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
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.
