Abstract
(EN)
A process combustion transmitter (10) is provided. The transmitter (10) includes a process probe (12) extendible into a flow of process combustion exhaust. The process probe (12) has a measurement cell (36) and a diffuser (32) that define a chamber (52) within the process probe. Electronic circuitry (42) is coupled to the measurement cell (32) and is configured to provide an indication relative to a combustion process based on an output signal of the measurement cell (32). A pressure sensor (50) is coupled to the electronic circuitry (42) and is fluidically coupled to the chamber (52). The electronic circuitry (42) is configured to provide an adjusted calibration based on pressure measured within the chamber (52) during a calibration.

L'invention porte sur un émetteur de combustion de processus (10). L'émetteur (10) comprend une sonde de processus (12) extensible dans un flux d'échappement de combustion de processus. La sonde de processus (12) possède une cellule de mesure (36) et un diffuseur (32) qui définissent une chambre (52) à l'intérieur de la sonde de processus. Une circuiterie électronique (42) est couplée à la cellule de mesure (32) et est configurée pour fournir une indication relative à un processus de combustion sur la base d'un signal de sortie de la cellule de mesure (32). Un capteur de pression (50) est couplé à la circuiterie électronique (42) et est couplé de manière fluidique à la chambre (52). La circuiterie électronique (42) est configurée pour fournir un étalonnage ajusté sur la base de la pression mesurée à l'intérieur de la chambre (52) durant un étalonnage.
