Rosemount 6888 In Situ Oxygen Transmitter

Description

The Rosemount 6888 Oxygen Transmitter provides accurate measurement of the oxygen remaining in the flue gases coming from any combustion process. Optimal combustion efficiency can be obtained by maintaining the ideal level of oxygen in the flue gases coming from these processes and the lowest level of NOX, CO and CO2 are produced. Easy to use and easy to integrate. This in situ analyzer was designed with customer ease-of-use in mind. There are no moving parts or sampling apparatus resulting in an extremely reliable probe that requires very little maintenance. The 6888 in situ O2 analyzer provides accurate measurement of the oxygen remaining in the flue gases coming from any combustion process, including: This in situ design places a zirconium oxide sensing element at the end of a probe, which inserts directly into a flue gas stream. There are no moving parts or sampling apparatus, resulting in an extremely reliable analyzer that requires very little maintenance. Probe lengths are available from 18″ to 12′, and a slip mounting option provides the ability to mount a long probe at any insertion depth. Heavy-wall probe tubes are available for applications where fly-ash erosion is a problem. Accessories are available for process temperatures above 700°C to 1050°C. Calibrations may be performed on-line, while the furnace is in operation, and fully automated calibration with solenoid switching is also available. The 6888 is fully field repairable. All active components can be replaced, including the diffuser/filter, sensing cell, heater and thermocouple, and all electronics cards. Signal conditioning electronics reside in the head of each probe, eliminating the need for expensive signal cable. A dual-channel operator interface unit provides an easy-to-use method of setting up the instrument, calibrating, and diagnosing failures.
