The UL101 Electrical
Inspector
The UL101 Electrical Inspector utilizes airborne attachments to safely inspect sealed electrical panels and substations. The UL101 Electrical Inspector allows for early, long-distance detection of arcing, corona discharge, and tracking. Save time and money by reducing transmission/distribution loss and outages. The parabolic accessory (PowerBeam 300) can accurately pinpoint sources of ultrasound within 1 degree off target from up to 300 feet (91.44 meters) away.
The Benefits
Simply adjust the sensitivity on the UL101 Leak Detector’s handheld receiver to pinpoint the leak; scan areas from up to 300 feet away with the PowerBeam 300 parabolic accessory.
Our UL101 Leak Detectors can find leaks faster and more accurately. Your systems can now run at normal and even improved vacuum levels to improve power turbine efficiency.
Ultrasound travels in linear paths and doesn’t tend to travel around corners or reflect. Using CTRL’s acoustic ultrasound listening products, leaks are not easily masked.
The cost of a high end ultrasound detector is 3 to 5 times less than the cost of a helium leak detection system. CTRL’s UL101 products are priced competitively compared to industry leaders, require less training, and are faster to use.
Key Features
Inspections performed at a safe distance
Ability to inspect sealed panels
Lightweight, accurate, easy to use
Identify arcing and tracking potential as a safety precaution before using infrared
Inspect sealed panels without opening or using an expensive window
How It Works
Using ultrasound detectors for leak detection is a growing industry standard. Acoustic ultrasound leak detection is recommended by many, such as the U.S. Department of Energy, as the best method for detecting the location of leaks in order to minimize energy waste and improve plant efficiency.
The CTRL UL101 Leak Detector converts the ultrasound (40 kHz +/- 1 kHz) down into the audible range and outputs to a headset. All other frequencies are filtered, so that even the smallest air/gas, vacuum, or refrigerant leak can be detected and pinpointed in a noisy plant environment.
