Sensitivity Analysis of Sensor Probe for Low Thermal Diffusivity Properties Measurement

Abstract:

Single probe and dual probes are always taken adopt to measure the material's thermal conductivity and thermal diffusivity. The measurement principle of the two kinds of probes is different and introduced in this article. Taken the material which has low thermal diffusivity for example, the single probe and dual probes are compared by the calculation accuracy and temperature response sensitivity. Numerical simulation results show that, under the same conditions, the thermal properties obtained by the dual probes are closer to the true value for the test material, but single probe has more sensitive at temperature response.
