A New Constant Power Line Heat-Source Temperature Sensor for Determining the Thermal Conductivity of Porous Mediums

[摘要] A new constant power line heat-source temperature sensor was developed at Harbin Institute of Technology (HIT), China. This sensor was based on the line heat-source method, and it can be applied to determine the thermal conductivities of porous mediums at different depths. The application setup was also introduced in this study.
