program controller
Japanese: プログラムコントローラー
A controller that automatically executes firing programs. Essential for stable temperature control.
Learn More
A program controller is a device that pre-programs the temperature profile of an electric furnace and controls it automatically. By setting the target temperature, ramp rate, and hold time for each step, complex firing schedules can be executed unattended.
Many program controllers can store multiple programs (program numbers), allowing you to select the appropriate program for specific applications, such as fusing, slumping, or controlled cooling. By understanding the relationship between the setpoint and the actual furnace temperature, and by recording trends with a data logger to compare them with the firing results, you can improve the accuracy of your programs.
Related Concepts
A firing profile is composed of a combination of steps (step), target temperature (target-temperature-s), ramp time (ramp-time-t), and hold time (hold-time-h). Designing the profile in conjunction with the four-zone concept provides a systematic approach.
