SPECIFICATION

Introduction: The rod is manufactured from brass and coated with a heat-resistant matte black paint, which provides a consistent emissivity close to unity. It is mounted horizontally with support at both ends positioned to avoid the influence of adjacent surfaces. It is heated by an electric heating element, which operates at low voltage for increased operator safety and is protected by a thermostat to prevent damage from overheating. Eight thermocouples are attached to the surface of the rod at equal intervals of 50mm, giving an overall instrumented length of 350mm.

 


Specifications: A small-scale accessory designed to demonstrate the temperature profiles and heat transfer characteristics surroundings. for an extended surface when heat flows along the rod by conduction and heat is lost along the rod by combined convection and radiation to the.The extended surface comprises a 10mmdiameter long solid brass rod mounted horizontally and heated at one end with a 20W, 24V DC heater. Eight thermocouples mounted at 50mm intervals along the rod provide the temperature distribution.PID controller allowing for a rapid heat temperature set-point achievement and controlled within 0.1°C.The temperature of the ambient air is measured by an independent thermocouple.The accessory is mounted on a PVC baseplate, which is designed to sit on and connect to the Heat Transfer Service Unit without the need for tools. A comprehensive instruction manual is included.
