Signal Quality of Dual-tip Electrical Conductivity Probe for Measurement of Bubble Parameters
双探针电导探头测量气泡参数的信号质量

A dual-tip conductivity probe for measurement of bubble parameters in a gas-liquid flow was studied.The effects of the probe structure,measurement circuit and sampling method on the bubble signal quality measured with the probe were investigated,and the measures to improve the signal quality were proposed.The experimental results show that the signal response is faster when the conductive length of probe tips is smaller.This effect becomes insignificant when conductive length is smaller than 0.025 mm.The pr...
