Bulk Pro Systems Conveyors Speed Switches are process instruments that are designed to enunciate an alarm when the rotation stops or slows. Bulk Pro Systems carries a complete line of speed switches. They come standard with either a discreet output or 4-20mA linear output or both. We have proximity type speed pick-ups or the most innovative design on the market – magnetically coupled. All of Bulk Pro Systems Conveyor Switches are built for the most rugged industrial applications. These speed switches are currently being used on conveyors all over the world. Choosing the most appropriate speed sensing technology is important. Bulk Pro Systems can recommend the right kind of technology based on the material and the application.
