Ultrasound Inspection

Inspection with an ultrasound detector (Ultrasound Inspection)

Before getting to know the instrument, you must first know what ultrasound
is ? Ultrasound waves are sound waves with frequencies above the range that can be heard by humans. which is a high frequency sound wave but low power short wavelength They tend to move in a straight line and are easily absorbed by energy. And there are 3 causes of ultrasound waves in factories: Friction, Impact and Turbulence. (Turbulence).

Inspection with an ultrasound detector (Ultrasound Inspection)

compressed air production It’s a costly process. And the loss of compressed air as a result of leaks worsens system performance. and cause unnecessary expenses

SONAPHONE ultrasound detectors and SONOASCREEN cameras can quickly and easily detect leaks. Compatible with compressed air, inert gas and vacuum systems

Tool Applications To find the leak point

from the phenomenon of Turbulence Caused by leaks, our tools can detect leaks. When compressed air flows through the leak, it creates turbulence. accompanied by a high-frequency hissing sound This hissing sound can even be heard in a quiet place. But it is almost impossible to hear inside noisy factories where SONOTEC has technology that filters out unnecessary noise, making ultrasound a simpler and more efficient method of detection. Can generate reliable reports as well.
