Helium leak detection is a way to perform “nondestructive” testing. There are other leak detection methods but none considered as accurate in terms of localizing and quantifying, as helium leak detection method.
A Leak Detector such as the one T-SEC owns is useful for turbine, condenser, and exchange systems.
INFICON T-Guard™ Leak Detection Sensor delivers the sensitivity and speed helium leak detectors are known for, at a cost similar to pressure decay systems.
It works with simple chambers at atmospheric pressure, so there is no need for costly and complex high vacuum chambers and pumps. That makes automated systems based on T-Guard an attractive alternative to pressure decay and water bath leak detection, providing up to 100 times the sensitivity with low cost of ownership and high ease of use. The measurements are also highly repeatable, even with large, warm or humid test objects.
Wherever pressure decay and water bath systems are used or are not sensitive enough
Leak detection for water coolers and radiators
Big valves, e.g. for chemical applications
Manufacturers of automotive gas lines and tanks, small heater coils, etc. that are now demanding greater leak tightness
Leak detection involving warm, humid or large parts, where the pressure decay method is ineffective
Other markets where helium vacuum leak detection has been considered too costly or too complex
