Ultrasonic Inspection: Non-Pressurized Systems

Ultrasonic Testing

In the scan mode with the UL101 Universal Transmitter (UT2000), the user can detect and pinpoint leaks in non-pressurized vessels, cavities, pipes, housings, hoses, rooms, heat exchangers, vehicle and equipment cabs, ship hulls and galleys, airplane cabins, train cars, etc.

By placing the Universal Transmitter 2000 (UT2000) in any kind of enclosed space, an equipment or truck cab, you can create a sense of pressure by overfilling the space with ultrasound. Then, you can simply scan the seals and gaskets with the UL101 receiver to detect and pinpoint escaping ultrasound that indicates a leak.

If the orifice to the container/vessel/cavity is smaller that the transmitter, then you can insert ultrasound by attaching one of the acoustic probes to the transmitter. Sometimes a 3/8-inch OD diameter flexible hose is attached to the one-inch acoustic probe. This vessel/cavity testing procedure is much quicker and easier than soap bubble and hydrostatic testing. It will sometimes locate leaks that these procedures cannot locate. If industry standards require soap bubble and/or hydrostatic testing, the user can pretest using the UL101 in scan mode with Universal Transmitter. By pre-testing, the user can eliminate multiple soap bubble or hydrostatic tests. The UL101 in scan mode with Universal Transmitter can also augment these procedures to make them even more reliable.
