Abstract
A thin-film sensor operating in transient mode in principle enables very accurate
temperature measurements to be obtained, e. g. in turbine blades, because of the
high frequency of its response; however, the complexity of data processing is the
major drawback for popular use of the sensor.
In this study new data processing methods are presented, including a comprehensive
1–D finite element model which is convenient both for its capability of
dealing with general boundary conditions and for the low computational cost as
compared to present transform–based methods.
This method can also tackle single-, double- and multi-layer sensors, can support
temperature dependent quantities and proves successful in processing prototype
signals in a wide range of
