UE ULTRASONIC LEAK DETECTION SYSTEMS: ADVANCED ULTRASONIC MONITORING

Imagine, an instrument so sensitive and so fast that it can sense the human eye blink, and display it on a meter when it happens! Welcome to the marvelous world of UE Systems Ultrasonic Monitoring. Systems so sensitive, so versatile, they can detect a wide range of leakage from gross to fine in a variety of configurations.

24 HOUR SUPPORT FOR YOUR AUTOMATION SPECIALIST

UE Systems Engineering Staff is here to make sure you get the correct system for the job. We have the expertise to recommend whether or not to use Liquid Leak Amplifier, what type of Sound Isolation Enclosure you may need or advise on specialized testing formats for difficult configurations. As you study the Liquid Leak Amplifier Application Examples and the Sound Enclosure Descriptions, bear in mind that you can contact us any time for advice via e-mail, fax or telephone.

UE LEAK DETECTION SYSTEMS OFFER VARIETY, FLEXIBILITY

UE Leak Detection Systems provide design flexibility. A part may be tested or a component monitored through one of three modes.

prsr

PRESSURE

During a pressure leak, as the fluid escapes it produces a turbulent flow with strong ultrasonic components. Since ultrasound is localized to the point of emission, the leak can be readily detected. Leak rates to as low as 1x10Ø3 ml/sec. may be detected.

vcm

VACUUM

A gas passes from the atmosphere side to the vacuum producing a turbulent flow that generates ultrasound. Since the ultrasound is produced in the vacuum side, the detectable leak rate is slightly lower than that of a pressure leak.

LIQUID LEAK AMPLIFICATION

For low level leaks that fall below the threshold limits of either the pressure or vacuum method, this patented test uses a liquid with a low surface tension that is applied to the test area. When a small bubble forms and immediately collapses. The "bursting" produces a strong ultrasonic signal. Leak rates as low as 1x10Ø6 ml/sec. are capable of being detected. The advantage of this method is that, aside from low level leaks, gross leaks that, under pressure might push the liquid aside, will be detected.




Typical Liquid Leak Amplifier Application Examples

DM: Dunk Method:
The parts are immersed in LLA and the excess liquid is recycled through a filter to remove contaminants.

WM: Waterfall Method:
The parts are run under a waterfall of LLA and the excess liquid is recycled through a filter to remove contaminants.

SM: Spray (or Mist) Method:
A liquid stream is directed to a particular area on the part so that the remaining areas stay dry.

An optional approach to the above applicator configurations is to use available personnel to manually apply LLA with a sponge or wet fabric directly to the test area before it passes by a scanner.

Sound Isolation Enclosures

There will be instances where surrounding ultrasounds will interfere with test results. Since ultrasound is a high frequency, short wave signal, simple test chambers or shielding techniques can be used. Enclosure barriers can be constructed with sheet metal, aluminum, fiberglass, steel plate or even wood. Consult with the factory for advice.

MONITOR / TEST LEAKAGE TWO WAYS

  • REAL-TIME SCANNING
  • LIQUID LEAK AMPLIFICATION

THE ULTRASONIC PRINCIPLE

UE Dedicated Systems sense ultrasound frequencies between 20 kHz and 100 kHz. Since ultrasound is a high frequency, short wave signal, it has certain properties that make it an ideal medium for on-line leak detection and product quality inspection. These minute sound waves tend to be highly directional and localized. The source of emission can be located and isolated from other non-essential sounds providing accurate test results. Sensing at the speed of sound, the onset of a monitored ultrasonic event will be detected in real-time.

UE LEAK DETECTION SYSTEMS: AUTOMATIC TEST VALIDATION

Only UE's Leak Detection Systems have Modular Sensitivity Validation. This unique feature assures accurate leak testing. Each microphone in the system has a white noise transmitter. The transmitter emits a white noise simulating a low level leak.

With UE's Modular Sensitivity Validation, the microphone can be challenged prior to every test. No need to wait to test per shift, hour or day. There are no orifices that can clog up . . . no stocking costs for spare test orifices.

UE MODULAR SENSITIVITY VALIDATION TRANSMITTER AND SCANNING MODULE

Each scanning module is a patented phased array of transducers designed for increased sensitivity and directionality when sensing airborne leak signals.

PLUG & PLAY - How Many Channels Do You Want?

With UE's "Plug & Play" feature you can order from 1 to 12 channels. Each channel in a UE Leak Detection System has its own signal processing module that can be easily removed or plugged into place while the unit is in operation. Since each channel is independent, it has no effect on the system as a whole. In the unlikely event that a channel is damaged, the rest of the system can carry on while the effected component is easily replaced.

Designed With You In Mind

UE Systems standard units include so many features that in most cases all that is required is to plug them in and start testing. Should your testing require special considerations, we offer engineering assistance to meet your needs.
