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 confi guration includes the detector fl ow guide tube and
detector sensor. The fl ow 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

fl ue Gas sampling functions such as a gas aspirator and a
dehumidifi er are not required.

2. Easy maintenance

The sensor equipped with the detector, has unit construc-

tion, it is easy to replace.

By separating the detector and the fl ow guide tube, fi lter

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 per-

formed interactively, and available as English, Japanese or
Chinese for language display.

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 fl ange surface
temperature below the specifi ed value +125°C). The fl ow
guide should be attached in the direction in which the gas
fl ow to the detector decreases.

• When much dust is included in the gas, the fl ow guide

tube should be attached at an inclination so that the fl ow
goes from below to above. And the fl ow guide tube
should be attached in the direction in which the gas fl ow
to the detector decreases.

• In the case of a refuse incinerator, automatic blow down

of the fl ow guide should not be performed (to prevent
corrosion of the fl ow guide tube due to drainage). Blow­down should be performed manually when change in
the indication has become very little with the furnace
stopped.
