Measurement of a surface temperature distribution using multi-element resistance sensor

This paper presents some aspects of a spatial temperature distribution measurement using a planar multi-element resistance sensor. Metrological characteristics of this sensor are described and investigated in detail. The parameters of 16 channel data acquisition system based on Siemens 6ES7531-7KF00-0AB0 module are reviewed. The technique of a spatial temperature distribution reconstruction based on its previous approximation and the solution of inverse problem is considered in detail. A simulation of a temperature distribution reconstruction and errors are presented and analyzed.
