HOW ULTRASONIC SURVEYS WORK
The ultrasonic survey handgun senses high frequency sounds produced by operating equipment, leaks and electrical discharges. The ultrasonic survey handgun electronically translates these signals by heterodyning them down into the audible range so that a user can hear these sounds through a headset and see them as intensity increments on the meter.
Heterodyning works the same as a radio in that it accurately transforms the sounds so that they are easily recognised and understood.
Ultrasonic leak detection survey is extremely broad based. Sensing ultrasounds generated by a leak, the ultrasonic survey handgun can be used to locate leaks in pressurised systems regardless of the type of gas used. This is especially beneficial in areas where there is a saturation of gases or where a wide variety of gases, pressurised vessels and vacuum processes exist.
Ultrasonic survey guns can also be used to detect flow turbulence problems that occur in fluid power, water or steam systems. Identification of a problem will then involve the replacing of defective parts or redesigning a system
Ultrasonic surveys can assist thermography on high voltage systems as they are able to detect discharges that occur due to air being ionised either through defective connections, defective contacts or loading.
Time and convenience are also improved with ultrasonic detection since equipment may be tested while on-line.
The advantages of ultrasonic survey technologies are simple to understand. Ultrasound is a high frequency, short wave signal. When compared with the sounds that humans can hear, the size of the sound waves are extremely small.
This property provides advantages:
- Ultrasound is very directional
- Ultrasound can be easily blocked or shielded
- Ultrasound instruments can be used in noisy environments
- Ultrasound changes provide early warning of potential problems
ERIKS offer the service of an engineer to tour a site with a client´s representative and identify with a label and / or digital photograph. A hand written report is submitted before leaving site and a fully bound report will follow shortly.
