Extech controllers now offer Fuzzy Logic enhanced PID and a Soft-Start feature that protects heaters from cold-starts. PID plus Fuzzy Logic tackles even the most demanding applications, eliminating over-shoot, unwanted process fluctuations, and drift. The Soft Start feature is ideally suited for processes, such as those employed in the Thermo-Plastics industry, where careful, exact, and slow heating of product is required.
