Introduction / General Information
Description
Thermal conductivity gauges measure pressure indirectly by sensing the loss of heat from a sensor to the surrounding gases. The higher the pressure of the surrounding gas, the more heat is conducted away from the sensor. Pirani thermal conductivity gauges maintain a sensor (usually a wire) at some constant temperature and measure the current or power required to maintain that temperature. A standard Pirani gauge has a useful measuring range of about 10-4 Torr to 10 Torr. By taking advantage of convection currents that are generated above 1 Torr, convection enhanced Pirani gauges increase the measuring range to just above the atmosphere. The INFICON PGE050 Pirani Gauge Enhanced is a convection enhanced Pirani vacuum gauge sensor that interfaces with external controllers such as the INFICON VGC031 controller. The PGE050 is also a direct drop-in replacement pin-pin compatible gauge for the MKS Instruments / Granville-Phillips® 275 Convection ® gauge. The sensor connector has the same pinouts and signal as the corresponding Convectron®. It is directly interchangeable with your existing Convectron® controllers and cables, so you don’t need to change any wiring, hardware, or process recipes.

Safety Precautions – General
WARNING! There are no operator-serviceable parts or adjustments inside the gauge sensor. Do not modify this product or substitute any parts without au- authorization of qualified INFICON service-trained personnel. Return the product to an INFICON-qualified service and repair center to ensure that all safety features are maintained. Do not use this product if unauthorized modifications have been made.
Electrical Conditions
\ WARNING! When high voltage is present in any vacuum system, a life-
threatening electrical shock hazard may exist un- less all exposed electrical
conductors are maintained at earth-ground potential. This applies to all
products that come in contact with the gas contained in vacuum chambers. An
electrical discharge within a gaseous environment may couple dangerous high
voltage directly to any ungrounded conductor of electricity. A person could be
seriously injured or killed by coming in contact with an exposed, ungrounded
electrical conductor at high voltage potential. This condition applies to all
products that may come in contact with the gas inside the vacuum chamber
(vacuum/pressure containment vessel).
Proper Equipment Grounding
WARNING! Hazardous voltages that could seriously injure or cause death
are present in many vacuum processes. Verify that the vacuum port on which the
PGE050 vacuum gauge module is mounted is electrically grounded. Consult a
qualified Electrician if you are in doubt about your equipment grounding.
Proper grounding of your equipment is essential for safety as well as the
intended operation of the equipment. The PGE050 mo- dule vacuum gauge must be
connected directly to a good quality earth ground. Use a ground lug on the
PGE050 gauge vacuum connection/flange if necessary
WARNING! In order to protect personnel from electric shock and bodily harm, shield all conductors that are subject to potential high voltage electrical discharges in or around the vacuum system.
Electrical Interface and Control
It is the user’s responsibility to ensure that the electrical signals from
this product and any connections made to external devices, for example, relays
and solenoids, are used in a safe manner. Always double-check the system setup
before using any signals to automate your process. Perform a hazardous
operation analysis of your system design and ensure safeguards and personnel
safety measures are taken to prevent injury and property damage.
Overpressure and use with hazardous gases
A WARNING Install suitable protective devices that will limit the level of
pressure inside your vacuum chamber to less than what the vacuum chamber
system components are capable of withstanding. INFICON gauges should not be
used at pressures exceeding 1000 Torr absolute pressure.
In cases where an equipment failure could cause a hazardous condition, always
implement fail-safe system operation. For example, use a pressure relief
device in an automatic backfill operation where a malfunction could result in
high internal pressures if the pressure relief device was not installed on the
chamber.
The PGE050 vacuum gauge module is not intended for use at pressures above 20
psi (1000 Torr); DO NOT exceed 35 psi (<2½ bars) pressure inside the sensor.
If your chamber goes to higher pressures, you should install an isolation
valve or pressure relief device to protect the gauge tube from overpressure
conditions. With some fittings, actual safe overpressure conditions may be
lower; for example, a quick-connect, O-ring compression fitting may forcibly
release the gauge tube from the vacuum chamber fitting with only a few psi
over local uncover-reacted barometric (atmospheric) pressure.
