The ET130 natural radiation and convection study bench consists of two superimposed enclosures: one heated electrically and regulated, the other cooled by a water exchanger; the whole working under vacuum or at atmospheric pressure. The outlet of the exchanger is equipped with a thermocouple. Experimental devices make it possible to position two circular bodies (black and gray) in one or the other of these enclosures. The temperature of each body is measured by an associated thermocouple (bolometer). A vacuum pump is integrated into the bench.

Experimental possibilities

This bench allows to :

• Record the absorption and emission curves of the two bodies under vacuum.
• Record the heating and cooling curves of the two bodies.
• Determine the coefficient of emissivity or absorptivity, the constant of Stefan Boltzmann.
• Determine the conductance per unit area.
• Calculate the exchanges by radiation and convection.

Technical specifications :
• Temperature of the regulated chamber between 0 and 299 ° C
• Digital display of sensor and exchanger temperatures
• Max. Vacuum rate : - 0.95 bar
• Measuring range of the vacuum gauge 0 to - 1 bar
• Analog outputs: Sensor temperature, derived from sensor temperature.
• Water exchanger: network water supply
