SL377 Thermal Laboratory Equipment Vocational Training Equipment Convection and Radiation Heat Transfer Training Equipment

• 1. Description
  Under real conditions, the heat transport between two objects is normally substance-bound, ie convection and/or heat conduction, and not substance-bound, ie radiation, at the same time. Determining the individual heat quantities of one type of transfer is difficult .
  
  The SL 377 trainer enables users to match the individual heat quantities to the corresponding type of transfer. The core element is a heated metal cylinder located at the centre of the pressure vessel. The surface temperature of the heated metal cylinder is controlled. The surface temperature of the metal cylinder and the wall temperature of the pressure vessel.
  
  The pressure vessel can be put under vacuum or positive gauge pressure. In the vacuum, heat is transported primarily by radiation. If the vessel is filled with gas and is under positive gauge pressure, heat is also transferred by convection. It is possible to compare The heat transfer in different gases. In addition to air, nitrogen, helium, carbon dioxide or other gases are also suitable.
  
  Heat transport by conduction is largely suppressed by adequately suspending the metal cylinder.
  
  2, can be realised with compressed air. Two pressure sensors with suitable measuring ranges are available for the pressure measurement: a Pirani sensor measures the negative Pressure while a piezo-resistive sensor measures the positive pressure.
  
  The measured values can be read on digital displays.
