This paper describes the approach towards signal processing characteristics for temperature fluctuations from a fast thermocouple located above fuel subassemblies of fast reactor. Simulated temperature profile denoting various power levels was fed to the FPGA and the RMS value at each power level was calculated in real time. The technique mentioned in the paper helps in the analysis of reactor ...

Thin film thermocouples (TFTCs) can provide more precise in situ temperature measurement for aerospace propulsion systems without disturbance of gas flow and surface temperature distribution of the hot components. ITO/PtRh:PtRh TFTC with multilayer structure was deposited on alumina ceramic substrate by magnetron sputtering. After annealing, the TFTC was statically calibrated for multiple cycle...

A scanning thermal microscope working in passive mode is described. This tool uses a thermocouple probe and is presented as a thermal imaging system. The surface temperature distribution of a thermal micro-component is presented. We point out the capacity of our system to perform surface temperature images under conditions for which most of usual techniques cannot operate. The thermal microscop...

An implementation of a two-stage piece-wise linearization method for reduction the thermocouple approximation error is presented in paper. First, whole measurement chain transducer described, and possible analysed to define required level accuracy transfer characteristics. Evaluation functions analysis errors are performed by virtual instrumentation software package LabVIEW. The appropriate the...
