1. An apparatus for measuring the magnitude of an electrostatic field, comprising:

  • a balanced beam adapted to vibrate about a support at a midpoint thereof;

    an electrode operatively associated with said balanced beam and electrically insulated therefrom, said electrode moving in unison with said balanced beam in the electrostatic field to produce a high voltage biased signal;

    a high voltage signal processing circuit; and

    a multi-stranded conductor for electrically connecting the electrode to the high voltage signal processing circuit, said high voltage signal processing circuit generating, in response to the high voltage biased signal, a second signal, having a lower voltage than the high voltage biased signal, in proportion to the magnitude of the electrostatic field.
