This study deals with theoretical analysis of the frequency response of thermistors and a compensation technique for the delay of the response. A "two-thermocouple probe technique" developed previously (Tagawa & Ohta, 1997) was applied to the identification of the time-constants of thermistors whose frequency response approximate a first-order system. Two different thermistors were combined into a probe, and the schemes for the time-constant identification and for the response compensation were tested in two working fluids of water ans air. The results show the compensation technique to be successful.
