Q.Are there any documents that give an outline of surface potential sensors EFS series?
Sensors and Sensor Systems > Sensors and Sensor Systems > Surface Potential Sensors
A. The EFS series surface potential sensors are compact, lightweight, and allow stable operations due to their tuning fork structuring that has been optimized for sensing the surface potential of charged drums. Furthermore, the sensors have a unique feedback circuit that gives the probe parts the same potential as measured by the sensor. This eliminates dependence on detection distance and ambient environments, thus enabling high-accuracy potential detections. Please refer to the available product overview that explains the products and technology in the EFS series.
