Seebeck Coefficient/ Electric Resistance Measuring System

The Thermal power, thermoelectric power, or Seebeck coefficient of a material measures the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material. The thermal power has units of (V/K). In recent years much interest has been shown in various methods of direct conversion of heat into electricity. Waste heat from hot engines and combustion systems could save billions of dollars if it could be captured and converted into electricity via thermoelectric devices. For this challenging application LINSEIS has developed a characteristic evaluating...

To enable advanced research in Thermoelectrics, LINSEIS offers a complete range of instruments for this demanding task. The instruments available involve Seebeck and Electric Resistivity - LSR, Thermal The LSR - 3 can simultaneous measure both Seebeck coeffifi cient and Diffusivity and Thermal Conductivity - LFA, Thermal Expansion and electric resistance (Resistivity). Density – Dilatometer, Specific Heat – DSC. • Prism and cylindrical samples with a length between 6 to 22mm can be analyzed S: Seebeck Coefficient; [S] = μV/K I: Electrical Conductivity; [s] = 1/Ωm K: Thermal Conductivity;...

A sample of cylindrical or prism shape is vertically positioned between two electrodes. The lower electrode block contains a heater, whilst the entire measuring arrangement is located in a furnace. The furnace surrounding the measuring arrangement heats the sample to a specififi ed temperature. At this temperature the secondary heater in the lower electrode block creates a set temperature gradient. Two contacting thermocouples then measure the temperature gradient T1 and 12. A unique thermocouple contact mechanism permits highest accuracy measurements of the electromotive force dE at one...
