Abstract

The dynamic characteristics evaluation of thermocouples presents a challenging problem for temperature measurement. The authors have recently proposed a novel difference-based cascade thermocouple measurement system that consists of three thermocouples with different time constants. The combination of the test system with use of the Tikhonov algorithm for parameter identification provides excellent time constant estimation despite the lack of any a priori assumption on the time constant ratios of the thermocouples. The developed scheme has been tested in a generator of a step excitation temperature signal device with constant flow and the simulated results show that the proposed scheme is effective.