CAUTION! If the internal pressure of a vacuum gauge device is allowed to increase above local uncorrected barometric pressure (atmospheric pressure side), vacuum fit- tings may release and possible overpressure conditions may cause leaks that would allow the gas inside the gauge tube to release into the atmosphere of the surrounding environment. Toxic, pyrophoric, and flammable gases are amples of hazardous gases that if allowed to leak out of the vacuum/pressure containment vessel into the atmospheric environment, could cause bodily injury and possible dam- age to equipment. Never expose the gauge tube internal volume to pressure above local atmospheric pressure when using hazardous gases.
Gases other than Nitrogen/air
WARNING! Do not attempt to use gases other than nitrogen (N2) or air
without referring to correction factor data tables.
INFICON gauges are calibrated for direct readout of nitrogen or air. Do not
attempt to use other gases such as argon (Ar) or carbon dioxide (CO2) unless
accurate conversion data for N2 to other gases is properly used. Refer to the
correction factor data listed in the controller Operating Manual operating
this device. The INFICON VGC031 controller Operating Manuals provide a more
complete discussion of using correction factors when using the gauge on gases
other than Nitrogen.
WARNING! Do not use this device in an explosive atmosphere or in the presence of flammable gases, vapors or fumes. Do not use this device to measure the pressure of explosive or combustible gases or gas mixtures. The sensor wire in the gauge normally operates at 125 °C, but if a malfunction should occur, the wire temperature could exceed the ignition temperature of certain combustible gases and gas mixture. This could cause an explosion which could result in serious injury or death.
Installation
Mechanical Installation
Mount the PGE050 as close as possible to the pressure you want to measure.
Long or restricted, small-diameter tubing will create a pressure difference
between your process chamber and the gauge. This may cause a delay in response
to pressure changes.
Mounting the PGE050 too close to a gas source inlet may also cause measurement
and control instability. Do not mount the PGE050 near a source of heating or
cooling, such as heaters or air conditioning vents.
Mount the PGE050 with its main (long) axis horizontal (see diagram below).
Pressure reading errors may occur above 1 Torr if the unit is not mounted
horizontally. Below 1 Torr, the mounting position has little to no effect.
For accurate measurements above 1 Torr, mount the gauge axis horizontally as
shown below:
Mount the PGE050 with port down, if possible, to help minimize the effect of any particles or condensation from collecting in the gauge.
Do not mount the PGE050 where it will be subjected to excessive vibration. Vibrations may cause unstable readings, measurement errors and possible mechanical stress to components in the PGE050. Flanges/ Fittings – follow the manufacturer’s recommendations and note the following: – NPT fittings: When connecting the device using an NPT fitting, apply a thread sealant compound or wrap the threaded portion of the tubing with one-and-a-half to two wraps of pipe thread seal tape such as PTFE (Teflon®) tape and hand tighten the gauge into the gauge port. Do not use a wrench or other tool which may damage the gauge.
Electrical Installation
Grounding
- Be sure the vacuum gauge and the rest of your vacuum system are properly grounded for safety as well as intended operation of the equipment. When using KF flanges, metal clamps must be used to ensure proper grounding. Be aware that some vacuum fittings such as NPT connections installed using Teflon tape may not allow for metal-to-metal contact between the vacuum gauge and the vacuum chamber. If such is the case, use a 12 gauge or larger copper wire to connect the vacuum gauge to a ground lug on your vacuum chamber as shown below.
Using the gauge with different gases
A thermal conductivity gauge senses heat loss which depends on the thermal conductivity of the gas surrounding the sensor. Since different gases and mixtures, have different thermal conductivities, the indicated pressure readings and outputs will also be different. INFICON convection gauges (and most other ther- mal conductivity gauges) are calibrated using nitrogen (N2). When a gas other than N/ air is used, correction must be made for the difference in thermal conductivity between nitrogen (Nz) and the gas in use. The gas correction data, charts, and tables listed in vour controller (such as the INFICON VGC031 control- ler) Operating Manual indicate how different gases affect the display and output from an INFICON convection gauge.
WARNING! Using a thermal conductivity gauge with gases other than that
for which it is calibrated could result in death or serious injury. Be sure to
use the correction factor data listed in the controller Operating Manual
operating this device. For N the calibration shows excellent agreement between
indicated and true pressure throughout the range from 1×10* to 1000 Torr. At
pressures below 1 Torr, the calibration curves for the different gases are
similar. The difference in readings at these low pressures is a constant, a
function of the difference between the thermal conductivities of the gases.
