NEMA 3R standard lift-off enclosure

NEMA 4X optional hinged enclosure

Process gas is drawn into the analyzer�s primary sample loop byan aspirator and returns to process. Gas enters the split flow blockthat is separated by a baffle and contacts the catalytic combustiblesand methane detector. It then passes to the zirconium oxide cell,where the oxygen concentration is measured, before returning tothe main sample loop and then back to the process.

Convection Loop Operation

Designed for applications with high particulate levels in the gas stream,the analyzer mounts directly on the combustion process to providecontinuous measurement of oxygen (WDG-HPII) or oxygen and com-bustibles (WDG-HPIIC). This analyzer is suitable for gas streams up to1300°F (704°C) using the standard 316SS probe/filter assembly. Flue gastemperatures up to 2800°F (1537°C) can be measured using optionalhigh temperature probes. For corrosive gas streams, sample wettedparts in Hastelloy or Inconel are available. The analyzers can be pro-vided in a range of mounting styles. For hazardous area locations,purged or explosion proof versions are available.

APPLICATIONS

Convection Principle

Since the sample inlet and return are inside the filter and at the sameabsolute pressure as the process, there is no flow through the filter. Theflue gas oxygen diffuses through the filter and the sample in the filterflows through the sensor plumbing because of a convective motiveforce. The sample in the vertical cell housing is heated to 1283°F (695°C)while the sample in the return vertical tube is at about 480°F (249°C).This temperature difference generates a density difference whichcirculates the gas through the system. Process gas enters and replen-ishes the gas inside the filter by diffusion only. Thus the filter neverblocks, making it ideal for high particulate applications.

In addition, you can calibrate locally by manuallypressing keys on the Series 2000 or IQ Link.

Excess Fuel Software OptionMONITOR COMBUSTION PROCESSES THAT OPERATE IN EXCESS FUEL ATMOSPHERES

Automatic Calibration OptionSIMPLIFIES CALIBRATION OF ANALYZER

Similarly, a verification can be performed in which the calibration gas valuesare recorded but no changes are made to the calibration settings in the ana-lyzer.

Automatic calibration capabilities can be easily added to an analyzer at a laterdate by simply plugging a Calibration Module into the Series 2000 or IQanalyzer and installing a Remote Calibration Unit near the sensor.

Remote Calibration Unit

Theory of OperationIn the absence of molecular oxygen, the zirconium oxide cell responds to minute amounts of oxygen pro-duced by the dissociation of water or carbon dioxide at the high cell operating temperature. This dissociationis inhibited by the presence of combustibles in the sample gas. As the combustibles concentration increases,the oxygen concentration decreases, and the output signal from the cell becomes greater. This means that thecell keeps responding when there is no net oxygen in the flue gas. In fact, it becomes a sensor of net combus-tibles.

FEATURES

n User-selectable inputs include defining the hydro-gen-to-carbon ratio (H/C) of the fuel or selecting froma menu of common fuels

n Alarms can be set for high or low readingsn Analog output and display scalable to cover com-
