1 IN-SITU ZIRCONIA OXYGEN ANALYZER < ZIRCOMAT-C > DATA SHEET ZFK, ZRY 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 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 (ZRY) features 3 measuring ranges, one touch calibration and NEMA4 housing. Comparing to the current converter (ZRM), this ZRY is recognized as economical type with simple functions. General-use detector FEATURES. Sampling device is unnecessary Gas sampling devices such as a gas aspirator, a dehumidifier, etc. are unnecessary because of use of directinsertion type detector.. High speed response The adoption of a flow guide tube utilizing the flow of the measured gas assures quick response (less than 7sec). 3. Dust-tight and water-proof housing Aluminum die casting housing of converter satisfies NEMA4 and IP6 standard measuring ranges and one touch calibration The converter has 0-, 0, vol% 3 ranges easily changed by pin connection and zero and span are simply calibrated by key operation.

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 + C). The flow guide should be attached in the direction in which the gas flow to the detector decreases. When dust more than g/nm 3 is included in the gas, manual blow down is necessary. The product conforms to the requirements of the Electromagnetic compatibility Directive 89/336/EEC as detailed within the technical construction file number TZ The applicable standards used to demonstrate compliance are : EN 0 : 99 CLASSA Conducted and Radiated emissions EN 008- : 99 Radiated immunity, ESD and FBT ZFK, ZRY
