8.4.3. Introduction in ultrasonic transducer mounting

Basic structure of the ultrasonic transducer:
The ultrasonic transducer (F10 and F20) consists of a transducer carrying
element and the actual ultrasonic transducer. The ultrasonic transducer is
made of plastic (PEEK) that has a beige colour and is protected by means
of a metal sheath. The transducer is secured by means of a knurled screw
that is passed through the transducer support. This support can be shifted
in axial direction (blue arrow) with the help of the knurled screw (A).
The ultrasonic transducer type F05 consists only of the sensor sheath and
the actual ultrasonic transducer.
