Visual leak detectors include fluorescent dyes and bubble solutions. The former make use of ultraviolet lamps and illuminate when injected into the system. They are great in finding small leaks. On the other hand, bubble solutions are best used to find areas where leaks are most likely to occur since they are highly sensitive.
While the efficiency of both techniques is above reproach, there should be access to the leak by the lamp. Additionally, the leaks must be accessible by the eye. This means that they must be within the user’s line of sight for them to be found out.
These types of detectors are usually used to find out refrigerant gas leaks. They are highly sensitive to very little gas traces and they are popular with manufacturers of packages whose aim is to detect leaks which loose only a few ounces after a long period. However, there will be no alarm if the gas does not pass through the sniffer detectors sensor. In addition, it would be hard to capture the gas in windy situations since it is likely to be blown around.
The detectors help find out ultrasonic leak sounds that cannot be detected by the ear. They are incredibly efficient in picking out the smallest sounds even in the absence of high pressure. Nevertheless, they are limited to sound and may be helpless when it comes to detecting gas leaks. Further, they are designed to pick out a certain sound band and may be, therefore, inefficient, in finding out sounds produced by the usual operations such as traffic, voices and noise coming from the wind.
Leak detection is one of the most important stages in product packaging. However, many manufactures of packages depend too much on the sensitivity of the equipment. Often, they overlook other important factors including the environment and nature of the package. Remember, no leak detection equipment is fully efficient in picking out every type of leak in every situation. Ensure that you understand the limitation of every equipment and technique in order to avoid frustrations and losses brought about by picking the wrong equipment for the job.
