Rancang Bangun Alat Uji Konduktivitas Thermal Material

Abstract

Heat transfer is very important in the field of engineering and life aspects. Many household appliances are made using the principles of heat transfer, such as: cookware, oven, iron, car engine, exhaust, air conditioner, etc.This test aims to design a thermal conductivity test instrument on a heat flow approach in steady state (Steady) one dimension using a nickel wire as a heat source using electricity, while the temperature sensor used is a K type thermocouple that is linear to temperature changes. The electric voltage converted from the thermocouple is converted digitally by the Autonic brand converter to obtain the value of temperature by the test equipment. The test results showed the test material having conductivity 0,62774 w / moK. The difference from general building material data with 1.12 w / moKthermal conductivity is different due to materials of stone block maker with different constituent elements (different manufacturers)
