Thermal Conductivity Of Insulating Powder

Thermal Conductivity Of Insulating Powder

Thermal Conductivity Of Insulating Powder

• This apparatus is designed to determine the thermal conductivity of insulating powder. The apparatus consists of two thin walled concentric copper spheres. Inner sphere houses Ni-chrome Wire heater
• Insulating powder is filled between the two spheres
• Heat flows radially outwards. Temperature sensors at proper positions are fitted to measure surface temperatures of spheres
• Heat input to the heater is given through a variac and measured by Digital Voltmeter & Digital Ammeter. By varying the heat input rates, data can be obtained

Technical Specifications: 

• Inner Sphere: Dia: 100 mm
• Outer Sphere: Dia: 200 mm
• Heater: Nichrome Wire
• Digital Voltmeter: 0-300 Volt
• Digital Ammeter: 0-2 Amp
• Variac: 0-230 V, 2 Amp
• Digital Temp. Indicator: 0-199O C, with multi-channel switch
