Ultrasonic Imaging for Leakage Detection & Partial Discharge
What is Ultrasonic Imaging (UI)
- Ultrasonic Imaging (UI) is the combination of ultrasonic detection with digital imaging, to present ultrasonic energy in a visual aspect.
- It utilises an array of ultrasonic detectors located strategically, thus creating overlapping ultrasonic waves, which allows for pin-point locating of the sound source.
Advantages of Ultrasonic Imaging
- Ultrasonic sources are embedded onto digital image, to allow ease of follow up by assigned technician(s).
- Detection possible at distances up to 100m*.
- Wide detection range of up to 100Hz ultrasound.
- Eliminates the safety issues of personnel entering hazardous zone, working at height, etc.
- Assessment can be executed efficiently without down time and extra cost to access challenging areas. E.g. confined space entry permit, high installations requiring scaffolding.
Why Do We Need It?
- Condition monitoring of hazardous gas systems to identify leakages which pressure leak detectors cannot detect, or in well-ventilated areas where it gets diffused easily.
- Condition monitoring of rare gas supply lines to minimise loss of costly material, inadvertent stoppage of manufacturing process, or product quality compromised.
- Leakage detection to address wastage, which aids energy cost and carbon tax reduction.
- Demonstrates Sustainability effort for ISO14001 & ISO50001.
- Condition monitoring of electrical systems to ensure grid reliability.
