[1]   Click to Enlarge THERMAL CONDUCTIVITY OF METAL ROD Determines thermal conductivity of metal rod. a copper bar, heated at one end, heat sink at other end, teat section of bar is properly insulated & thermocouples are attached for temperature. Heat conducted through the section of bar is measured by heat collection in water cooled heat sink.A panel compresing of controls and measurement is provided. See Enlarge Click to Enlarge THERMAL CONDUCTIVITY OF INSULATING POWDER Determines thermal conductivity of insulating powder by sphere in sphere method. A copper sphere in which a mica heater is fitted. the sphere is surrounded by another bigger sphere and between the two sphere,the test insulating powder is filled. Heat of the heater radically flows outwards in all directions through powder. temp. Across the powder are measured. by knowing input to the heater conductivity of powder can be dtermined. See Enlarge Click to Enlarge THERMAL CONDUCTIVITY OF LIQUID An electrical heater sandwitched between aluminum plates. heat loss from hot plate is prevented by using two guard heaters and heat of hot plate is made to flow through specimen. cold plate on opposite face of liquid removes heat from liquid by circulation of water. Input to heaters can varied & measured. Digital temp Indicator to measure temperature. See Enlarge Click to Enlarge THERMAL CONDUCTIVITY OF INSULATING SLABS BY 10260 GUARDED HOT PLATE METHOD To determine thermal conductivity of specimen,main heater and radial heater sandwitched between copper plates. Specimen in the form of slabs of equal thickness are placed on either sides of heaters and cooling plates. other side of specimen water is circulated. Radial guard heaters ensures all heat of main heater passes axially through the specimen, collected by cooling plates. By knowing the themp. And heat input, thermal conductivity of specimen can be calculated. See Enlarge [1] Go to Top
