EDSX3-113C Datasheet, PDF (1/12 Pages) Fuji Electric – IN-SITU ZIRCONIA OXYGEN ANALYZER

IN-SITU ZIRCONIA OXYGEN ANALYZER <ZIRCOMAT-P>
DATA SHEET
ZFK, ZRM
This oxygen analyzer is used to continuously measure
oxygen concentration in combustible exhaust gas of industrial
boilers or furnaces, and is ideally suited for combustion moni-
toring and control.
The detector (ZFK) used with the analyzer is directly
inserted into the objects measured, eliminating the need for a
sampling device and provides quick response.
The converter (ZRM) features automatic calibration and
blowdown functions. The adoption of liquid crystal display
facilitates operation and setting in interactive mode.
Besides the general-use type detector, corrosion resisting
type and high temperature type are available for selection
according to applications.
General-use detector
High-temperature detector
FEATURES
1. Output range easily set
Output range can be easily set in 0.5% increments within
the scope of 2 to 50%. When oxygen decreases, in-
complete combustion level appears on the display (rich
mode; output voltage of oxygen detector), instead of
oxygen concentration.
2. Automatic calibration/blowdown function
Automatic calibration and manual/auto blowdown func-
tions are provided as standard functions. An external
solenoid valve is required.
3. Easily operated in interactive mode
Interactive mode is adopted to the liquid crystal display for
operation and parameter setting, facilitating use even for
beginners.
4. Combustion efficiency display function
Combustion efficiency calculated from oxygen concent-
ration and temperature of exhaust gas can be displayed as
an optional function, which is useful to improve combus-
tion efficiency.
5. Sampling device is unnecessary
Gas sampling devices such as a gas aspirator, a dehu-
midifier, etc. are unnecessary because of use of direct-
insertion type detector. The adoption of a flow guide tube
utilizing the flow of the measured gas assures quick
response (less than 7sec).
6. Selection of detector type according to applications
Besides the general-use type detector used under
temperatures of less than 600°C, a corrosion-proof de-
tector for measuring incinerator exhaust gas, and a high
temperature type detector using heat insulator for the
ejector and insertion tube, capable of measuring
temperatures up to 1590°C, are available for selection
according to applications.