At pressures above 1 Torr, indicated pressure readings may diverge
significantly. At these higher pressures, convection currents in the gauge
become the predominant cause of heat loss from the sensor and calibration
depends on gauge tube geometry and mounting position as well as gas
properties. Generally, air and N2 are considered the same with respect to
thermal conductivity, but even Nz and air will exhibit slight differences in
readings at higher pressures. For example, when venting a system to the
atmosphere using N2, you may see readings change by 40 to 55 Torr after the
chamber is opened and air gradually displaces the Nz in the gauge. For most
other gases the effect is much more significant and may result in a hazardous
condition as described below.
Other considerations when using gases other than Nz / air
Flammable or explosive gases
WARNING! INFICON convection gauges are neither intrinsically safe nor
explosion-proof and are not intended for use in the presence of flammable or
explosive gases or vapors. Under normal conditions, the voltages and currents
in INFICON convection gauges are too low to cause ignition of flammable gases.
However, under certain failure conditions, sufficient energy could be
generated to cause flammable vapors or gases to ignite or explode. Thermal
conductivity gauges like the INFICON convection gauges are not recommended for
use with flammable or explosive gases.
Moisture/water vapor
In some processes (lyophilization, for example) the gas composition may not
change significantly, except for moisture content. Water vapor can
significantly change the response of a thermal gauge and correction should be
made, as you would for any other gas.
Other contaminants
If your gases condense, coat, or corrode the sensor, the gauge calibration and
response to different gases will change. Generally, if the gauge can be
“calibrated” (“zero” and “span” settings) these changes are small enough to be
ignored. If you can’t set zero and span, the gauge should be replaced or
returned to the factory for evaluation and possible cleaning.
Convection Vacuum Gauge
Indicated vs. true total pressure (test gaseous N2, Ar, He)
Gas Correction Chart
The Y-axis of the above chart is actual pressure as measured by a capacitance
manometer, a diaphragm gauge that measures true total pressure independent of
gas composition. The X-axis is the pressure reading indicated by the
convection gauge under test. This chart shows readings for an INFICON
convection gauge (CVG) and Granville-Phillips® Convectron® gauge to illustrate
that the difference in the response for both of these types of gauges is
virtually indistinguishable.
CAUTION! Do not assume this data applies to other convection gauges which
may or may not be the same. Refer to the correc- tion factor data listed in
the controller Operating Manual operating this device. The INFICON VGC031
controller Operating Manuals provide a more complete discussion of using
correction factors when using the gauge on gases other than Nitrogen. Ex A: If
the gas is nitrogen (N2), when the true total pressure is 500 Torr, the gauge
will read 500 Torr.
Ex B: If the gas is argon (Ar), when the true pressure is 100 Torr, the gauge will read about 9 Torr. If you are backfilling your vacuum system with Ar, when your system reaches a pressure of 760 Torr true pressure your gauge will be reading about 23 Torr. Continuing to backfill your system, attempting to increase the reading up to 760 Torr, you will over-pressurize your chamber which may present a hazard. Ex C: If the gas is helium (He), the controller will read over pressure (OP) when the pressure reaches about 10 Torr true pressure and opening the chamber to the atmosphere prematurely may present other hazards for both people and product.
CAUTION! What these examples illustrate is that using gases other than
nitrogen (N2) without using accurate gas conversion data and other proper
precautions could result in injury to personnel and/or damage to equipment.
Suggested precautions when using gases other than nitrogen (N2):
Install a pressure relief valve or burst disk on your chamber, to protect it
from overpressure. Post a warning label on your gauge readout that states “Do
Not Exceed Torr Indicated Pressure” (fill in the blank for the maximum
indicated pressure for the gas you use) so that an operator using the gauge
will not exceed a safe pressure.
Service
Calibration
Every INFICON PGE050 gauge is calibrated prior to shipment using nitrogen
(N2). However, you can calibrate the instrument by adjusting zero and span
(atmosphere), using the controller which is operating the gauge. Zero and span
(atmosphere) calibration affects the displayed value and the output signal.
Zero calibration optimizes performance- 1.00×10 To 1 1.010 For in gor minimum
operating pressure is higher than 1.00×10 Torr, it is not normally necessary
to perform calibration at zero and thus span calibration should be adequate.
If you are able to evacuate your system to below 1.00×10* Torr, it is always a
good practice to check and set zero if necessary. This will also improve
performance in cases where gauge contamination is causing higher readings than
below 1. 710 Ton. Cares tout exercised when using to gases other than nitrogen
(N2) / air.
