Abstract: A non-contact measuring device for electrical resistivity has been designed, which is based on electromagnetic induction principle. Using the device, the electrical resistivity of metals can be monitored during transition from liquid to solid state, which shows that the device is suitable for analysing the structure transition of metals and alloys during the cooling process.The design principle and construction of the device are detailedly described in this paper. The change of electrical resistivity of pure Zn and pure Sb, and hypereutectic Zn-70wt.%Sb alloy during cooling was measured by the device. The experiment results show that the device preforms well.
