CTU in operation
Perform ultrasound test (optional)
CAUTION
Ultrasonic cavitation noises
Danger of hearing injury
►
If you come within 5 m of the CTU, wear
hearing protection.
The principle of the ultrasonic effect is that the ultrasonic vibration systems
transform the electrical energy from the high-frequency generator into
mechanical energy.
The vibrations conveyed into the analysis fluid cause microscopic hollow
spaces to be constantly formed which implode upon themselves. This effect
– referred to as "cavitation" – causes contamination to be removed, in so
doing accelerating the physical process.

For the ultrasonic test, replace the grating in the clean room with the proper
device, such as a freely hanging basket.
Hang the basket retaining frame [a] with the basket [b] in the corresponding
thrust bolts in the clean room.
