Thermal Conductivity of Building Materials WL 376

Thermal Conductivity of Building Materials

Type: WL 376
Name: Thermal Conductivity of Building Materials

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)

Features

* Heat conduction in non-metallic materials1
