Features
-
Low cost plug-compatible drop-in replacement gauge for
Convectron
®
gauges and Mini-Convectron
®
modules.
-
Performance identical to existing Convectron
®
gauges.
-
Wide Measuring Range 10
-4
Torr to 1000 torr.
-
Rugged robust design withstands more abuse and harsh
environments.
-
Significant savings for you - no changes to your system
- use your existing Convectron
®
controllers, cables, and modules.
-
No changes to your process. A single vacuum gauge can
monitor your vacuum system pumpdown and venting.
Helps keep your process up and running, even if it's not a
laboratory environment.

Gauge
The InstruTech CVG convection vacuum gauge provides
equivalent or better performance throughout the range of
10
-4
to 1000 torr.
Only the same, equivalent or better materials are used in the
vacuum environment. Clean assembly procedures assure compat-
ibility with today's contamination-sensitive processes. All tooling
that comes in contact with vacuum surfaces of the InstruTech
gauge are of very low vapor pressure materials. the internal surface
area of the gauge has been decreased by almost 75%, improving
the response time of the gauge to lower pressures. Temperature
compensation has been moved to the external environment to
improve response time to temperature changes.
Lower cost without sacrificing quality
InstruTech has incorporated numerous changes that help
reduce cost and improve performance. By moving temperature
compensation out of the vacuum environment, costs have been
significantly reduced and performance improved, over the range of
10 to 50°C.
The gauge is bakeable to 150°C and is shielded against RF
interference. A fine mesh screen in the gauge port helps prevent
particulate contamination from entering the gauge. A new attach-
ment means for the sensor is far more reproducible and easier to
make. These and other improvements add up to significant cost
savings to you.
Directly compatible with existing Convectron
®
con-
trollers, cables, and modules
The InstruTech CVG gauge will directly replace standard
Helix/GP Convectron
®
gauges. It is directly interchangeable with
your existing Convectron
®
controllers, cables, and Mini-
Convectron
®
modules, so you don't need to change any wiring,
hardware, or process recipes.

®
Gauge
The Convectron
®
gauge has been in widespread use worldwide,
largely unchanged since Granville-Phillips introduced it in 1975.
InstruTech has completely redesigned its new gauge for significantly
lower cost, without sacrificing high quality and performance.
