In heat treating operations, the temperature controller must be able to compensate to keep the furnace at the optimal temperature regardless of the load size. Some processes involve just a heating cycle or just a cryogenic cooling cycle, but many involve both.

Proportional-integral-derivative control methods — more commonly known as PID control — have been used in industrial applications for as long as anybody can remember. 

Like many, our company has a display of old equipment related to our products. In our case, it is a collection of temperature controllers that date back to 1912.

All three models in the Pro Series — the Pro-4, Pro-8 and Pro-16 — provide two PID sets.

Model RE92 is reliable for the most demanding industrial control applications.

When deciding on a temperature control scheme for a process, options include a PLC or stand-alone temperature controllers. Learn about the pros and cons of each technology in process applications.
