UL101

The UL101
Basic Kit

The CTRL UL101 Basic Kit includes attachments for airborne ultrasound applications including leak detection (any type of gas), vacuum leak detection, electrical inspection, and steam leak detection. Additionally, the kit includes a single 3-inch solid probe for diagnosing steam traps and valves by detecting internal by-pass leaks

The Benefits

Ease-of-Use
Sensitivity
Directionality
Costs
No Calibration
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. 

No Calibration

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

Key Features

Fixed Frequency

Easily adjustable sensitivity and gain

Lightweight, one-handed operation

High Sensitivity to all turbulent flow air, gas, or vacuum leaks

Converts ultrasound to easily recognizable audible sounds

Standard 9-Volt Battery means no waiting to recharge

Applications

Leak Detection

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.

Electrical Inspection

Airborne ultrasound can be used to detect various electrical faults; including corona discharge, tracking, and arcing.

Valve & Steam Traps

Effective use of the UL101 for ultrasound detection on valves can reduce and even eliminate unnecessary overhaul costs, resources, and time.

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.
