The CTAC-2 “Cone of Silence” from Coiltek

At Coiltek we try to anticipate any issues that our customers may have and create a solution. One such issue when using an ultrasonic loop control system is off-axis ultrasonic interference. This interference can be caused by things such as nearby blow-off hoses and can cause a unit to behave in strange ways.

Luckily we have devised a simple solution to issues of ultrasonic interference: The CTAC-2, nicknamed the “Cone of Silence”, the CTAC-2 is a cast aluminum cone lined with acoustic foam, which slides easily over the boom of your existing unit and absorbs any off-axis interference.

If you have any questions or comments on the CTAC-2 or any of our high quality no-touch loop control systems or accessories, please don’t hesitate to contact us.

“Free Loop” Controls

At Coiltek our loop controls are designed as no-touch controls for free loops. A free loop is an unfettered drop off of coil stock – slack in the line – before it enters into a process or is rewound.

The advantages of no-touch loop control systems are many, and have been discussed at some length in previous posts, but one of the major advantages is for use with non-conductive stock, such as extruded rubber or plastic medical tubing.

Our sensitive non-contacting, ultrasonic loop controls can be used on everything from wide stocks to very thin stocks. Coiltek loop controls can also be used with a variety of materials because, in addition to being very sensitive, our loop controls are adaptable.

For use with stocks that move either horizontally or vertically, we created the Hammerhead Accessory and the CS-5140 to ensure the stock is always within range. Additionally, each Coiltek loop control is essentially a custom build. We have several lines of loop controls, including a low-cost ultrasonic control, a stand-less line of loop controls, and our standard product line, the CS-5000. Each CS-5000 is fully customizable, as the customer chooses the height of the stand (either 15″, 54″, 72″, or 84″) and boom length (choose from 9 lengths between 11″ and 48″). This flexibility allows our loop controls to work with everything from tables to pits and everywhere in between. Since our no-touch ultrasonic loop controls rely on sound waves, not electrical contact or photo-technology, reflective stocks and non-metallic stocks are no problem.

A brief history of ultrasonic loop controls

In the late 1970s two men had the same great idea at the same time. One of those men was Hall Cary, the founder of Coil Technology, Inc.

As an acoustical engineer, Hall had already founded the Cary Corporation, which specialized in manufacturing sound isolating enclosures for press lines and other equipment. Well-versed in the physics of sound, he thought that perhaps sound waves could be harnessed for use in manufacturing processes.

The result of this line of inquiry was the original Coiltek ultrasonic loop control. Using an ultrasonic element to transmit and receive sound waves, the device could accurately gauge distance. By coupling this ability with the ability to create a variable 0-10 VDC output based on the distance of an object from the element, the ultrasonic loop control was born.

To learn more about why non-contacting or no-touch loop controls are such an important innovation and the advantages of a Coiltek loop control over the competition, feel free to contact us. For a full list of our current products, please visit our products page or check out our brochures.

Non-Contact Loop Controls

Our Coiltek loop controls are non-contact loop controls. While most manufacturers of ultrasonic loop control systems have only one line of no-touch loop controls which use out-dated technology, we have two distinct lines of completely upgraded ultrasonic loop control systems.

The new Coiltek CS-5000 V2 and CS-6200 lines of non-contacting loop control systems are powerful and reliable. Our updated technology allows for on-board storage of preset programs, USB connected remote programming via computer, and instantaneous manual calibration.

At Coiltek we are always looking for new applications. With this in mind, we are creating a model of the low-cost, non-contacting CS-6200 line, the CS-6202, for use specifically within plastic tubing manufacturing.
