Revolutionary zirconium oxide analyzer integrates oxygen probe and field electronics

SOLON, OHIO (June 14, 2007) – Emerson Process Management (NYSE: EMR), the leader in oxygen flue gas analyzer technology, recently introduced its latest innovation in zirconium oxide, in situ oxygen analyzers – the Rosemount Analytical® X-STREAM™ Oxygen Transmitter. Built from the company’s industry expertise and the latest Rosemount Analytical technology, the X-STREAM Oxygen Transmitter integrates an oxygen probe and field electronics into a single, compact package with unprecedented reliability. 

“The X-STREAM AccuMax™ enhanced system performance offers the best accuracy and stability of any analyzer we have ever produced,” said Doug Simmers, Product Manager for Rosemount Analytical. 

According to Simmers, today’s sustained fuel price increases are causing customers to operate boilers and furnaces with less excess oxygen in their flue gas in order to maintain the best efficiency, and also to lower nitrogen oxide (NOx) emissions.  

“Boiler operators are often hesitant to run at low oxygen levels,” said Simmers. “So, with the X-STREAM oxygen analyzer, we’ve added on-line diagnostics that predict when calibration is required; and new sensing technology provides an indication of oxygen deficiency during upsets when reducing conditions (zero percent oxygen) may occur.” 

Rosemount Analytical has also increased maximum flue gas temperature specifications to 850˚C (1562˚F) on the X-STREAM oxygen analyzer, permitting the placement of the probe closer to the actual combustion process. Integral electronics minimize the cabling and installation cost and the Oxycore™ active sensing core can be replaced in minutes without unbolting the probe flange or disconnecting the electrical terminations or pneumatic lines.  

“These new technologies make the X-STREAM analyzer less costly to install, operate and maintain,” Simmers said. “The X-STREAM oxygen analyzer is the most accurate and stable flue gas instrument available, and also offers the lowest cost to install, operate and maintain.”

The X-STREAM Oxygen Transmitter also uses HART® Communications with EDDL protocol, which provides a link to Emerson Process Management’s PlantWeb® digital architecture. Setup, calibration and service diagnostics can be performed remotely with the HART 375 Hand-held Communicator, AMS or via an optional single- or dual-channel Xi Enhanced Interface which carries advanced features such as automatic calibration, extended process temperature to 1,562°, a built-in stoichiometer feature and programmable reference.

The latest innovation from Rosemount Analytical, the X-STREAM Oxygen Transmitter is intended for measuring residual oxygen remaining in the flue gases from any combustion process, including boilers, process heaters, kilns, recovery boilers and reheat furnaces.