Maintenance
In general, maintenance is not required for your INFICON gauge. Periodic
performance checks may be done by comparing the gauge to a known reference
standard.

Contamination
The most common cause of all vacuum gauge failures is contamination of the sensor. Noisy or erratic readings, the inability to set zero or atmosphere, and total gauge failure, are all possible indications of gauge contamination.
Contamination can be generally characterized as either:
- a reaction of process gases with sensor elements, or
- an accumulation of material on the sensor elements. Sensors that fail due to chemical reactions are generally not salvageable. Sensors that fail due to condensation, coatings, or particles may possibly be restored by cleaning.
Reactive Gases
If process gases react with the materials of construction of the sensor, the
result is corrosion and disintegration of the sensor over time. The chemistry
of the gases used for plasma etching and other reactive semiconductor
processes are examples of where this failure mode is possible. In this case,
cleaning can’t solve the problem because the sensor has been destroyed. The
sensor or module must be replaced. If you experience this failure mode quickly
or frequently, you should consider a different vacuum gauge for your
application. Thermal vacuum gauges may be available with different sensor
materials that are not as reactive with your particular process gases. The
standard gold-plated tungsten sensor used in the INFICON convection gauge is
offered for use with air and inert gases such as N2, argon, etc. INFICON also
offers modules with platinum sensors for applications not compatible with
gold-plated tungsten.
There is no material that is universally chemical resistant; your choice of
vacuum gauge (as well as all other vacuum components) should take into
consideration the potential reactions between your process gases and the
materials of construction. Consider what effect water vapor will have when
combined with your process gases because a finite amount of water will enter
the chamber during venting to the atmosphere with air.
Oil, Condensation, Coatings, and Particles If the failure is due to an
accumulation of material in the gauge, we may be able to restore your gauge or
module by cleaning. Contamination may be as simple as condensed water, or as
difficult as solid particles. Oils and hydrocarbons: Exposure of the gauge
internal surfaces to oils and hydrocarbons can result in sensor contamination.
Some of these types of contamination may be removed by cleaning the gauge. If
there is the possibility of oil back streaming from wet vacuum pumps, it is
recommended that a filter or trap be installed to prevent contamination of
components of your vacuum system.
Condensation: Some gases (such as water vapor) can condense on sensor
surfaces, forming a liquid coating that changes the rate at which heat is
removed from the sensor (which changes the calibration). The sensor can often
be restored simply by pumping on the gauge between process cycles. A dry Nz
purge will help speed up drying, or the gauge may be gently heated provided
the temperature doesn’t exceed the specified limit of 40 °C, operating.
Coatings: Some gases can condense on sensor surfaces, forming a solid coating,
which changes the rate at which heat is removed from the sensor. Some of these
coatings may be removed by cleaning the gauge.
Particles: Particles generated by the process may enter the gauge during the process cycle or during the venting cycle. The result is interference with heat removal from the sensor. In this case, cleaning may be able to remove particles from the gauge. However, particulate contamination is the most difficult to remove as particles can become stubbornly trapped inside the gauge. In some processes, solid particles are created during the process throughout the chamber including inside the gauge. Par- ticles tend to form on cooler surfaces such as in a gauge at room temperature. You may slow down the build-up of particles in the gauge by keeping the gauge warm (within specified limits) during the process cycle.
Particles in the process chamber may be swept into the gauge during the vent cycle. The PGE050 has a screen built into the gauge port to help keep the largest particles out of the gauge. In very dirty applications, or where particles are small enough to get through the screen, an additional filter installed on the inlet may help prolong the gauge life. In some vacuum processes, desorbed and sputtered materials from the process may enter vacuum components connected to the process vacuum chamber by line-of-sight transport, especially under high vacuum conditions, i.e., in the molecular flow regime. To prevent materials that may be transported via line-of- sight momentum from entering your vacuum gauge or other components, it is advisable to install some form of apparatus that will block the line-of-sight. In many cases a simple 90° elbow may help prevent or reduce the transport of particles from entering your vacuum gauge. In the event of gauge contamination please contact the factory to return the gauge for possible cleaning if the gauge has not been exposed to hazardous materials.
Gauge Replacement
If the PGE050 gauge fails for any reason, and cleaning does not resolve the
issue, the PGE050 gauge should be replaced.
