SPECIFICATION
Introduction:
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 Nichrome Wire heater. Insulating powder is filled between the two spheres. Heat flows radically 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.
Specifications:
Inner Sphere: Dia. - 100 mm
Outer Sphere : Dia. - 200 mm
Heater: Nichrome Wire.
Control panel comprising of: Digital Voltmeter: 0-300 Volt
Digital Ammeter: 0-2 Amp.
Variac: 0-230 V, 2 Amps.
Digital 0 Temp. Indicator: 0-199.9 C, with multi-channel switch
Temperature Sensors: RTD PT-100 type. With standard make On/off switch, Mains Indicator etc.
