Ultrasonic sensors
Revised fifth generation ultrasonic sensors on the
new Audi A5. These sensors have new isolating
rings made of a material which exhibits enhanced
thermal properties.
There is an internal and an external isolating ring.
These two rings allow the membrane to oscillate
upon excitation and thus produce ultrasonic waves.
