Microcomputer-based programmable controller of temperature

The microcomputer-based programmable controller of temperature has been researched and manufactured to perform automatic control of the furnace temperature according to the given temperature patterns stored in memory of the microcomputer. The patterns can simulate any curves or functions, and can be called for execution or rewritten if necessary. The 16 light digital tubs mounted on the controller can display the programming process and running process in real time. The nonlinear correction and PID control law have been accepted. This controller gives a good tool for research and production in view of temperature control of furnace.
