Model PD04002A Charged Plate Monitor Controller utilizes standard, custom and wide-temperature range charged plates. The compact design features exceptional accuracy and stability and features a voltage monitor output for remote monitoring. The Model PD04002AP Hi-Temperature Charged Plate (pictured) is a 25 mm x 25 mm (1" x 1") with an operating range of -60° to 160° C.
The Trek Model PD04002A is a versatile microprocessor based charged plate monitor which is ideally suited to monitor the performance of air ionizers that are used in critical wide temperature operations associated with semiconductor, LCD, electronic assembly, and other processes where static charge accumulations pose a threat to production yields and/or product quality.
The Model PD04002A utilizes a new technique which requires less than 0.1 picoampere of ion field current to achieve full accuracy and stability. Other product designs require up to 2000 times more ion current to be drawn from the ion field to achieve stability.
The ultra sensitivity of the Model PD04002A makes this product the ideal choice in air ionizer monitor applications where small area ion collecting sensors are used to meet the requirement for high accuracy ion balance measurement to levels of less than one volt. The voltage of the charged plate is initialized prior to discharge time testing. Balance tests, positive discharge tests, and negative discharge tests can be initialized from a remote location through digital command signals.
The charged plate voltage can be remotely monitored through a rear panel connection. The voltage output at the Output “HI” terminal in reference to the Output “LO” terminal (ground) is a proportional buffered representation of the charged plate voltage at a scale factor of 1 to 22 (other scale factors are available). The Model PD04002A wide temperature range charged plate monitor functions with standard, custom, or high temperature charged-plates. The monitor and high-temperature charged-plate can be used on a table top or securely mounted by fasteners to the bottom of the unit. CE compliant.
