MULTI-CHANNEL ZIRCONIA OXYGEN ANALYZER
DATA SHEET
This oxygen analyzer measures at multiple points the
oxygen concentration included in the exhaust gas from a large
boiler, and simultaneously outputs the average value of the
concentrations.
Since the distribution of oxygen concentration in exhaust
gas is not uniform with a large boiler such as found in a power
plant, the concentration is measured at multiple points in a
flue. These values are averaged to provide an optimum
oxygen concentration signal which is necessary for
combustion control.
The converter (ZRN) will accept inputs from up to nine
direct-insertion type zirconia oxygen detectors (ZFK), and
carries out computations such as averaging of signals from
the detectors.
The detectors are available in general-use, anticorrosive
and high-temperature types for selection according to the
customer's intended use.

General-use detector
High-temperature detector
FEATURES
1. Up to nine detectors connectable
3, 6 or 9-channel configuration is selectable, and channels
are freely usable within the selected number. Addition of
channel unit allows expansion in units of 3 channels (9
channels max.).
2. Interactive setting of parameters
Various parameters for measurement and maintenance
are easily settable through interaction with the liquid
crystal display.
3. A variety of output signals
Available as analog output are 3 sets of average-value
outputs (average values from desired channel combination) and oxygen concentration output for each channel.
Also there are 4 contact outputs per channel and 7 contact
outputs common to all channels. All of the analog outputs
are isolated.
4. Full complement of maintenance functions
Auto calibration function and manual/auto blow-down
function are standard-equipped. A self-diagnosis function
for the main unit facilitates taking a remedy at the
occurrence of a fault.
5. Sampling device is unnecessary
Gas sampling devices such as gas aspirator and
dehumidifier are unnecessary since the detector is a
direct-insertion type. The detector is available in a hightemperature type for measurement of hot gases up to
1590°C and an anticorrosive type for measurement of
strongly corrosive gas from a garbage incinerator.

CAUTIONS
• If combustible gas (CO, H2 etc.) exists in the measured
gas, error will occur due to burning at the sensor section.
The inclusion of corrosive gas (Si vapor, alkaline metal, P,
Pb etc.) will shorten the life of the sensor.
• When the measured gas temperature is high (300°C or
higher), the flange should be separated from the furnace
wall in order to bring the detector flange surface
temperature below the specified value(125°C). The flow
guide should be attached in the direction in which the gas
flow to the detector decreases.
•
•
When much dust is included in the gas, the flow guide
tube should be attached at an inclination so that the flow
goes from above to below. And the flow guide should be
attached in the direction in which the gas flow to the
detector decreases.
In the case of a refuse incinerator, automatic blowback of
the flow guide should not be performed (to prevent
corrosion of the flow guide tube due to drainage). Blowdown should be performed manually when change in the
indication has become very little with the furnace
stopped.
