为运输部门提高车辆气密性检测开发的质量控制应用。把超声波发射器放在容器内部，由于其属性，这些波能可以穿透小孔，在容器外使用SDT超音波气密性检测仪检测，检查者能迅速找出缺陷源，它们可能变成潜在的漏水或风噪点。目前的使用部门：

　　海洋工业—货船的舱口盖

　　汽车—汽车漏风和漏水

　　航空—飞行器和直升机的完整性

　　交通—卡车、巴士、火车

　　建筑—建筑外墙完整性

　　核设施—围墙完整性

　　军事—潜艇、飞行器、航天器

Tightness Integrity - Wind Noise & Water Leaks.
Quality control applications were developed for the transportation sector to improve the tightness of vehicles. The method consists of flooding the interior of a volume with ultrasound waves. Due to their very small wavelenght these can penetrate tiny holes. Using an SDT detector on the outside of the volume, inspectors can quickly pinpoint the source of defects that could become potential sites of water leaks or wind noise. Current sector uses:

Auto - Wind and Water Leaks on Cars
Aeronautics - Integrity of Aircraft and Helicopters
Transportation - Trucks, Buses, Trains
Buildings - Integrity of Building Envelopes
Military - Submarines, Aircraft, Space Vehicles
Nuclear - Containment Wall Integrity
