The Rosemount Analytical Model 6888 in-situ oxygen analyser provides accurate measurement of the oxygen remaining in the flue gases coming from combustion processes such as boilers, incinerators, kilns, process heaters and industrial heating furnaces. By maintaining the ideal level of oxygen in the flue gases, optimal efficiency is achieved and the lowest levels of NOX, CO, and CO2 are produced.
The in-situ design of Emersons’s Model 6888 places a zirconium oxide sensing element at the end of a probe which can be inserted directly into a flue gas stream. Probe lengths are available from 45 cm to 3.65 m, and a slip mounting option provides the ability to mount a long probe at any insertion depth. Signal conditioning electronics reside in the head of each probe, eliminating the need for an expensive signal cable. The Model 6888 is fully field-repairable. All active components can be replaced, including the diffuser/filter, sensing cell, heater and thermocouple, and all electronics cards. A dual-channel operator interface unit provides an easy-to-use method of set-up, calibration and failure diagnostics.
