Electrostatic volt-meter OBC

TREK, INC., famous for its Electrostatic Voltmeters, is a world class manufacturer of custom on-board controllers (OBCs) for electrostatic voltmeter (ESVM) applications. These non-contacting on-board electrometers, commonly referred to as on-board controllers (OBC), have an operating mean time until failure rating of greater than 16,000 hours. These OBCs have been installed in the products of leading electrophotographic copier and printer manufacturers around the world. The Trek OBC employs a patented technique to perform the non-contacting measurement of the electrostatic voltage level of the photoconductor surface associated with electrophotographic processes. The non-contacting technique allows high stability voltage measurement to be made while the photoconductor surface is moving. High measurement accuracy is maintained even if the OBC measurement probe to photoconductor surface distance varies due to mechanical run-outs. The non-contacting method also insures that no charge transfer to the probe occurs which would cause disruption of the surface voltage. These OBCs can also be used in ESD applications to identify sources of charge generation.
