Computerized Thermal Conductivity of Powder
Product Code : EL-HAMTLE-10760
Quick Answer:
The Computerized Thermal Conductivity of Powder trainer measures heat conduction through insulating powder packed between two thin-walled concentric copper spheres, with a nichrome-wire heating coil wound on mica sheet inside the inner sphere. Four thermocouples on the inner sphere and six on the outer sphere track the temperature gradient across the powder layer, with heater power supplied through a dimmer stat and measured by a voltmeter and ammeter, and readings logged via the microprocessor-based instrumentation and PC software for calculating the powder's thermal conductivity at different temperatures.
Overview:
The heat transfer insulating powder trainer unit consists of two thin wall concentric copper spheres; the inner sphere houses the heating coil, and the experimental unit is equipped with temperature sensors inside and outside of the concentric copper spheres. The heating coil is made up of nichrome wire wound on mica sheet, and the insulating powder is packed between two shells. Power supply to the heater is given through a dimmer stat & is measured by voltmeter & an ammeter, and temperature can be measured with the help of thermocouples: four thermocouples are embedded on the inner sphere and six thermocouples are embedded on the outer sphere. The entire ten-temperature indicator, these reading enable of insulating powder. The microprocessor-based instrumentation is well protected in the housing, and the software consists of a software for system operation and for data acquisition and an educational software.
