A sensing system is provided. The sensing system includes a processor, a sensor node, a plurality of sensors, a power source and a controller. The sensor node is operably connected to the processor on an industrial side and to the sensors on a sensor side. The sensors each measure a parameter of the sensing system and transmit the parameter to the processor via the sensor node. The power source delivers power to the processor. The controller is in operable communication with the processor. The sensor node, disposed in close proximity to the sensors, converts a data protocol for each of the sensors to a different industrial protocol and transmits the converted data through a communication port via the industrial data protocol to the processor. The processor then collects the measurements of each parameter of the plurality of sensors, analyses the measurements and transmits the analyzed data to the controller.

There is described an oil contamination detection system and method. The system comprises a forward sensor package, a rearward sensor package, a catalytic chamber, and a computing device. The method comprises obtaining sensor measurements from the forward sensor package and the rearward sensor package, and detecting the presence of oil in the air flow from the sensor measurements.

The present disclosure refers to a method for operating a gas turbine having a compressor, a combustor, a turbine downstream of the combustor, and a total number of turbine outlet temperature measurement sensors. The method can include supplying a first fuel flow to one of the burners of one combustor, which is smaller than a second fuel flow to another one of the burners the same combustor, selecting a number of turbine outlet temperature measurements which is smaller than a total number of the turbine outlet temperature measurement sensors, and averaging measured temperatures of the selected turbine outlet temperature measurements to obtain an trimmed turbine outlet temperature which is used for controlling operation of the gas turbine.

A method is disclosed for operating a gas turbine having a compressor, a combustor, a turbine downstream of the combustor, and a total number of turbine outlet temperature measurements. The method includes locally measuring the turbine outlet temperature of the turbine with the turbine outlet temperature measurements of the respective turbine, and averaging measured temperatures of the selected turbine outlet temperature measurements to obtain an average turbine outlet temperature. The gas turbine operation is controlled depending on the determined average turbine outlet temperature.
