Series 330 Vacuum Gauge Controller
Instruction Manual - 330004 - Rev. 02
2.3 Available Options
2.3.1 Mounting Options
The VGC can be ordered with a variety of mounting options to fit your needs. This includes half
rack (standard), bench, full rack, or two units in a full rack. See Figure 2-2.
2.3.2 Ion Gauge Electrometer Module
The Ion Gauge (IG) Electrometer Module provides ion gauge pressure readout from less than
1 x 10
-10
Torr (1.3 x 10
-10
mbar or 1.3 x 10
-8
pascal) to 1 x 10
-1
Torr, air equivalent, depending on
the gauge and emission current used. See Chapter 4.
2.3.3 Convectron Gauge Module (330026 or 330032)
The Convectron Gauge Module provides pressure measurement from 1 x 10
-4
to 999 Torr of N
2
from two Convectron Gauges simultaneously. The pressure readout is an analog output signal. See
Chapter 5.
2.3.4 Thermocouple Gauge (TC) Module (330026)
The Thermocouple Module provides the same functions as the Convectron Module, but pressure
measurement range is 1 x 10
-3
Torr to 1 Torr. See Chapter 6.
2.3.5 Process Control Module (330505)
The Process Control Module provides two single pole, double throw relays: Two channels are
associated with the ionization gauge display line. Digital setpoints have switch-setable polarity for
relay activation above or below the setpoint, or if purchased, user selectable gauge setting. Manual
override switches are built-in. See Chapter 7.
2.3.6 Ion Gauge Cables
The VGC is capable of operating an ion gauge located up to 50 feet away from the controller by
using standard cables. Cables are available for use with glass Bayard-Alpert gauges, and nude
Bayard-Alpert gauges. See Section 2.5.
