Watlow Controller / Watlow EZ-Zone

watlow ez zoneDependable detection begins with a Watlow controller. Watlow’s popular line of EZ-Zone PM controllers can be installed easily for controlled loop feedback. These popular Watlow EZ-Zone controllers are available as top-performing PID models, 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.

Watlow single-loop controllers with microprocessor technology can provide extensive communication capabilities and the latest in network connectivity that commercial control systems require. Using multifunctional, modular devices allows owners to adapt to the dynamic workplace with nominal time and financial investment. Control loop and limit additions can be incorporated individually. A full menu of Watlow features includes standard bus communications and adaptive control.
