To improve sensitivity and linearity, feedback loop was adopted with electrostatic in detection and managing circuit, which is fabricated with high precision bipolar linear circuit technology.
A detector array is disposed with laying a shield cylinder around each detection electrode. Feasibility of detection of electrostatic volume target by this system has been validated.
This measuring instrument for electrostatic charge of particles can realize the real-time , on-line and remote detection of electrostatic charge of particles.
