DQ—200型电气转换器和DQ—100-样,都是将标准的直流信号0~10mA转换成标准的气压信号0.2~1.Okgf/cm~2,构通DDZ电动单元和QDZ气动单元而混合使用。 DQ—200电气转换器和DQ—100电气转换器,都是按力补偿式原理设计的。一构成力补偿测量原理的条件从传递函数关系上有: P/I=K_1·K_2/1+K_2K_3=K_1K_2/1+K_2K_3 若检零元件灵敏度高,放大器放大倍数高即K_2很大
DQ-200-type electrical converters and DQ-100-like, are the standard DC signal 0 ~ 10mA converted into a standard pressure signal 0.2 ~ 1.Okgf / cm ~ 2, structure through the DDZ electric unit and QDZ pneumatic unit and Mixed use. DQ-200 electrical converter and DQ-100 electrical converter, are based on the principle of force-compensation design. A composition of the principle of force compensation measurement conditions from the transfer function relationship: P / I = K_1 · K_2 / 1 + K_2K_3 = K_1K_2 / 1 + K_2K_3 If the zero detection element sensitivity, the amplifier high magnification K_2 is large
