IN-SITU ZIRCONIA OXYGEN ANALYZER ZFK, ZRM DATA SHEET 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 monitoring 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, incomplete 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 functions 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 concentration and temperature of exhaust gas can be displayed as an optional function, which is useful to improve combustion efficiency. 5. Sampling device is unnecessary Gas sampling devices such as a gas aspirator, a dehumidifier, etc. are unnecessary because of use of directinsertion 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 detector 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.

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.
