Determination of Significant Parameters and Their Contributions In Temperature Measurement using Analysis of Variance and Taguchi Method

This work is devoted to the optimization of temperature measurement procedure by determination of the effect of significant parameters throughout the temperature measurement. The experimental studies result in Negative Temperature Coefficient thermistors, which will shed light on a critical point during temperature measurement. The results of experimental temperature measurement are presented by applying different tools in Design of Experiments (DOE), namely Taguchi method and Analysis of Variance (ANOVA). In the experimental studies, the effects of four parameters are considered, including the operator, air velocity, immersion level and the diameter of the probe. These parameters are chosen because in most test cases they are repeatedly involved. The results demonstrate that the probe diameter of the thermistor is the most significant factor with the percentage of contribution of 41.87%. Hence, Design of Experiment is considered as reasonable tool in finding the critical parameters and their contributions in temperature measurement.
