1.2 Equipment Grounding
1.3 Implosion / Explosion
Glass ionization gauges, if roughly handled, may implode under vacuum causing flying glass which
may injure personnel. If pressurized above atmospheric pressure, glass tubes may explode. A
substantial shield should be placed around vacuum glassware to prevent injury to personnel.
Danger of injury to personnel and damage to equipment exists on all vacuum systems that
incorporate gas sources or involve processes capable of pressurizing the system above the limits it
can safely withstand.
For example, danger of explosion in a vacuum system exists during backfilling from pressurized gas
cylinders because many vacuum devices such as ionization gauge tubes, glass windows, glass bell
jars, etc., are not designed to be pressurized.
Install suitable devices that will limit the pressure from external gas sources to the level that the
vacuum system can safely withstand. In addition, install suitable pressure relief valves or rupture
disks that will release pressure at a level considerably below that pressure which the system can
safely withstand.
Suppliers of pressure relief valves and pressure relief disks are listed in the Thomas Register under
“Valves, Relief” and “Discs, Rupture.”
Confirm that these safety devices are properly installed before installing the product. In addition,
check that:
a. The proper gas cylinders are installed,
b. Gas cylinder valve positions are correct on manual systems, and
c. The automation is correct on automated gas delivery systems.
d. Vacuum gauges with compression fittings may be forcefully ejected if the vacuum system is
pressurized.
Proper Grounding
All components of a vacuum system used with this or any similar high voltage
product must be maintained at earth ground for safe operation. The power cord of
this product shall be connected only to a properly grounded outlet. Be aware,
however, that grounding this product does not guarantee that other components of
the vacuum system are maintained at earth ground.
Complying with the usual warning to connect the power cable only to a properly
grounded outlet is necessary but not sufficient for safe operation of a vacuum system
with this or any similar high voltage producing product.
Verify that the vacuum port to which the Ionization Gauge or Convectron Gauge is
mounted is electrically grounded. It is essential for personnel safety as well as proper
operation that the envelope of the gauge be connected to a facility ground. Use a
ground lug on a flange bolt if necessary.
Install suitable devices that will limit the pressure to the level that the vacuum
system can safely withstand. In addition, install suitable pressure relief valves or
rupture disks that will release pressure at a level considerably below the pressure
that the system can safely withstand.

12 Series 330 Vacuum Gauge Controller
Instruction Manual - 330004 - Rev. 02
Series 275 Convectron gauges are furnished calibrated for N2. They also measure the pressure of air
correctly within the accuracy of the controller.
It is the installer's responsibility to ensure that the automatic signals provided by the product are
always used in a safe manner. Carefully check manual operation of the system and the set point
programming before switching to automatic operation.
Where an equipment malfunction could cause a hazardous situation, always provide for fail-safe
operation. As an example, in an automatic backfill operation where a malfunction might cause high
internal pressures, provide an appropriate pressure relief device.
Series 275 Gauges should not be used above 1000 Torr true pressure.
If accurate conversion data is not used, or is improperly used, a potential
overpressure explosion hazard can be created under certain conditions.
Do not attempt to use a Series 275 gauge calibrated for N2to measure or control the
pressure of other gases such as argon or CO2unless accurate conversion data for N2
to the other gas is properly used. See Section 5.3 on page 44.
If used improperly, Convectron gauges can supply misleading pressure indications
that can result in dangerous overpressure conditions within the system.
Do not operate in an explosive atmosphere.
Do not operate the product in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment constitutes a definite
safety hazard.
Do not use the product to measure the pressure of explosive or combustible gases or
gas mixtures. The sensor wire of the Convectron Gauge normally operates at only
125 ˚C, but it is possible that Controller malfunction can raise the sensor
temperature above the ignition temperature of combustible mixtures.
Danger of explosion or inadvertent venting to atmosphere exists on all vacuum
systems which incorporate gas sources or involve processes capable of pressurizing
the system above safe limits.
The fumes from solvents such as trichloroethylene, perchloroethylene, toluene, and
acetone can be dangerous to health if inhaled. Use only in well ventilated areas
exhausted to the outdoors. Acetone and toluene are highly flammable and should not
be used near an open flame or energized electrical equipment.

2.2 The Series 330 Vacuum Gauge Controller
The 330 Vacuum Gauge Controller (VGC) is provided with a single ionization gauge control. It can
be used to measure pressures 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 using an ionization gauge; or from 1.0 x 10-3 Torr (1.0 x 10-3 mbar or 1.0 x 10-1 pascal)
to 999 Torr using Convectron gauges, or from 1 x 10-3 Torr to 1 Torr using thermocouple gauges.
Pressure ranges are air equivalent.
Pressure readout is via a front panel digital display for the ion gauge, and analog outputs for either
the Convectron gauges or thermocouple gauges.
The 330 VGC is a modular instrument with infrequently used controls housed behind a hinged front
panel, thus reducing front panel clutter and allowing the VGC to reside in a half-rack space.
2.2.1 Degas Function
The 330 VGC has a factory installed resistance heating degas option. An interlock is provided to
only allow degas when the ion gauge tube is ON and displayed pressure is below 5 x 10-5 Torr.
Pressure reading during degas is not possible due to the I2R degas function.
2.2.2 Remote Input/Outputs
The VGC comes with a factory installed remote I/O option which provides an ionization gauge
relay status output, remote gauge on/off and remote degas on/off functions.
2.2.3 Analog Output Signals
Analog outputs for the ion gauge are provided for all controllers. Analog outputs for Convectron
gauge or thermocouple gauge options are covered in the respective chapters of this instruction
manual.

1x10
-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 N2
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.

2.5 Ionization Gauge Types and Installation
The 330 VGC operates a Bayard-Alpert type or equivalent ionization gauge. It is ideally suited for a
nude ionization gauge such as the Granville-Phillips 274022 or 274023 which have an X-ray limit
in the low 10-11 Torr range. Coated Iridium filament type gauges are recommended since at higher
pressures they provide longer operating life and greater burnout resistance.
When installing an ion gauge, note that if it is placed near the pump, the pressure in the gauge may
be considerably lower than in the rest of the system. If placed near a gas inlet or source of
contamination, the pressure in the gauge may be higher.
If an unshielded gauge is placed near an electron beam evaporation source or used in a sputtering
system, spurious electrons or ions may disturb the measurement. Screens or other shielding should
be placed between the gauge and the system if spurious charged particles or severe electromagnetic
interference is present. Consideration should also be given to electrostatic shielding of glass
tubulated gauges when measuring pressures near their x-ray limits.
Brooks Automation, Inc./Granville-Phillips offers 3 cable types for ion gauges. One has a standard
connector for the series 274 tubulated gauges; one has a standard connector for series 274 nude
gauges; and one has individual pin sockets for use with nonstandard pin configurations as well as
Granville-Phillips nude gauges.
Figure 2-3 shows typical gauge base configurations using the cables listed above and shown in
Figure 2-4, 2-5, and 2-6.
Figure 2-3 Standard Gauge Base Configuration
NOTE: To use the second filament of a dual
filament gauge, the cable connector at the
gauge is removed and rotated 180o, then
reinstalled.

2.5.1 Ion Gauge Cables
Do not attach cables to glass gauge pins while the gauge is under vacuum.
Accidental bending of the pins may cause the glass to break and implode.
Cables, once installed, should be secured to the system to provide strain relief
for gauge tube pins.
Ionization gauges are safe for use only if all exposed conductors on the gauge
and on controller and on vacuum system are grounded.
