ABSTRACT:
In an industrial installation equipped with a sensor, a method is provided for checking the sensor and providing a measurement sequence associated with the sensor. Monitoring occurs for a thermodynamic parameter of a monitored fluid circulating in the industrial installation, by sensing the fluid using the sensor while the industrial installation is operating and by collecting and processing an electric signal emitted by the sensor using the measurement sequence. A perturbation is produced of fluid origin of the thermodynamic parameter while the installation is operating and the fluid circulates in the installation in order to act on a sensitive element of the sensor and cause a modification of the electric signal emitted by the sensor. The method performs collecting and analyzing of the modified signal from the sensor using the measurement sequence.
