The cold section is of identical dimensions to the hot end and is water-cooled. Both the heated and cooled ends are each fitted with three thermo couples at 15mm intervals to measure the temperature gradients along the bars.
A small-scale accessory that allows experimental investigation of linear heat conduction and the measurement of the thermal conductivity of various solid conductors and insulators.
The hot end uses a nominal 65W heater (operating at 240v maximum), which is fitted with a high temperature limit switch. The power supplied to the heater is controlled and measured by the Heat Transfer Service Unit .
An insulated, 25mm diameter brass heated section and cooling section that may be either clamped together, or assembled with one of four insulated intermediate sections or test specimens between the interfaces.
The heating section, cooling section and one of the intermediate sections are fitted with thermocouples (eight in total) evenly spread along the length of the assembled conduction path.
A small-scale accessory designed to introduce students to the principles of linear heat conduction, and to enable the thermal conductivity of various solid conductors and insulators to be measured.
Includes a water pressure regulator, an electronic proportioning solenoid valve to control the cooling water flow rate and a water flow meter.
Comprises a heating section, cooling section plus four intermediate section conductor samples and two insulator samples.
All sections are insulated to minimize errors due to heat loss.
Includes a water pressure regulator and a manual flow control valve.
Heater power variable up to 60 Watts.
Water flow rate variable up to 1.5l/min.
Heating and cooling sections, 25mm diameter.
A comprehensive instruction manual is supplied.
The accessory is mounted on a PVC baseplate, which is designed to stand on the bench top and connect to the Heat Transfer Service Unit without the need for tools.
