Sensors & Controls

Sensors and Controls

Driven equipment is generally powered by electric motors. Most motors require some type of controller. When a drive operates at a constant speed, the controller could be a simple motor starter. Often times, controllers will also include auxiliary devices (fused switches, circuit breakers, contactors, or relays) and remote components (push-buttons, selector switches, indicator lights, and variety of displays and sensors).

Adjustable speed drives power systems where motor speed must be changed to adjust to different operating conditions. Both motor starters and adjustable speed drives sometimes operate in coordination with one or more other starters or drives; and in some cases, they operate in conjunction with PLCs (Programmable Logic Controllers) and computers. To learn more, visit the about adjustable speed drives page.
