If you want to find a hole in vessel or a tank, there is a good chance that ultrasonic can help.
Often called ‘UT’ or ‘UT testing’ this involves the generation of ultrasonic sound using an ultrasonic transmitter, placing this physically on one side of the object/item you are testing and then checking with a receiver tuned to the transmitter frequency to see if there is any ultrasound. The ultrasound can only go through an air hole meaning it detects any air leaks.
Ultrasound is not audible so the receiver converts the ultrasound to an audible sound.
This audible sound is heard through headphones or a small internal loudspeaker. If you want to know the size of the hole, then we have products that will display the intensity in decibels. Decibels are the universal unit for sound measurement.
If it needs precision measurements, we suggest our Door-Safe.
