1.工业电导仪的工作原理工业电导仪的原理结构如图1。图中的∑点为运算放大器的虚地点。对∑点:V/R=-V_■R_1∴V_■=-(V)/(R)R_1R=(1)/(x)K=σK式中:R——电导池两电极间的电阻
1. Industrial conductivity meter working principle Industrial conductivity meter principle structure shown in Figure 1. Σ point in the figure for the op amp virtual location. To Σ point: V / R = -V_ ■ R_1∴V_ ■ = - (V) / (R) R_1R = (1) / (x) K = σK Where: R-- cell resistance between the two electrodes
