Overview |1-1
OVERVIEW
Follow these safety precautions when working on the sensor:
Disconnect AC power from the analyzer before performing any main-
tenance or troubleshooting.
The furnace and furnace insulation cover are hot during normal oper-
ation (up to 500°F/260°C inside the furnace insulation cover). Allow
analyzer components to cool for at least an hour before working inside
the analyzer. Use caution and wear appropriate gloves when handling
components or when touching analyzer components near the furnace!
Basic Elements of the Sensor
The CG1000 analyzer consists of the following basic systems:
• The Plumbing: All inlet and outlet tubing (cell housing). Also includes
the calibration gas inlet and aspirator assembly, with the aspirator
used to pull the sample into the sensor.
• The Measuring System: Zirconium oxide cell.
• The Temperature System: The electrical cell heater (furnace), sensor
case heaters, the type “K” thermocouple (maintains cell operating
temperature), and the sensor board containing cold junction compen-
sation. The sensing cell operates at a constant temperature. The circuit
board in the sensor terminal box switches power to the furnace from
the AC mains connected to the sensor. This board also provides cold
junction compensation to the thermocouple circuit.

1-2 | Thermox CG1000 Oxygen Analyzer
The Oxygen Measuring Cell
The sensing element itself is a closed-end tube or disk made from ceramic
zirconium oxide stabilized with an oxide of yttrium or calcium. Porous
platinum coatings on the inside and outside serve as a catalyst and as
electrodes. At high temperatures (generally above 1200°F/650°C), oxygen
molecules coming in contact with the platinum electrodes near the sensor
become ionic. As long as the oxygen partial pressures on either side of the
cell are equal, the movement is random and no net flow of ions occurs.
If, however, gases having different oxygen partial pressures are on either
side of the cell, a potentiometric voltage is produced (See Figure 1-1). The
magnitude of this voltage is a function of the ratio of the two oxygen par-
tial pressures. If the oxygen partial pressure of one gas is known, the volt-
age produced by the cell indicates the oxygen content of the other gas. A
reference gas, usually air (20.9% O2), is used for one of the gases.
Since the voltage of the cell is temperature dependent, the cell is main-
tained at a constant temperature. Some newer high temperature insitu
models use the heat from the process to heat the sensor, and the process
temperature is continuously measured and used in the software calcula-
tion. The oxygen content is then determined from the Nernst equation:
E = In
RT
4F
O1
O2
where R and F are constants, T is absolute temperature, and O1and O2
are the oxygen partial pressures on either side of the cell.
Figure 1-1.
Zirconium oxide cell principle of operation.

Overview |1-3
For measuring oxygen in non-combustibles gases, the calibration of an
analyzer is obtained from the formula:
AT = 48.0 at 695°C
E = A*T*Log 20.9%
O2Unk% AT = 54.4 at 824°C
Where Ais a constant, Tis the cell temperature on an absolute scale (°C +
273) and O2 Unk% is the unknown oxygen concentration of the gas to be
analyzed, and which is calculated by the analyzer.
Because of the high operating temperature of the cell, combustible
gases that are present may burn. When this occurs, the cell will gener-
ate a higher than expected millivolts and cause the display to indicate
less oxygen than is actually in the gas.
Hydrocarbons
When hydrocarbons are present in the gas sample, a combustion process
occurs when this gas sample is exposed to the high temperature of the
zirconia cell. An indication that hydrocarbons may be present in the gas
sample is that the oxygen reading will be lower than expected. For ex-
ample, if a calibration gas cylinder has an oxygen value of 20 ppm and 5
ppm of hydrogen (balance nitrogen), the oxygen analyzer will read 17.5
ppm of oxygen. The reduction of oxygen is due to the combustion process
where 5 ppm of hydrogen will combine with 2.5 ppm of oxygen to form
water. Thus, the oxygen analyzer will read 17.5 ppm rather than the actual
20 ppm oxygen. Note that the amount of oxygen reduction is dependent
on the type of hydrocarbons present in the sample gas.
NOTE


1-4 | Thermox CG1000 Oxygen Analyzer
Proper Sensor Operations
Follow these general guidelines when using the CG1000 analyzer:
• Do not use pipe dope on any joints of the sample tubing, or any other
contaminant that gives off combustible vapor which can cause errone-
ous measurements.
• Do not use calibration gases if they contain a mixture of oxygen and
combustibles.
• Always introduce calibration gases at the recommended flow rate.
Also, be sure that calibration and sample gases are introduced into the
analyzer at the same flow rate.
• When working on the plumbing inside the analyzer, turn the power
off. The heater has exposed windings and a short to the plumbing will
blow the fuse and could damage the furnace or thermocouple.
• Donothandlethecellexcessively.Donottrytocleanthecellexcept
by rinsing.
• Donotremoveacellortype“K”thermocouplethatyoumaywantto
use again when the inside of the furnace is still hot - severe thermal
shock can be destructive to either of them.
• Calibratetheflowsensorusingnitrogenasyourcarriergas.
• Donotpressurizetheexternalflowmeterwhencalibratingtheinter-
nal flow sensor.
• Waitonehourbetweenperformingathermalandregularcalibration.
• Allowcalibrationgasestostabilizebeforeproceedingtothenextstep

• Donotovertightencompressionfittingswhenservicingtheanalyzer.

INSTALLATION
This chapter shows you how to install your CG1000 oxygen analyzer. It
includes the following:
Inspect Shipping Contents
Mechanical Installation
Wiring
No operator serviceable components are inside the CG1000. Never
open the analyzer cover. Refer servicing to qualified personnel.
Inspect Shipping Contents
Remove any packing material from the CG1000 analyzer. Check for dam-
age. If any damage is found, notify the shipper.

3-2 | Thermox CG1000 Oxygen Analyzer
Mechanical Installation
This section describes how to perform the mechanical installation portion
of your system installation.
The CG1000 should be located as close to the sampling system as possible.
The ambient temperature where the analyzer is used must be in the range
of 5oC to 40oC (41oF to 104oF). If using the optional built-in pump, the ambi-
ent temperature range is -10°C to 40°C (14°F to 104°F).
Figure 3-1. Rear of CG1000 analyzer.
Sample Gas Requirements/Connection
Figure 3-1 shows the inlet and outlet ports on the CG1000. The sample gas
should be clean and dry. If the sample contains any condensing moisture,
the entire sample line should be heat traced. If the sample contains par-
ticulates greater than 15 microns, install a filter on the sample gas inlet.
Maximum sample temperature is 70°C (160°F).
Combustibles in the sample can burn with available oxygen to pro-
vide lower-than-expected oxygen levels. be aware of this, especially if
measuring oxygen in the low ppm ranges.
