Abstract
A method and apparatus for the accurate non-contact detection and measurement of static electric charge on an object using a reciprocating sensing probe that moves relative to the object. A monitor measures the signal generated as a result of this cyclical movement so as to detect the electrostatic charge on the object.
Claims8
An apparatus for the detection and measurement of static electric charge on the surface of a charged object comprising:
- a sensing probe, said probe being positioned a specific distance from the surface of the object;
- a motor means, connected to the sensing probe, for providing cyclic movement to the sensing probe so as to cyclically move the sensing probe relative to the surface of the object;
- the motor means includes a clock motor, said clock motor connected to a wheel so that the motor rotates the wheel;
- and
- a monitoring means, connected to the sensing probe, for monitoring the potential of the charged object.
