IN-SITU

ZIRCONIA OXYGEN ANALYZER

FOR HAZARDOUS LOCATION

DATA SHEET

This oxygen analyzer is used to continuously measure
oxygen concentration in noncombustible 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 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 (ZKME) 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.

ZFKE, ZKME

Detector (ZFKE)

FEATURES

1. Gas sampling device is unnecessary

For quick response, insert the detector directly into the

staek. 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 construc-

tion, 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 components in the measurement

gas, the characteristics 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 isoralting 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, H
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 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.
