CHARGED-PLATE MONITOR
Model PD04002A
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¡Æ to 160¡Æ 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.
