Furnace Controllers

Furnace controllers are used to control temperature, heat delivery, and other variables in industrial furnaces. They control the burner flame, air mixture and trim to maintain and optimize furnace performance. Furnace controllers receive inputs from thermocouples and sensors, and can be integrated with other industrial control systems. Some products are designed to calculate levels of carbon dioxide or methane. Others are used to monitor ammonia additions. Choices for furnace controller functionality include: rate indication and control, data logging, and totalizing. The user interface may consist of a digital front panel or analog components such as knobs and switches. Computer-programmable, web-enabled, and network-ready furnace controllers are commonly available. A furnace controller with digital controls may include human machine interface (HMI) software or provide supervisory data acquisition and control (SCADA) functionality.
