UL101

LEAK DETECTOR

000036 Standard Model
000038 Intrinsically Safe Model

The UL101 Leak Detector quickly locates the ultrasound waves produced by compressed gas and vacuum leaks. Simply aim the leak detector in the direction of the piping and adjust the sensitivity to pinpoint the location of any leak with turbulent flow. The UL101 has the best signal-to-noise ratio and highest sensitivity in the market. Leaks sound like rushing air in the operator's head set, and the gain can be minimized to eliminate all or most ultrasonic "white noise" for an operator-friendly user experience. 

Benefits of UL101 Acoustic Ultrasound Listening Devices

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. 

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. 

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

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. 

 
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. 

Applications

Leak Detection (Pressure & Vacuum)
Electrical Inspection
Valves & Steam Traps

How the CTRL UL101 Leak Detector 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.
