System Features
The WDG 1200/1210 Insitu probes are a type of direct insertion oxygen probe
used to measure the oxygen in the exhaust of a combustion process. The zirco-
nium oxide cell is placed directly in the stream of the products of combustion.
The probe is designed for applications in which the flue gas temperature does not
exceed 1472°F (800°C), and where combustibles measurements are not required.
The outer probe material is 310L stainless steel, which is highly resistant to cor-
rosion.
With the unique design of the Insitu probe, field replacement of all components
is easily performed. While the outer protection tube remains in the process, the
inner tube structure, which houses the oxygen cell and furnace/thermocouple
assembly, can be removed easily (see Figure 6-1). Because there is no need to
return the probe to the factory, extensive downtime and expensive repairs on the
probe are no longer necessary.
