Motor vehicle turbocharger rotating turbine blade temperature sensor light guide receiver calibration procedure uses adjacent calibration surface with thermo sensor in static operating conditions

摘要

A rotating turbine (1) blade temperature sensor light guide receiver calibration procedure constructs a calibration curve by comparing thermographic heat radiation from an adjacent fixed calibration surface (8) in identical material using thermography (3) and a thermo sensor (14) temperature in static operating conditions : Independent claims are included for equipment using the procedure and for a subsidiary calibration step measuring the opacity of the optical window.
