The WDG 1200/Insitu and the WDG1210/Insitu are rugged, reliable flue
gas analyzers for net oxygen that use industry-proven zirconium oxide
sensor technology. The outer probe tube is 310 stainless steel so no
abrasion shield is needed for most applications. The controller features
precision temperature control foroptimum stability, built-in diagnostics,
and over-temperature protection. Modbus interface and 4-20 mA
outputs are standard. The unique sensor design allows the entire sensor
assembly, including the heater, to be removed without disturbing the outer
protection tube which remains in the process. This makes field service
fast and easy, and because there is no need to return the probe to the
factory for repair, there’s no expensive downtime.
