Ultrasonic Leak Detector

Gas leak detector safety information and other useful tips.

Many factories and installations use large compressed air systems in their operations and the efficiency of these can be affected by leaks of air or gas from the pipes and fittings. This is also true of smaller refrigeration and air conditioning systems and identifying and repairing leaks can make the system more efficient and cost effective to run. While large leaks can be fairly obvious this is not the case with smaller leaks and using an ultrasonic leak detector can be an effective way of identifying these for repair.

An ultrasonic leak detector detects the leakage of high pressure air or gas from a system by sound. Gas escaping from a system makes a hissing sound and while in larger leaks this can be heard by the human ear, in smaller leaks the frequency of sound is too high to be heard. However an ultrasonic sound detector can detect this noise and turn it into an audible sound that can typically be heard through a set of headphones. An LED light on a device also provides an indication that a leak has been found. This lets you focus in on the area of a leak and identify its location and once found it can be repaired.

An ultrasonic leak detector is a fairly sensitive instrument and is capable of detecting most leaks from a distance of up to 20 feet away. However as it is focused on a limited bandwidth of sound, noise such as wind, traffic, voices and machine operation will not be detected and it can therefore be used in most situations to detect leaks. The detectors have a number of applications and can be used on compressed air systems in factories, refrigeration systems and air conditioning units. It can also be used for smaller jobs such as vehicle brake systems, radiators and tires.

There are a few manufacturers that produce ultrasonic leak detector equipment and some of these include UE Systems Incorporated, Superior Signal Company, Amprobe and Inficon. These produce a range of detectors which use ultrasonic methods of air leak detection. Depending on the size and sophistication of the device the cost can vary from $200-$300 at the more affordable end of the market to around $3,000 for more expensive models.

Most ultrasonic detection equipment for leaks is hand held and one of the more popular devices on the market is the Whisper Ultrasonic Leak Detector by Inficon. This costs around $280 to purchase and uses sophisticated circuitry to identify the source of leaks. It also includes internal noise control which keeps it unaffected by other noise sources meaning it can easily be used in noisy environments to detect leaks.

At the more expensive end of the market the Accutrak Ultrasonic Digital Leak Detection Kit by the Superior Signal Company costs $3,000 to purchase. This includes advanced digital circuitry which is computer controlled to greatly improve the accuracy of testing. It is a hand held model including two permanent sensors which offer a wide range of detection from sonic to ultrasonic. It comes supplied in a hard carrying case meaning it is easy to transport and should not suffer any damage in transit.

An ultrasonic leak detector is an effective way of identifying leaks in large and small compressed air systems. Repairing these can make a system more efficient and cost effective. Therefore purchasing a detector can be a worthwhile investment that will save you money in the long run.
