IN-SITU
ZIRCONIA OXYGEN ANALYZER
DATA SHEET
This oxygen analyzer is used to continuously measure
oxygen concentration in combustion exhaust gas of industrial
boilers or furnaces, and is ideally suited for combustion management and control.
The analyzer system is comprised of the detector and converter coupled together as a complete system. Detector setting configuration includes the detector flow guide tube and
detector sensor. The flow guide tube is inserted directly into
the gas and directs gas to the sensor for measurement. The
converter (ZKM) is comprised of the signal processor, input/
output and communications, display and system controls.
The converter is equipped with advanced functionality
such as performing the sensor diagnostics and sensor recovery function, so the detector can be used within long term
stability.

FEATURES
1. Gas sampling device is unnecessary
For quick response, insert the detector directly into the
flue Gas sampling functions such as a gas aspirator and a
dehumidifier are not required.
2. Easy maintenance
The sensor equipped with the detector, has unit construction, it is easy to replace.
By separating the detector and the flow guide tube, filter
replacement is easy.
3. More reliable than sensor diagnosis, sensor recoverable function
Depending on the concentration of the measurement gas,
the power of the sensor might deteriorate. The equipment
includes sensor recovery function electronically, checking
the deterioration status of the sensor depletion.
Therefore, it has high reliability and long-lasting stability.
4. Safe and secure
System detects thermocouple break for heater control on
the sensor side. Safety functions of isolating power supply
to the detector or isolating power via external contact input
are also.
5. Easy operation
The operation and setting for the converter can be performed interactively, and available as English, Japanese or
Chinese for language display.

• 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 below to above. And the flow guide tube
should be attached in the direction in which the gas flow
to the detector decreases.
• In the case of a refuse incinerator, automatic blow down
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.
