ABSTRACT:
A simpler, multiple element chip detector having two parallel, electrical conductors shrouding a plurality of discrete magnets which are aligned along the longitudinal axis of the chip detector is provided. The poles of each magnet abut opposite conductors defining a chip gap. A plurality of electrical isolators are mounted about the conductors and positioned between each of the magnets to define a chip element therebetween. The number of chip elements can be varied by adding or subtracting a magnet and isolator. The conductors are mounted in a housing to receive an electrical potential. Thus, regardless of the number of chip elements no additional circuitry is required. In an alternative embodiment the discrete magnets are replaced with a single magnet. In this embodiment the number of chip elements can be increased or decreased by only adding or removing an isolator.
