UL101 Electrical Inspector

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.

Ease-of-Use

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. 

Sensitivity

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. 

Directionality

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. 

Costs

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.
