Pressure Control For
Vacuum
Apex Vacuum Pressure
Controllers for vacuum processed, provide pinpoint control
for vacuum ranges from
0.1 torr
to 760 torr(1 atm). With
update times of 100 milliseconds, the Apex Vacuum Pressure
Controller responds quickly to provide smooth pressure steps
needed in critical processes.
The Apex Vacuum Pressure Controllers
can be used in conjunction with the Apex Mass Flow
Controllers and Meters. Communication input/output can be
user specified with the choices being 0-5V, 0-10V, or
RS-232(provided on all Pressure Controllers). No control box
is needed for providing power to the unit, just the PVPS24U
Universal Power Supply. The on-board display buttons can
also be used to set the control pressures.
The 4 torr to 760 torr version uses an
on-board sensor, while the Apex VPC uses a capacitance
diaphragm gauge on the vacuum system to sense pressure. The
Apex APC can be used with many CDG's. Standard models use a
10 torr, 20 torr, 100 torr, 200 torr, or 1000 torr model CDG.
The Apex Vacuum Pressure Controller has
a user display to change gases, set the pressure and display
readings. The RS 232 interface allows control of 26
individual controllers or meters off one computer RS 232
port.
