Apparatus and Method for In-Field Magnetic Measurements

摘要

A magnetic field verifier apparatus includes a magnetic field detection element configured to produce a voltage signal in response to an applied magnetic field wherein the voltage signal corresponds to the strength of the applied magnetic field. Substantially identical circuit boards or units are connected to a central unit or mother board to place magnetic field detection elements of each board or unit in an mutually approximately orthogonal relationship. A microcontroller is in communication with the voltage signal. The magnetic field verifier apparatus is configurable to sense particular field strengths at various frequencies and store the readings to provide the user with a reliable verification that a particular magnetic field strength has been produced in a particular environment.
