Abstract
A method of measuring temperature of a component capable of emitting thermal radiation and reflecting background radiation having the steps of: providing a pyrometer for measuring the radiation from the component, characterised by coating a part of the component with a first emissivity coating and a part of the component with a different and second emissivity coating, each with known emissivities Eand Erespectively, recording a first radiation measurement from the first emissivity coating Rand a second radiation measurement from the second emissivity coating R, then calculating the true radiation Rfrom the component from the equationand relate the Rvalue to the true component temperature by calibration of the pyrometer.
