The heat transfer insulating powder trainer unit consists of two thin wall concentric copper spheres. The inner sphere houses the heating coil. Heating coil is made up of nichrome wire wound on mica sheet. The insulating powder packed between two shells. Power supply to the heater is given through a dimmer stat & is measured by voltmeter & an ammeter. Temperature can be measured with the help of thermocouples. Four thermocouple are embedded on inner sphere and six thermocouples are embedded on outer sphere. The entire ten-temperature indicator, these reading enable of insulating powder.

The experimental unit is equipped with temperature sensors inside and outside of the concentric copper spheres. The microprocessor-based instrumentation is well protected in the housing. The software consists of a software for system operation and for data acquisition and an educational software.

Ltekonline are the manufacturers of Computerized Thermal Conductivity of Powder used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Heat and Mass Transfer Lab Equipment for Engineering Teaching Lab in Universities
