Temperature digital display meter 温度数显表
Model dcw light - spot vectormeter , designed to from a complete set with a dynamic balabcing tester , is served as a display meter for phases and ampiltudes of dynamic unbalancing quantites . the meter is composed of two sets of measuring mechanisms in moving coil system , and is also put to use lightspot indication as well as polar scale Dcw型光点矢量表是供动平衡试验机配套作为动态不平衡量的相位和幅值的显示仪表,它是由2组磁电系测量机构组成并采用光点指示及极坐标标度。
Abstract : based on analysis of the operational principle of the traditional inductosyn digital display meter in the paper , the contradiction between detecting resolution ratio and antidisturbance ability is discovered . and then , to resolve the contradiction , the method of demodulation technology and high frequency excitement technology being used is advanced 文摘:通过分析传统鉴相型数显表的工作原理,揭示了其检测分辨率与抗干扰能力之间的矛盾,并提出了采用差频解调和高频激磁等技术解决矛盾的方法。
