Leak Testers Industry Information

Leak Testers

Leak testers offer a wide range of methods and mechanisms designed to detect and measure predominantly liquid and gas leaks in industrial, commercial, and domestic settings. Food production, medical, automotive, and industrial systems frequently use leak testers. Some manufacturers test products and their components before they are released to consumers to ensure quality control.

What Are Leak Testers

Unlike leak detectors, leak testers generally do not monitor systems; instead they are used as a diagnostic tool when a given system is running at less than optimal levels. Appliances using refrigerants and methane gasses should be tested at the first sign of decreased productivity because releasing these materials can be hazardous to health. Leaking gasses can also lead to loss of money and eventually to appliance failure. Depending on the type of leak, the substance can also hurt the environment. As many methods and techniques for leak testing are available, the specifications of the mechanism to be tested should be considered. Pressure decay, mass flow, helium accumulation, vacuum decay, and colorimetric development are some of the many testers available. Some of these systems recognize changes in pressure or flow, while others use chemicals to produce visible reactions at the site of a leak.

Types of Leak Testers

The most simple leak tester, the bubble test, involves submerging a pressurized test subject in water or coating it in a soapy substance, at which time bubbles emerge from the site of the leak. Although the bubble test is effective and inexpensive, it does not apply to sensitive equipment. Leak testers should be carefully chosen for more sensitive equipment and situations. Also, testers do not identify the leaked substance and so are often used in conjunction with liquid or gas analyzers. These products in the leak detection line are meant for fairly specific scenarios, although leak detectors are more generalized. That is why using leak detectors and leak testers together produces a well-rounded solution. A variety of methods exist to detect a leak. Gas detectors use a tracer gas to measure the leak based on its ion charge response to the helium or hydrogen they put into the air. Ultrasonic detectors measure the sound waves emitted by gas leaks to locate and identify a leak. Often these detectors are hand held, since leaks usually originate in complex pipe systems that are difficult to maneuver.

The Resolution That Takes Time

How resolution can effect leak test cycle time. Some time ago we looked at Gage R&R. In that post we suggested that most repeatability studies require a 10% or better repeatability. This is perhaps better expressed as an example. If the leak rate specification for a part calls for a leak rate of 10 sccm then the system must be repeatable to 10 sccm + 1sccm. Because the 10% repeatability encompasses the complete system – part, seals, air lines, valves etc the instrument itself should... Read More About This
