Model WDG Insitu Probe



The THERMOC Model WDG Insitu flue gas oxygen probe differs from all other oxygen insitu probes. The unique inner/outer probe design facilitates removal of cell, heater and thermocouple assembly through the probe head. Once the inner probe assembly is removed, the outer probe support pipe allows straight run access to insitu filter for cleaning with compressed air. The inner probe assembly also exposes the reference side of the zirconium cell to ambient air eliminating the need for instrument air utilities at the probe mounting location. The combination of component access and reduced utility requirements provides a cost-effective reduced maintenance solution for today and tomorrow’s gas, oil and coal fired boiler operations.


      • There are two control options available for the WDG Insitu flue gas oxygen probe to maximize integration with existing plant or process control system:

    -2000 Series Microprocessor Control provides 4 line local display, analog outputs, alarms, expanded system diagnostics, auto calibration option.


      •     -1200/1210 Series Compact Control provides 2 line local display, one analog output, alarms, general system diagnostics, software supported manual calibration.


  • Completely field serviceable.
