Control Concepts, Inc. is a manufacturing company located in Northeast Connecticut in the United States. For over 50 years Control Concepts Inc. has specialized in manufacturing shaft driven, speed switches. Over the years we have grown and have added three additional product lines. Our products are used in the Power Generation, Mining, Agriculture, and Medical industries. \r\n\r\nOur Speed Switch Division offers many models for use in different applications. Operating ranges are between 0.1 and 2,000 RPM. CCI speed switches are electromechanical devices that need no electrical input power to operate and require no periodic calibration or field maintenance. \r\n\r\nOur AcoustiClean Division manufactures acoustic horns that are designed to produce and amplify low-frequency sound vibrations at high volume for removal of particulate build-up. Some common AcoustiClean applications are baghouses, bins and silos, hoppers and electrostatic precipitators.\r\n\r\nThe Counting Devices Division specializes in the manufacture of "Diff Counters". Our Counters have been used by hospitals, medical and scientific laboratories the world over for some 50 years. With little practice, these cell counters can be stroked by #touch', much like a typewriter. Used so, the operator's eyes are not diverted from the microscope and counts are completed quickly and accurately.
