Convection And Radiation

Convection And Radiation .

Specification Of Convection And Radiation

• Heat transfer between heating element and vessel wall by convection and radiation
• Operation with various gases possible
• Experiments in vacuum or at a slight positive gauge pressure
• Electrically heated metal cylinder in the pressure vessel as experimental vessel
• Temperature-controlled heating element
• 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
