Device description
3.1
Designated use
The SONAPHONE T is a special ultrasonic transmitter and serves as an
auxiliary device for ultrasonic detectors in the SONAPHONE series for leak
testing. The device provides detection of seal failures in windows, doors,
cabins, climatic cabinets, vehicles or containers, which have sealing
surfaces or rubber profile seals.
3.2
Measuring method and functioning
The SONAPHONE T transmits high-frequency signals in the ultrasonic
range. If you place the ultrasonic transmitter for leak detection in a closed
system, the ultrasonic signals escape via leaks in the system and can be
identified there using an ultrasonic detector in the SONAPHONE series.
Modulation of the signal is used in cases where it is expected that
background noise will interfere with the sounds being analysed. The sound
intensity can be set individually, so that both small and large leaks can be
located.
