利用差压变送器检测流量

Using Transducers of Differential Pressure to Measure Flux

采用差压变送器直接测量流量,输出电流与被测流量将是非线性关系。若在差压变送器的电磁反馈机构中串接一个电流平方器,就会使输出电流与被测流量呈线性关系,便于显示、记录、调节。为此设计了一个由分离元件构成的电流平方器电路,就能解决非线性问题。

By using transducers of differential pressure to measure flux directly, the relation between current output and measured flux will be nonlinear. When connected in series a squarer to electromagnetism feedback system of differential pressure their relation will be linear, which is convenient to display, record and adjust. So if circuits of current transducers are designed with resolution elements, nonlinear problems will be solved.
