Automatic Calibration
Communication Options
Calibrations consist of introducing bottled gases of known value into the probe so the electronics can make automatic adjustments to the O2 readings to match the bottled gas value. 0.4% O2 and 8% O2 (balance nitrogen) gases are recommended. Never use nitrogen or instrument air as calibration gases.
Flowmeters (for calibration gases) and regulators and flowmeters (for reference air) are available as loose components, mounted into an optional manual calibration switching panel, or as a fully automatic calibration system, Figure
Data Communications
An operator can configure and troubleshoot the O2 Probe system in one of two ways:
1.Using the Xi Advanced Electronics the Xi carries the following optional advanced features:
•Fully automatic calibration
•Flame safety interface
•High temperature operation [above 700° C (1292° F) standard temperature].
•Stoichiometer feature provides the ability to indicate O2 efficiency when the combustion process goes into reducing conditions (0% O2).
•Programmable reference provides enhanced accuracy when measuring at or near O2 level (20.95% O2).
2.Using the HART Interface. The Xi’s
•Rosemount Analytical Model 375/475 Field Communicator - The handheld communicator requires Device Description (DD) software specific to the Xi. The DD software will be supplied with many Model 375/475 units but can also be programmed into existing units at most Emerson Process Management service offices. See Section 4, Startup and Operation, for additional information.
•Personal Computer (PC) - The use of a personal computer requires AMS software available from Emerson Process Management.
•Delta V and Ovation Distributed Control System (DCS) with
NOTE:
The 375 Field Communicator must be upgraded to System Software 2.0 with Graphic License for operation with the Xi. The AMS software must be upgraded to AMS 8.0 or above.
