomings such as malfunction due to vibration. In recent years, some instrument manufacturers in China have developed a variety of Pre-amplifier XF series dynamic indicator adjustment instrument, basically solved the XC series instrument problems, but there are still some shortcomings, such as instrument power consumption is too high, the cost is high and the lack of linear circuit temperature drift compensation error compensation measures Etc., for which we designed and developed
