Dependable detection begins with a Watlow controller. Watlow’s popular line of EZ-Zone PM controllers can be installed easily for controlled loop feedback. The popular line of Watlow EZ Zone controllers are available as top-performing PID controls, over/under limit controllers or integrated devices.

An optional high amperage power controller can also be included in the package, which requires less panel space and is simple to use. PID stands for proportional-integral-derivative and is a common standard of process control.

Integrated PID temperature controllers and limit controllers are associated with lower ownership, and installation costs installers also appreciate the reductions in wiring time and termination complexity that streamlined control packages can offer.
