data sheet zfk, zry general measuring object: oxygen contained in noncombustible gas measuring principle: direct-insertion zirconia system measuring range: 0 to 5, 10 or 25 vol% o 2 (changed by internal set pin) repeatability: within 1.0% of full scale linearity: 2% of full scale response time: within 7sec for 90% response (from calibration gas inlet) power supply: 100, 115, 220 or 230v ac, 50/60hz power consumption: (approx.) 15 + 50va (at steady state) 15 + 200va (at start) warmup time: approx. 15min 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 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. 1. 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. 2. 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 ip65 standard. 4. 3-measuring ranges and one touch calibration the converter has 0-5, 10, 25 vol% 3 ranges easily changed by pin connection and zero and span are simply calibrated by key operation. in-situ zirconia oxygen analyzer < zircomat-c > features specifications oxygen detector (zfk2, 5) measuring detector: for general-use: zfk2 for corrosive gas: zfk5 measured gas temperature: flow guide tube system; ?0 to +600 c measured gas pressure: ? to +3kpa flow guide tube: flange; jis5k 65a ff (jis5k-80aff for high particulate gas) insertion length; 0.3, 0.5, 0.75, 1m (0.8m for high particulate gas) ambient temperature: ?0 to +60 c for cable section 125 c or less at detector flange surface with power applied structure: dust/rain-proof structure(iec ip55 equivalent) filter: alumina(filtering accuracy 50 m) and quartz paper main materials of gas-contacting parts: general-use detector(zfk 2); zirconia, sus316, platinum, sus304 anticorrosive detector(zfk 5); zirconia, tita-nium, platinum, sus316 flow guide tube; sus304 or sus316 general-use detector converter date EDSX3-119B mer. 6, 2007
