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 EHand ELrespectively, recording a first radiation measurement from the first emissivity coating RHand a second radiation measurement from the second emissivity coating RL, then calculating the true radiation RBladefrom the component from the equationRBlade=(RHEH-RLEH⁢(1-EH1-EL))(1-ELEH⁢(1-EH1-EL))and relate the RBladevalue to the true component temperature by calibration of the pyrometer.
