Temperature & Process Controllers

PID and limit controllers, process controllers, and SCR power controllers for precise heat and process control.

Anderson-Bolds supplies temperature and process controllers from Watlow, Fenwal, and Novus — PID process controllers, FM-approved limit controllers, and SCR power controllers. We can pair a controller with the matching Watlow heater and sensor so the loop is sized and tuned together.

Brands in Temperature & Process Controllers

Temperature & Process Controllers — questions buyers ask

Do I need a separate limit controller?

For most heating systems, yes — a redundant high-limit controller with its own sensor protects against runaway if the primary control loop fails, and it's often required by code or insurers.
