Description of the airborne sound sensor BS10
2.1 Applications and designated use
The airborne sound sensor with accessories for different testing work has been specially
designed for the following tasks:
Detection and evaluation of leaks in compressed air, gas and vacuum systems
(depending on the app)
Tightness Testing of windows, doors, vehicles or containers
(in combination with the SONAPHONE T ultrasonic transmitter)
Detection of electrical partial discharges and insulation damage
2.2 Functioning
The sensor attachments
guide the ultrasound to the ultrasonic microphone.
The ultrasonic microphone
inside the sensor converts sound pressure fluctuations in the air to
an electrical signal over a wide frequency range. This electrical signal is amplified and
digitalized within the sensor. Further data processing and output takes place in the testing
device.
The target laser
helps with the precise location of damaged areas:
If the sensor points towards the damaged area during the search, the precise location can be
detected by means of acoustic signals, by pivoting the sensor and searching for a local
maximum sound level. The target laser marks the approximate position of the damaged area.
The LED light
serves as a torch, making it easier to search for damaged areas in poorly lit
environments.
