FLEX.US Ultrasound Leak Detector

The SDT FLEX.US detector works like a super microphone, sensitive only to high frequency ultrasounds. Using a sensitive piezoelectric crystal as a sensor element, minute high frequency sound waves excite or “flex” the crystal creating an electrical pulse that is amplified and then “heterodyned” or translated into an audible frequency that the technician can hear through a pair of noise reduction headphones.
