In addition to the best electric heater and temperature sensor designs, precise thermal control can only be accomplished with electronic temperature controllers having control algorithms optimized for a specific application. Watlow's family of single and multi-loop controllers and limits complete the thermal loop. Thousands of semiconductor applications have given Watlow the expertise to select the best control solution for applications.
Our controllers not only provide precision closed loop control, but also provide a means to network the thermal aspects of the semiconductor process. Networking gives the process engineers a means to predict system performance changes and take corrective action before a significant drop in wafer yields can occur. Watlow temperature controllers support a process LAN through DeviceNet™ over CAN, Ethernet, Modbus™ or RS-235.
