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 with an operating temperature that is above a flashpoint of process combustion fuel. The process probe includes a heater configured to heat the measurement cell to the operating temperature. Electronic circuitry is coupled to the measurement cell and to the heater. The electronic circuitry is configured to disengage power to the heater once process combustion heat is sufficient to maintain the measurement cell at the operating temperature and thereafter to maintain the heater in a de-energized state.

Method of operation an in SITU process probe

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.
