infrared gas analyzer for stic gas this infrared gas analyzer (zsk) is composed of gas ana- lyzer units, oxygen sensor and gas sampling equipment. it is capable of continuous measuring concentration of gases such as nox, so 2 , co, co 2 and o 2 contained in the ue gas generated from various boilers or garbage incinerators. features 1. gas concentrations of 5 components measurable simultaneously and continuously the infrared ray method has integrated the measurements of nox, so 2 , co and co 2 and the gas concentrations of 5 components can be measured simultaneously and continuously with the zirconia oxygen analyzer. 2. a high-sensitivity mass ow sensor is used in the detector unit of infrared method. due to use of single beam system for measurement, maintenance is easy and an excellent stability is ensured for a long period of time. 3. space-saving con guration is available with the maintenance from the front structure the main unit is downsized by half of that of the conven- tional product. the complete maintenance from the front makes it easy to use. 4. the analyzer has a host of capabilities provided with a variety of functions such as o 2 correction output, average value output, auto calibration, auto range selection, alarm, etc. specifications standard speci cations ?measuring principle: nox, so 2 , co, co 2 : non-dispersive infrared absorption (ndir) method o 2 ; zirconia system measurable component and min./max. measuring range: nox : 0 to 200ppm/0 to 5000ppm so 2 : 0 to 200ppm/0 to 5000ppm co : 0 to 200ppm/0 to 5000ppm co 2 : 0 to 10%/0 to 20% o 2 : 0 to 10%/0 to 25% ?measuring range: max. range ratio 1:10 (see code sym- bols.) ?warm-up time: 4 hours or less after power on ?analog output signal: 4 to 20ma dc simultaneous output for each (non-isolated or isolated: as speci- ed by code symbols) ?instantaneous value output (nox, so 2 , co, co 2 , o 2 ) 5 points ?instantaneous o 2 correction value (nox, so 2 , co) 3 points * provided with o 2 ?o 2 correction average value (nox, so 2 , co) 3 points * provided with o 2 ?allowable load resistance: 550 or less (750 or less for insulation out- put) ?contact output: (1) 1a contact for each (contact capacity: 250v ac 2a, 30v dc 3a) ?range identi cation for each compo- nent, analyzer unit error, calibration error, during automatic calibration, during maintenance (2) 1c contact for each (contact capacity: 250v ac 1a, 30v dc 1a) ?instantaneous/concentration value alarm for each component (h, l, hl can be set). data sheet zsk EDS3-136 nov. 14, 2007 date
