CTRL Acoustic Ultrasound Solutions

Electrical Systems

Airborne and structured-based (A&SB) ultrasound can be used to detect various electrical faults; including corona discharge, tracking, and arcing. The PowerBeam 300 parabolic accessory allows the technician to locate sources of ultrasound with pinpoint accuracy from distances up to 300 feet away. Additionally, the InCTRL platform and InCTRL mobile app can be used to record samples, store testing history, and communicate faults through a management chain. InCTRL's FFT spectral analysis feature can be used to diagnose recorded samples for electrical failures.


CTRL’s airborne ultrasound solutions can quickly and effectively locate hydraulic fluid system leaks, even during peak operation. Technicians do not have to feel around operating machinery or failed parts with their hands to find leaks, or spray down components with soap and water solution looking for bubbles to find leaks. Ultrasound leak detection is not hindered by facility operation noise, and therefore involves less guess work in leak isolation.

Our integrated ultrasound listening device, the UL101 Leak Detector, will allow you to focus more time on production and less on quality control inspections, warranty rework, and infield repairs. Additional uses of the UL101 Leak Detector include using the provided solid probe attachment to listen for ultrasound. By pressing the tip of the solid probe (attached to the UL101 receiver) against a valve, you can easily hear the valve functioning and determine its operating condition, such as a leak.

Leak Detection

Airborne and structure-based (A&SB) ultrasound detection can be used to easily locate leaks within a noisy environment. CTRL Systems has designed an easy-to-use device that is more sensitive than any other ultrasound detector in the world. With the UL101 Leak Detector and our conditioned based monitoring technology, you can detect leaks from up to 150 feet away and pinpoint their exact location in mere seconds. The UL101 Leak Detector is not affected by loud industrial environments and can be used in windy conditions. It can be used to locate any type of turbulent compressed gas or vacuum leak. Applications include: compressed air energy swings (reduce compressor usage by 20-30%!), vacuum leak detection, HVAC leak detection, dry sprinkler inspection, steam system inspection, cabin testing, and many more!

Mechanical Lubrication

Precision lubrication is based on using an acoustic ultrasound detector to see if the bearing needs to be lubricated, and how much lubricant it needs to operate as a reliable asset. CTRL uses airborne & structure-borne ultrasound (AB&S) technology to allow users of our UL101 ultrasound listening devices to detect frequencies over the human audition threshold. Friction caused by the bearings, regardless of type, size, speed, or weight, will generate detectable high frequency acoustic energy.

By controlling the lubrication frequencies using the UL101 Troubleshooter and InCTRL platform, you can considerably lower the index of bearing failures in your systems.This type of program can maintain the assets of the plant in optimal operating conditions, and at the same time reduce your operation and maintenance costs. CTRL solutions will increment the availability time of the process and diminish risks to your personnel and plant assets.

Valve and Steam

As fluid passes or flows around an obstruction, downstream turbulence is generated, resulting in an auditory signature. The differential changes in the signature (i.e. amplitude) is considered leak-by. Effective use of the UL101 Troubleshooter for ultrasound reliability on valves can reduce and even eliminate unnecessary overhaul costs, resources, and time.
