data sheet zfk, zrm general measuring object: oxygen contained in noncombustible gas measuring principle: direct-insertion zirconia system measuring range: 0 to 2 50 vol% o 2 freely settable (in 0.5% steps) repeatability: within 0.5% of max. output signal 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 of general-use detector) 15 + 200va (at start of general-use detector) warmup time: approx. 15min oxygen detector (zfk2,5), ejector (zta) measuring detector: for general-use: zfk2 for corrosive gas: zfk5 converter 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. 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. general-use detector high-temperature detector in-situ zirconia oxygen analyzer < zircomat-p > features specifications date EDSX3-113C nov. 30, 2001
