ABSTRACT:
A multilayer tape probe for measuring the movement of charge has at least a pickup electrode comprising one layer of electrically conductive tape and a shield electrode comprising another layer of electrically conductive tape, the pickup and shield electrodes being separated by a dielectric strip. Circuitry is connected to the probe to drive the shield electrode and to monitor the potential difference between ground and pickup electrodes and actuate an alarm if an unwanted charge is present.
