Vacuum Gauge Controller

G

ranville-Phillips 340 Vacuum Gauge Controller (VGC)

measures pressure from less than 1 x 10

-9

Torr to

atmosphere, utilizing an ionization gauge and two

Convectron gauges. Pressure from each gauge is indicated inde-

pendently on three front panel digital displays and by rear panel

analog outputs.

Resistance heating degas of the ionization gauge

is standard.

Infrequently used controls are housed behind a hinged front

panel to reduce front panel clutter. The 3 1/2" high controller is

available as a compact 8" wide bench mount unit.

Excellent efficiency of the integral power supply and low

internal power consumption allows the 340 to run cool without

requiring ventilation openings in its aluminum enclosure. This helps

avoid failures that can be induced by heat or foreign materials.

Improved Long-Term Accuracy

L

ong-term accuracy of pressure measurement is

essential in vacuum processing to achieve maximum

throughput. Conventional IG Systems will typically

provide pressure indications that are uncertain by 30 to 40% at

mid-range and by several hundred percent at higher pressures

when new. Even accurate calibration does nothing to improve the

accuracy of readout on non STABIL-ION Systems. With these

older systems, you must use lookup tables to get accurate

information and, with use, the calibration typically changes

resulting in unavoidable errors. Only STABIL-ION Systems can

automatically correct for the inherent nonlinearity in sensitivity in

all Bayard-Alpert type gauges. Compare the 2, 3, or 6%

uncertainty of readout at mid-range of STABIL-ION Systems

(depending on the system ordered) with the approximately 10

times larger uncertainty of

older systems and you will choose

STABIL-ION Systems.

Reliability is Designed In

With STABIL-ION Gauges, there is no glass breakage, glass

decomposition, or helium permeation. Conventional nude

ionization gauges also have no glass envelopes; however, the lack

of a fixed metal envelope and shields around the electrodes

means that any change on the position or potential of any surface

in the vicinity of the nude gauge affects its accuracy.

GPC uses a proprietary filament coating process with greatly

improved adhesion and uniformity of coating for longer cathode

life. A number of pre-production STABIL-ION Gauges have been

operating continuously for over 42 months.
