Abstract

During making this research. it is study about amplifier and heat transfer in more details. Heat transfer is divided into three categories which are conduction. convection and radiation. There also needs to know about hardware because for easily choose while doing experiment to get the suitable data. And also about thermocouple, the first thing need to know is the temperature of pipe or ducting need to measure. Then that can choose a suitable thermocouple with temperature. The table of thermocouple is used as a reference in measuring temperature. In order making interface. the main device needed is PIC 16F877 and MAX232. In this research also. the measuring amplifier was developed. It is used to increase the potential voltage of thermocouple from m V level to the level between 0 and 5V. This is required to reduce the quantization error during the sampling process using internal analogue to digital converter installed in PIC 16F877 before transfer the data to a local PC.
