S3——distance regulator: the sensor should be placed on the calibration device to extend out the front end. The
geometrical shape and materials of the support should minimize the impact on the distribution of the electrical
field around the front end of the sensor.
VII. Product Performance
The test data of the standard plate electrode is as follows:
The static voltage values under 3 groups of test distances were detected. The standard plate electrode was
600mm*600mm stainless steel electrode. The test distance was the distancebetween the surface of plastic
shell to that of the plate electrode on one side of the detection window of the electrostatic sensor. The light
grey heavy line in the figure is the calibration voltage line when the slope is 1.
