The Rosemount Oxymitter 4000 explosion proof oxygen transmitter is the world's first in situ, zirconium oxide-based 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:
- Process heaters
- Reheat furnaces
Emerson Process Management is the leader in oxygen flue gas analyzer technology. Their in situ, zirconium oxide oxygen analyzers have long been established as industry standards. They've combined their expertise with the latest Rosemount transmitter technology to create a truly revolutionary package, the Oxymitter.
The Oxymitter integrates an oxygen probe and field electronics into a single, compact package. The probe inserts directly into a flue gas duct to measure oxygen in combustion processes. No sampling system is required.
A NEMA 4X, IP 66 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 for harzardous areas is rated ATEX II 2G Exd IIB +H2 T4 Gb– Class I, Div. I, Groups B, C and D.
The Oxymitter electronics also require 95% less power to operate. So, its components last longer. Traditional architecture with remote-mounted electronics is also offered.
The HART protocol provides a link into Emerson Process Management's PlantWeb field-based architecture. Instrument technicians can interface with the Oxymitter from the control room or any location where the transmitter's signal wires terminate. Service diagnostics and calibrations can be performed remotely with a HART hand-held communicator or a personal computer equipped with AMS.
The Oxymitter 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 contains no potentiometer adjustments or jumpers.
The Oxymitter In Situ Oxygen Transmitter operates at process temperatures up to 1300°F (700°C), providing a fast response with high accuracy and reliability. Available lengths from 18 inches to 6 feet.
