Abstract
A process combustion transmitter is provided. The transmitter includes a process probe extendible into a flow of process combustion exhaust. The process probe has a measurement cell and a diffuser that define a chamber within the process probe. Electronic circuitry is coupled to the measurement cell and is configured to provide an indication relative to a combustion process based on an output signal of the measurement cell. A pressure sensor is coupled to the electronic circuitry and is fluidically coupled to the chamber. The electronic circuitry is configured to provide an adjusted calibration based on pressure measured within the chamber during a calibration.
