Overview |1-1
OVERVIEW
Designed for applications with high particulate levels in the gas stream,
the sensor mounts directly on the combustion process to provide continu-
ous measurement of oxygen (HPII), or oxygen and combustibles (HPIIC).
Since the sample inlet and return are inside the filter and at the same abso-
lute pressure as the process, there is no flow through the filter. The sample
in the filter flows through the sensor plumbing because of a convective
motive force. The sample in the vertical cell housing is heated to 695oC,
while the sample in the return vertical tube is at about 250oC. The tempera-
ture difference generates a density difference, which circulates the gas
through the system. Process gas enters and replenishes the gas inside the
filter by diffusion only. Thus the filter never blocks, making it ideal for
high particulate applications.
Follow these precautions when working on the sensor:
Remove AC power from the sensor and allow it to cool for at least
one hour before performing any maintenance or troubleshooting
activities.
The outside of the sensor cover and all sensor assembly components
are hot during normal operation (up to 500oF inside the furnace,
260oC inside the cover). Allow sensor components to cool for at
least an hour before working inside the sensor. Use caution and
wear appropriate gloves when handling components or when
touching the sensor cover!

Basic Elements of the Sensor
The WDG-HPII analyzer consists of the following basic systems:
•The Plumbing
All inlet and outlet tubing (cell housing), the sensing cell, the sensing
cell fitting, and the combustibles flow block and detector (for com-
bustibles).
•The Measuring System
The sensing cell, combustibles detector, interconnecting wiring, and
the control unit.
•The Temperature System
The electrical cell heater (furnace), sensor case heaters with adjust-
able thermostat, the type "K" thermocouple (maintains cell operating
temperature), and the sensor board containing cold junction com-
pensation. The sensing cell operates at a constant temperature. The
circuit board in the sensor terminal box switches power to the fur-
nace from the AC mains connected to the sensor. This board also
provides cold junction compensation to the thermocouple circuit.
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 elec-
trodes. At high temperatures (generally above 1200°F/650°C), oxygen mol-
ecules coming in contact with the platinum electrodes near the sensor be-
come 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 mag-
nitude of this voltage is a function of the ratio of the two oxygen partial
pressures. If the oxygen partial pressure of one gas is known, the voltage
produced by the cell indicates the oxygen content of the other gas. A refer-
ence 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 = RT

where R and F are constants, T is absolute temperature, and O1and O2are
the oxygen partial pressures on either side of the cell.
For measuring oxygen in non-combustibles gases, the calibration of an ana-
lyzer is obtained from the formula:
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.
The cell produces zero voltage when the same amount of oxygen is on
both sides, and the voltage increases as the oxygen concentration of the
sample decreases. The voltage created by the difference in the sample gas
and the reference air is carried by a cable to the microprocessor control
unit, where it is linearized to an output signal.
Because of the high operating temperature of the cell, combustible
gases that are present may burn. When this occurs, the cell will gen-
erate high millivolts and cause the display to indicate less oxygen
than is actually in the gas (net oxygen content).

The Combustibles Detector
The Combustibles Detector is a dual element device; the elements differ
only in that one is coated with a catalyst. The catalyst causes oxidation to
occur at a lower than normal temperature. The temperature of the cata-
lyzed element changes as the combustible mixture burns. The temperature
change causes the resistance of the catalyzed element to change. The resis-
tance change is interpreted by the microprocessor and the corresponding
combustibles reading is displayed.
The Thermox catalytic combustibles detector will detect combustible gas
present in a sample. The sample must, however, contain enough oxygen to
fully burn the combustible present. The combustibles detector responds to
all unburned combustibles gases, such as CO and H2. We recommend us-
ing an even mixture of CO and H2as the combustibles component within
your span gas, although you can also use all CO if needed.

Overview |1-5
Common Operator Errors
These are some common errors to avoid; if they are avoided, your analyzer
will operate with a minimum of maintenance and troubleshooting.
•If your process is running and the analyzer is installed on the process,
the analyzer must have power applied to it to prevent plugged plumb-
ing and sensor component damage. The case heaters must be on if the
process is running to maintain sensor plumbing above the process gas
dewpoint.
•Do not use pipe dope or any other contaminant that gives off combus-
tible vapor on any joints of the sample tubing.
•For O2calibration gases, do not use calibration gases if they contain a
mixture of oxygen and combustibles. Note, however, that this is ac-
ceptable for combustibles span gases (used only if you purchased the
combustibles option).
•Always introduce calibration gases at the recommended flow rate.
•When working on the plumbing inside the sensor cabinet, turn the
power off - the oxygen cell heater has exposed windings and a short to
the plumbing will blow the fuse and could damage the furnace or ther-
mocouple.
•Do not handle the cell excessively. Do not try to clean the cell except by
rinsing. If you need to handle the cell, grasp by touching the seal fit-
ting at the top; never touch the bare part of the cell.
•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.
•Always replace the metal cell O-ring when replacing the oxygen cell.

Start Up Checklist
•Review the installation chapter before installing this system.
•Install the probe tubes (sample and exhaust) and filter assembly to the
rear of the sensor.
•Install the sensor on the process. The ambient temperature must not
exceed 70°C (160°F). If it does, the sensor board that is located in the
sensor terminal box must be relocated to a junction box not more than
25 feet from the sensor, but in a location not to exceed 70°C.
• If the sensor is on a pipe nipple, insulate the exposed portion of
the pipe (insulate from the process wall to the mounting flange
of the sensor).
•Install the control unit. The ambient temperature must not exceed
50°C. (120°F).
• Do not create any additional conduit entries in the control unit
enclosure.
•Interconnect the control unit and the sensor as described in the appro-
priate interconnecting drawing.
• The specified cable must be used to ensure the proper opera-
tion of the system.
• Keep the interconnecting located in the control unit as short as
possible. A service loop need not be used.
• Maintain the ordered wire pairs per the drawing.
• Terminate the shields or drains of the cable properly.
•Connect AC power to the control unit and the sensor. Make sure that
the AC voltage is within specified limits.
