Company Divisions

Control Concepts' Speed Switch Division offers UL approved zero speed switch models for use in many different industrial applications including conveyors, blowers, motors, drums, rotary feeders, bucket elevators, fans, airlocks, screening machines, crushers, dryers, burners and rotary kilns. Operating ranges are between 0.1 and 2,000 RPM. Control Concepts, Inc. zero speed switches include electro mechanical devices that need no electrical input power to operate as well as electronic devices. All of their zero speed switches require no periodic calibration or field maintenance and can act as a PLC input.

Control Concepts' AcoustiClean™ Division manufactures sonic horns that are designed to produce and amplify low frequency sound vibrations at high volume for the removal of particle build-up. Some common applications include: baghouses, bins, silos, hoppers, SCRs, boilers and electrostatic precipitators.

Control Concepts' Counting Devices Division specializes in the manufacture of mechanical “diff” counters. Their counters have been used by hospital, medical and scientific laboratories, as well as, cafeterias and transit operators across the world for over 70 years. With little practice these cell counters can be stroked by “touch” much like a keyboard. Used in this way the operator’s eyes are not diverted from the microscope, table or counter top and counts are completed quickly and accurately.

Control Concepts' Airsweep Division specializes in the manufacture, design and sales of bin discharge systems. These systems provide a proven way to start and maintain flow of "tough" bulk granular materials.

Client Testimonials

“At Taunton, we earned our reputation for engineering excellence. To protect that reputation, we only use controls we have utmost confidence in. We specify Control Concepts Zero Speed Switches.”
- Taunton Engineering

“Meyer incorporated the Control Concepts Switch into its design some 20 years ago. It withstood the test of time in some very severe service environments. And, given the high level of support we receive from the Control Concepts people we expect our association to continue.”
- Wm. W. Meyer & Sons, Inc. .

AcoustiClean Sonic Horns:

High powered acoustic cleaning horns designed to prevent costly particle build-up. AcoustiClean sonic horns produce high energy, low frequency sound waves. This is accomplished by forcing compressed air through a sound generator causing a titanium diaphragm to vibrate. This vibration creates a series of sound waves. The sound waves enter the vessel resonating the particles loose from the surfaces on which they have settled.
