IN-SITU
ZIRCONIA OXYGEN ANALYZER
ZSB
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 moni-toring and control.
The analyzer consists of a flow guide tube with a
detector, which is directly inserted into a flue, etc. to
introduce the gas to be analyzed, a transducer, which
performs control, signal processing, display, input to
and output from outside, and communication, and an
auto calibration/blow unit. The detector of a unit sensor
structure facilitates on-site maintenance. The transducer
provided with an unconventional sensor diagnostic
function and sensor renewal function ensures long-term
stable detecting operation.
FEATURES
1.No need for gas sampling devices
Since the sensor unit is directly inserted into a flue,
etc., gas-sampling devices such as gas aspirator and
dehumidifier are not required, which ensures high
response speed.
2.Easy maintenance
The sensor in a unit structure mounted to the detector can be replaced easily. Since the detector and
the flow guide tube are installed separately, the filter
at the tip of the detector can be replaced easily, and
detector and the flow guide tube can be maintained
separately depending on the degree of formation of
rust, for example.
3.High reliability ensured by the sensor diagnostic and
sensor renewal functions
Depending on the components in the gas to be
measured, the sensor electrode may degrade. The
transducer diagnoses the degree of degradation of
the sensor and renews it electrically, thus ensuring
high reliability and long-term stable measurement.
4.Improved safety
Detecting a break of the thermocouple for heater control installed at the sensor, power supply to the detector is stopped. Furthermore, external contact input
stops power supply to the detector in an emergency.
Those functions along with the key lock function are
equipped as standard to ensure improved safety.
5.Simple operation
The transducer can be operated and various settings
can be made using an interactive system, and display
language is available in English, Japanese, and Chinese.

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
(+300ºC or higher), the flange should be separated
from the furnace wall in order to bring the detector
flange surface temperature below the specified
value (+125ºC). The flow guide tube should be
attached in the direction in which the gas flow to
the detector decreases.
·If much dust is contained in the gas, the flow
guide tube should be connected obliquely from
the top. This tube should also be connected in the
direction where gas flow into the detector section
is reduced.
·In application to refuse incineration, automatic
blow-down of the flow guide tube should be avoided (in order to protect the tube from corrosion due
to drain formation). Blow-down should be carried
out manually when indication change becomes
small during stop of the incinerator.
