Series 979 ATV Transducer 15
The 979 ATV Transducer is designed to measure vacuum chamber pressures
as part of a user’s designed system processes. It combines a Hot Cathode
sensor to measure pressures from 5x10
-10
to 3x10
-3
Torr and a MicroPirani
sensor to measure pressures from 1x10
-3
to atmosphere. Once integrated into
the vacuum system, the 979 ATV Transducer’s functions are computer-
controlled, requiring little manual intervention by the user. This enables the
system to monitor pressure as a procedure invisible to the user, and when the
desired pressure
is reached, trigger
the next event in
the system
process.
This manual
describes the
installation and
configuration
tasks necessary
to set up the 979
ATV Transducer.
After the device is
set up, a software
engineer at the
user’s installation
would use the
communications
protocol described
in this manual to
create a software
program (in, for
example, Visual
Basic, C, or C++)
that will
automatically
control 979
operation.
