Versatile Microprocessor-based Charged Plate Monitor for Monitoring the Performance of Air Ionizers

Advanced Energy’s Trek PD04002A is a versatile, microprocessor-based charged plate monitor ideally suited to monitor the performance of air ionizers that are used in critical wide temperature operations.

Overview

The ultra-sensitive Trek® PD04002A makes it 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 before 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 Trek PD04002A utilizes a new technique that 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.

Benefits

• Remotely monitor the charged plate voltage using a rear panel connection
• Use on a tabletop or securely mount the monitor and charge plate with fasteners at the bottom of the unit
