A robust response-compensation scheme has been developed to estimate in situ the thermal time constants of fine-wire temperature sensors in the frequency domain. The time-constant values can be obtained by maximizing a coherence function of two “compensated” temperature signals measured simultaneously by two sensors having different time constants. The scheme was validated experimentally and showed the highest tolerance to instrumentation noise compared with our previous methods.
