随着工业自动化的发展,在流量,转速等测量上都要求将一个与被测量成比例的频率信号转换成统一的高电平直流信号,送给调节器或显示、积算仪表,组成相应的控制系统。DZP-_(03)~(02)型频率转换器(下称仪表)是DDZ-Ⅱ型电动单元组合仪表中的一个转换单元。它将某些流量传感器(如涡轮流量计、椭圆齿轮流量计、或转速计)的输出频率信号转换成统一的电流信号。由于检测频率信号的传感器简单可靠、线性好、转换精度高、量程范
With the development of industrial automation, the flow, speed and other measurements require a frequency proportional to the measured signal is converted to a unified high-level DC signal sent to the regulator or display, integrating instruments, the formation of the corresponding Control System. DZP -_ (03) ~ (02) frequency converter (hereinafter referred to as instrument) is DDZ-Ⅱ type electric unit combination instrument in a conversion unit. It converts the output frequency signals of some flow sensors (such as turbine meters, oval gear meters, or tachometers) into a single current signal. As the sensor signal frequency detection is simple and reliable, good linearity, high conversion accuracy, range
