Abstract
An apparatus and method for determining a temperature in a system having an object, an optical sensor, and a gas flow passing between the object and the optical sensor, sensing, with the optical sensor, a wavelength emitted from the object and indicative of an attenuation, sensing, with the optical sensor, a wavelength emitted from the object and indicative of a temperature of at least one of the object or the gas; and calculating a temperature of the gas using the wavelengths.
Claims16
A thermal measurement system for determining a temperature of a gas disposed around an object, the thermal measurement system comprising:
- an optical sensor spaced from the object a predetermined distance, the optical sensor comprising an attenuation filter associated with an attenuation of the optical sensor determined by an attenuation wavelength reaching the optical sensor from the object after having passed through the gas;
- an optical detector for translating a wavelength signal, including the attenuation wavelength, into a transmitted signal;
- a storage for storing a set of parameters, including at least an emissivity value associated with the object;
- and
- a processor configured to:
- receive the transmitted signal,
- determine at least one parameter associated with the transmitted signal from the set of parameters,
- determine a fouling factor based on the attenuation wavelength, and
- calculate a gas temperature of the gas utilizing at least the fouling factor and the at least one parameter.
