Assignee: ROSEMOUNT INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A process oxygen analyzer comprising:
a process probe extendible into a flow of process combustion exhaust, the process probe having an oxygen sensor measurement cell;
measurement circuitry coupled to the oxygen sensor measurement cell and configured to obtain a non-corrected indication of oxygen concentration relative to a combustion process based on an electrical characteristic of the oxygen sensor measurement cell;
a controller operably coupled to the measurement circuitry, the controller being configured to obtain an indication of process pressure and selectively provide a corrected oxygen concentration output based on non-corrected indication of oxygen concentration and the indication of process pressure
a user interface (UI)/display module operably coupled to the controller; and
wherein the controller is configured to obtain the indication of process pressure via the UI/display module.
