Strong anti-interference type electrostatic induction method pipeline dust concentration detection device and method

The invention relates to a strong anti-interference type electrostatic induction method pipeline dust concentration detection device and method, and belongs to the technical field of dust concentration detection. The device comprises a rotating body, an insulator, and an insulating sleeve, a metal shielding body and a detection electrode which are wrapped in the insulator, the rotating body covers the insulator; the detection electrode is clamped between the insulation sleeve and the insulator; the insulation sleeve wraps the periphery of the metal shielding body to isolate the detection electrode from the metal shielding body; the metal shielding body is grounded through a wire. One end of the detection electrode is suspended to detect dust particles passing through the gap between the shielding bodies, and the other end is connected with the signal processing circuit. The precision and stability of the pipeline electrostatic induction method dust concentration sensor are improved. 本发明涉及一种强抗干扰式静电感应法管道粉尘浓度检测装
