Thermometer accuracy at small rise in temperature leads to increasing the knowledge about products process especially in drying of plants, fruits and biological laboratories. This developed model a thermometer based on capacitance change resulting from deflection of a bimetal cantilever. The effect of fringing field is included in the model. The deflection of the theoretical model is simulated and results are shown to closely follow the previously published results. Finally, the complete theoretical model, including the effect of fringing field, is simulated using an example. The Taguchi method with analysis of S/N ratio is used to obtain the optimal design of the sensor. Using the optimum settings, the S/N ratio improved by 24.11 dB.
