This manual describes how to properly install, use, and maintain Rosemount 6888Xi Advanced Electronics O2 Probes.
The Rosemount 6888Xi Advanced Electronics is designed to control a zirconium oxide probe for measuring oxygen, typically the O2 remaining from a combustion process. Key functions include heater control to maintain a setpoint of 736 °C, signal conditioning to provide a linear 4-20 mA output, automatic calibration using bottled gases, and diagnostic alarms to assist with troubleshooting.
| Heater Control Setpoint | 736 °C |
|---|---|
| Output Signal | 4-20 mA |
| Recommended Calibration Gases | 0.4% O2 and 8% O2 |
It is verified to operate Westinghouse 218 and World Class (115 V heater only), Rosemount Oxymitter and 6888, and Yokogawa probes.
It will not operate World Class (44 V Heater) or XSTREAM O2 Probe (Transmitter, Integral Electronics).
The 375 Field Communicator must be upgraded to System Software 2.0 with Graphic License, and AMS software must be upgraded to AMS 8.0 or above.
