利用差动电容变换器测量位移的方法,已知的有多种。变换器的动片与移动的目标为传动连接;其中使用最广的一种方法是以变换器作为电容分压器。图1a 引述的是实践中常迂到的一种电容分压器的不平衡桥式电路,差动电容器片间的离是可变的(对电容器片的重叠面积可变的变距换器而言,所述结论都是正确的,故不单独对它加以探讨)。图中符号:Γ——交变电压发生 There are many known methods for measuring displacement using a differential capacitance converter. The converter’s moving piece and the moving goal are the transmission connection; One of the most widely used methods is to use the converter as the capacitive voltage divider. Figure 1a cites an unbalanced bridge circuit of a capacitive voltage divider, which is often practiced in practice. The distance between the differential capacitor plates is variable (for a variable area variable capacitor of a capacitor plateau ), The conclusion is correct, so it is not discussed separately. Symbol in the picture: Γ - alternating voltage occurs
