T700 ultrasound inspection set – application possibilities
Leak detection in compressed air systems
Even a tiny hole no bigger than 1 mm ( 0.039 ins) across can cause a pressure loss of as much as 0.1 m³ (0.13 yd³) per minute in a system which carries a pressure of 10 bars (145 psi). Such hardly noticeable leaks can quickly run up additional costs which can add up to as much as 700 euros (over 600 pounds) a year – per leak that is!
And there is normally more than just one leak. Our experience has shown that as much as 30% of the compressed air that goes through the pipes or systems never gets to where it is needed because of multiple leaks in the pipes or hoses, leaky valves or couplers or other connecting pieces.
What most people don’t know is that the air which leaks out of these tiny holes produces ultrasound waves whose frequency are too high to be picked up by the human ear. These ultrasound waves, which are produced by the friction of the compressed air passing through the tiny holes in the pipes or hoses, can, however, be picked up by the T700 and converted into sound waves which can be heard over a pair of connected headphones or transformed into a value which can be read off the device’s display.
And because the T700 is able to blank out noises which might otherwise make it difficult to hear the sounds coming in over your headphones, it can even be used it to locate leaks while production or other activities are in progress.
Inspection of components to check them for leak tightness
The T700 can also be used in combination with the T710 ultrasound transmitter to perform quick, easy and low-cost leak checks in systems without compressed air.
The T710 emits ultrasound waves which travel through the system and leak out through any tiny holes or faulty connections in the system. These waves are then picked up by the T700 which can then reliably determine the exact position of the holes or fissures which are the cause of the leaks.
This failsafe method provides you with a reliable means of determining whether profiled sealing strips or magnetic seals on tanks, containers and other system components are leaktight.
In order to check an object for leak tightness, simply place the ultrasound transmitter inside the object that needs to be checked and then travel round the outside of the object with the T700 in order to see if any ultrasound waves leak out to the outside.
This same principle can be used to determine whether climate chambers, ventilation systems, window frames, door seals or fireproof doors are leaktight or not.
This then is why the T700 ultrasound inspection set provides the ideal solution for carrying out quality checks during individual construction phases or for inspecting energetic deficiencies.
