METHOD AND SYSTEM FOR GAS TEMPERATURE MEASUREMENT

摘要

A temperature measurement system includes a plurality of filaments. The plurality of filaments are configured to emit thermal radiation in a relatively broad and substantially continuous wavelength band at least partially representative of a temperature of the plurality of filaments. A first and second portion of the filaments has a differing first and a second diameter and/or emissivity, respectively. The system also includes a detector array configured to generate electrical signals at least partially representative of the thermal radiation received from the filaments. The system further includes a controller communicatively coupled to the detector array configured to transform the first electrical signals to a first temperature indication at least partially as a function of the first diameter and/or first emissivity and transform the second electrical signals to a second temperature indication at least partially as a function of the second diameter and/or emissivity.

1. A temperature measurement system comprising:
a plurality of filaments configured to emit thermal radiation in a relatively broad and substantially continuous wavelength band at least partially representative of a temperature of said plurality of filaments, wherein:
at least a first portion of said plurality of filaments has at least one of a first diameter and a first emissivity; andat least a second portion of said plurality of filaments has at least one of a second diameter that is different from the first diameter and a second emissivity; an optical system configured to receive at least a portion of the thermal radiation emitted from said plurality of filaments, said optical system comprising a detector array configured to:
generate first electrical signals at least partially representative of the thermal radiation received from said first portion of said plurality of filaments;generate second electrical signals at least partially representative of the thermal radiation received from said second portion of said plurality of filaments; and a controller communicatively coupled to said detector array, said controller configured to:
transform the first electrical signals to a first temperature indication at least partially as a function of at least one of the first diameter and the first emissivity; andtransform the second electrical signals to a second temperature indication at least partially as a function of at least one of the second diameter and the second emissivity.
