摘要:
An optical sensor system includes a multi-color pyrometer in optical communication with a component. The pyrometer generates signals at least partially representative of radiation received from the component and from soot particles. The system includes at least one processing unit coupled to the pyrometer. The processing unit is programmed to receive the signals and distinguish portions of radiation received between at least two wavelength bands. The processing unit is also programmed to determine that a first portion of radiation within a first of the wavelength bands is representative of a temperature of soot particles and that a second portion of radiation within a second of the wavelength bands is representative of a temperature of the component. The processing unit is further programmed to filter out signals representative of the first portion of the radiation.

A smart radiation thermometry system including a turbine component is provided. The thermometry system also includes at least one smart real time processing sub-system electrically coupled to at least one detector array via at least one high-speed multi-channel ADC. The at least one smart real time processing sub-system calculates temperature and emissivity of the turbine component based upon a computed radiance temperature, reflection correction and multi-wavelength algorithm. The smart real time processing sub-system also transmits data indicative of the temperature, emissivity and other plurality of parameters within a pre-determined time period to a communication unit. The smart real time processing sub-system also outputs emergency alarm signals and controls either directly or via a controller one or more actuators coupled to the gas turbine based upon the data to ensure optimum operation of the gas turbine within safe operating limits.
