A muffle furnace separates the workpiece from the heat source by means of a “muffle”, a removable and sometimes adjustable component used to aid temperature uniformity.
The furnaces may be used for heat treatment of small components and laboratory testing of materials, and many other applications where uniformity and accuracy of temperature control is required.
In this example, the Eurotherm EPC2000 device provides high accuracy temperature control, using the Eurotherm EPack™ SCR Power controller to manage the non-linear heating characteristics of the loads. A Pro-face GP4100 touchscreen is used as the primary operator interface.
This provides a high performance furnace control system with fast responding enhanced Eurotherm PID control with minimal overshoot. The touchscreen panel is easy-to-use and customize, and the furnace can be connected using Ethernet communication or via a WiFi router to data loggers or personal computers.
