Convection And Radiation

Electrically heated metal cylinder in the pressure vessel as experimental vessel
Temperature-controlled heating element
Heat transfer between heating element and vessel wall by convection and radiation
Vacuum generation with rotary vane pump
Instrumentation: 1 temperature sensor at the vessel wall, 1 power sensor at the heating element, 1 Pirani pressure sensor, 1 piezo-resistive pressure sensor
Operation with various gases possible
Experiments in vacuum or at a slight positive gauge pressure.
