DESCRIPTION
Technical Description
This experimental unit enables experiments to be performed on steady-state heat conduction in non-metallic materials such as polystyrene, PMMA, cork or plaster in accordance with DIN 52612. Specimen sheets are placed between a heater plate and a water-cooled plate. A clamping device ensures that the clamping pressure and thermal contact are reproducible.
A special sensor measures the heat flux. Electronic controllers keep the temperatures of the heater plate and cooling plate constant within close limits.
The measured values are transmitted directly to a PC via USB. The data acquisition software is included.
Learning Objectives / Experiments
- determination of the thermal conductivity k of different materials
- determination of the thermal resistance
- thermal conductivity k of several specimens connected in series (up to a thickness of 50mm)
