Product Details

UL101 Electrical Inspector Description：

Product Manual

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.

Benefits：

Ease-of-use

Simply adjust the sensitivity on the UL101 Electrical Inspector's handheld receiver to pinpoint the leak; scan areas from up to 300 feet away with the PowerBeam 300 parabolic accessory.

Sensitivity

Our UL101 Electrical Inspector 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.

No calibration needed

Acoustic ultrasound is used for indication and location, not leak measurement. Our leak detectors are ruggedized for use in the most caustic of environments, including power plants.

Applications：

Electrical Inspection(Power Transmission and Substations,Electric Panels,MMCs, etc)

Key Features：

Fixed Frequency

Double the sensitivity of other parabolic dishes

Easily adjustable sensitivity and gain

Converts ultrasound to easily recognizable audible sounds

Standard 9-Volt Battery for UL101 Receiver

Two AAA Batteries for PowerBeam 300 (powers laser pointer)

"Rifle Site" to pinpoint when outdoors

Laser to pinpoint when indoors

Inspect sealed panels without opening or using an expensive window

Identify arcing and tracking potential as a safety precaution before using infrared
