Each Charged Plate Monitor Offers High Accuracy and Flexibility in Plate Size and Capacitance, Ideal for ESD Applications
Trek Charged-Plate Monitors employ a revolutionary charged plate monitor design that utilizes an ultrahigh-impedance, high-voltage follower to monitor the ion collecting plate voltage. This technique provides very high accuracy and virtually infinite impedance loading of the plate, while allowing the ion collecting plate to be charged and monitored through the same small-diameter connection. This technique also makes the measurement capacitance independent of the physical size and shape of the ion plate. Therefore, the size and shape of an ion collecting plate, as well as the measurement capacitance, may be customer specified to match a particular ESD-sensitive device within a manufacturing process. Charged Plate Monitors can be used for ionizer testing, ionizer maintenance and other ESD applications.
