Problems solved by technology

Existing gas path test methods cannot provide stable charged objects to quantitatively characterize the performance of electrostatic sensors; the position of electrostatic sensors cannot be adjusted flexibly, and it is difficult to obtain the corresponding relationship between the induction characteristics of electrostatic sensors and structural parameters; Affected by the environment, the existing test conditions are difficult to carry out comparative testing of different electrostatic sensors under the same experimental conditions. These defects have greatly hindered the optimal design of the electrostatic sensor structure, the improvement of the performance of the electrostatic monitoring system, and the analysis and processing of the induction signal of the electrostatic sensor. It is one of the main problems to be solved urgently in the electrostatic monitoring system to realize the stable and convenient comparative test and quantitative test of the performance of the electrostatic sensor
