Ultrasonic Leak Detectors

A reliable source for Ultrasonic Leak Detectors information and leading Ultrasonic Leak Detectors Companies & Manufacturers.

Ultrasonic leak detectors produce high-frequency, powerful pulses that travel through materials as waves. When there is a surface defect or interruption, some energy is reflected back instead of traveling through materials. To find a leak, ultrasonic leak detection locates high-frequency sounds of leaking pressurized gas. If the leak is turbulent, the leak detector only needs to discover compressed air. Read More…

Ultrasonic Leak Detectors Ultrasonic leak detectors are used for large gas leaks. Because gas leaks are often noisy, the ultrasonic technology converts the high frequency leak sound to a lower range where the hissing of the leak can be heard through a set of headphones and traced to the source. Ultrasonic leak detectors are somewhat new to the industry.

An ultrasonic detector is effective if it converts high-frequency leak sounds to lower ranges – a process called heterodyning. Hissing leaks can be located by listening through a pair of headphones. Every turbulent gas will produce ultrasound when it leaks. Ultrasonic detectors can even pick up air rushing into a system while being vacuumed.

Ultrasonic Maintenance Examples

Ultrasonic maintenance works for lots of equipment. Vacuum leak detection, gas leak detection, and compressed air leak detection are common applications of ultrasonic technology.

  • Inspection of complicated air and gas pipe networks: Compressed air and compressed gasses are necessary for facilities to function. An intricate network of pipelines distributes these gasses from a central point. Leaks can happen anywhere, causing expensive repairs. Ultrasonic leak detection is the quickest, most precise method for finding even the smallest leak in a system.
  • Safety enhancements: The main problem caused by compressed air leaks is efficiency loss. However, safety takes precedence when a system is leaking harmful or dangerous gases. Leaks can place staff in immediate danger, so leaks must be rapidly located and fixed.

Advantages of Ultrasonic Leak Detection

  • Reliable air and gas delivery: Leaky systems use more energy to keep the pressure at the same level. If there are enough leaks, the system won't function properly. This could lead to a chain reaction of inefficiencies in compressed gas-dependent end-use processes or the termination of those operations.
  • Improved safety: All working staff are significantly at risk from hazardous gas leaks. Ultrasonic leak detection allows companies to comply with safety standards.
  • Low maintenance costs: By spotting leaks as soon as they appear, repairs can be planned for a time that won't interfere with output. Massive failures requiring involved, and expensive repairs are minimized or completely avoided.

Drawbacks of Ultrasonic Leak Detection

Ultrasonic equipment can rarely be automated, allow users to test to a leak rate standard, provide repeatable accuracy, or offer test result management.

Ultrasonic Leak Detector

There are leak detection techniques that offer more precise and controlled leak testing. The typical ultrasonic leak detection device can only identify leaks in the 60 sscm range. The operator’s performance, environmental context, and capacity to separate sound frequency from background noise all affect the efficiency of ultrasonic leak detection. It’s harder to identify leaks when acoustical leak testing is carried out on insulated lines, underground, or through walls.
