The Rosemount Analytical Oxymitter 5000 Oxygen Transmitter is the world's first in situ, zirconium oxidebased oxygen transmitter for flue gas measurement. These oxygen measurements can be used in a control system or by a boiler operator to fine tune burner fuel/air ratios for maximum efficiency. Ideal for:

  • Boilers
  • Kilns
  • Process heaters
  • Reheat furnaces

Rosemount Analytical is the leader in oxygen flue gas analyzer technology. The Oxymitter 5000 integrates an oxygen probe and field electronics into a single, compact package.

FOUNDATION fieldbus communications provide operators with constant updates of all critical parameters and diagnostics with no additional wiring. The probe inserts directly into a flue gas duct to measure oxygen in combustion processes. No sampling system is required.

A NEMA 4X, IP66 Rosemount transmitter housing mounts directly to the probe and contains the transmitter's electronics, replacing common stand-alone field electronics. This integrated design minimizes the costs of installing separate probe cable, conduit, and electronics. The Oxymitter 5000's electronics also require 95% less power to operate. Therefore, its components last longer.

The FOUNDATION fieldbus protocol provides a link into Emerson Process Management's PlantWeb® field-based architecture. Instrument technicians can interface with the Oxymitter from the operator console in the control room. Service diagnostics and calibrations can be performed remotely.

The Oxymitter 5000 is fully field-repairable. The probe's design provides convenient access to internal probe components so technicians can service the unit in house. The cell and heater/thermocouple are fully field-replaceable. The Oxymitter 5000 contains no potentiometer adjustments or jumpers.

The Oxymitter 5000 Oxygen Transmitter operates at process temperatures up to 1300°F (700°C), providing a fast response with high accuracy and reliability. Available in lengths from 18 inches (457mm) to 12 feet (3.66m).
