DEFOR Gas Analyzer

DEFOR Single or simultaneous measurement of SO2, NO, NO2, Cl2, NH3, CS2, COS, H2S and others gases The DEFOR is an extractive UV gas analyzer for simultaneous measurement of up to three components. It is a specialist for extremely selective NO-measurements of small ranges. It is a generalist for many UV-active gases like SO2, NO2, Cl2, NH3, CS2, H2S and COS. It shows no cross-sensitivities to CO2 and H2O due to the used spectral range. The innovative signal processing as well as the highly stable detectors provide an outstandingly longterm stability and allow the compensation of drifts and other effects. The state-of-the-art electronics and software provide the required interfaces for remote control via networks and integration into process control systems. Applications Cl2-measurement, also in combination with O2 Measurement of sulfur compound in process gases NO, NO2 and NH3 measurement in nitric acid synthesis H2S and SO2 measurement in sulfur recovery plants Measurement of high H2S concentrations in reactive and acidic gases Measurement of H2 in Cl2 or vice versa Technical specification Measuring principle NDUV spectroscopy Measuring components Cl2, COS, CS2, H2S, NH3, NO, NO2, SO2 Number of components 3 Measuring ranges Cl2: 0 ... 125 ppm / 0 ... 100 vol% COS: 0 ... 250 ppm / 0 ... 100 vol% CS2: 0 ... 50 ppm / 0 ... 30 vol% H2S: 0 ... 25 ppm / 0 ... 100 vol% NH3: 0 ... 50 ppm / 0 ... 100 vol% NO: 0 ... 10 ppm / 0 ... 100 vol% NO2: 0 ... 10 ppm / 0 ... 100 vol% SO2: 0 ... 10 ppm / 0 ... 100 vol% Sample gas temperature 0 ... 45 ° C ( 32 ... 113 ° F) Sample gas pressure -200 ... 300 hPa, refering to ambient pressure Ambient temperature 5 ... 45 ° C ( 41 ... 113 ° F) Ex-approvals Wall mounting enclosure: II 2 G Ex px IIC T6; II 3 G Ex nR IIC T6; II 3 G Ex pz IIC T6 Electrical safety CE, EMC, LVD Enclosure rating 19" -rack: IP 40 wall mounting enclosure: IP 65 Analogue outputs 4 outputs: 0/ 2/ 4 ... 20 mA, 500 Ohm, electrically isolated Analogue inputs 2 inputs: 0 ... 20 mA, not electrically isolated Digital outputs 8 outputs: 34 V AC, 0.5 A 48 V DC, 0.5 A Digital inputs 8 inputs: 42 V, all inlets with common GND Interfaces Ethernet, extendanble via interfaces of the SCU control unit Bus protocol OPC ( Option) , via SOPAS Operation via display or software SOPAS Device types 19' ' -rack, wall mounting enclosure Test functions optional adjustment unit
