Watlow Auto-Tuning PID Controllers

Watlow's recently launched controllers, include the new SERIES SD temperature controllers and the DIN-A-MITE^®

family of power controllers. This updated section of the web site provides information on Watlow's growing selection of connectivity products including the SERIES PD, D8 and N7 controllers as well as the EM and CDN gateways.

Auto-Tuning PID Controllers

Single-Loop Available in 1/32, 1/16, 1/8 and 1/4 DIN sizes, agency approved Watlow single-loop, auto-tuning temperature controllers automatically set PID control parameters for optimum system performance. Manual settings also permit on-off, P, PI or PID control modes. All Watlow auto-tuning controllers are designed and manufactured to withstand harsh industrial environments and come with a three-year warranty for Control Confidence®.
