Abstract: This paper introduces a high accuracy temperature control system that is consisted by microcomputer, and in which the heating component used is appliced≤1650℃. This system may used in some areas as heat treation, physical determination and high temperature
laboratory ,etc. It was proved that it is a high accuracy temperature control system with exact
temperature control (accuracy≤±1℃), stable function, easily operation and extensive applicability, so these have important meaning and widespread applied value to decrease comsumption of energy and prolong available life of the furnace.
Keywords: computer； high accuracy temperature control
