Abstract
A panoramic electrostatic field sensor includes a central monitoring electrode for detecting an electrostatic field oriented about a 360.degree. arc peripheral thereto. An apertured housing is concentrically arranged about the monitoring electrode, the housing having circumferentially spaced windows through which the central electrode can 'see' any electrostatic field radially disposed with respect to the sensor. A cylindrical shielding cap is rotated in the annular space between the monitoring electrode and the housing, the cap incorporating at least one slot to expose the monitoring electrode periodically to any fields viewed through the housing windows. Electronic means for measuring the voltage in response to the field detected is adapted to activate a static neutralizer for emission of positive and negative ions into the field or to actuate a variety of peripheral indicating or triggering devices which provide signals, alarms or readout functions.
