Ultrasonic Cleaner: Types, Components & Applications
An ultrasonic cleaner consists of two core components: an ultrasonic cleaning bath and an ultrasonic generator. The design varies based on application, with differences in bath size, power (W), and frequency (kHz), all determined by the cleaning bath's structure.
1. Ultrasonic Cleaning Bath: Core Construction
The cleaning bath is made of a stainless steel tank and piezoelectric transducers. Transducers are categorized into two types, each suited for specific cleaning needs:

1. Ultrasonic Cleaning Bath: Core Construction
The cleaning bath is made of a stainless steel tank and piezoelectric transducers. Transducers are categorized into two types, each suited for specific cleaning needs:
Type 1: Bolt-Clamped Langevin Transducer
Structure: Sandwiched between metal blocks and secured with a bolt, this design protects piezoceramics from tension stress while maintaining high compression resistance
Key Features:
Frequency Range: 28–40 kHz (low-frequency, strong vibrations)
High Power Output: 60W–1200W, scalable with transducer quantity
Applications: Ideal for industrial cleaners and large-capacity tanks (1L+), such as automotive parts or machinery degreasing
Advantages:
Deep cleaning for stubborn contaminants (grease, rust)
Handles complex geometries via cavitation bubbles
Type 2: Direct-Attached Round Piezoceramic Transducer
Structure: Piezoceramic discs bonded directly to the tank, turning the entire bath into a transducer
Key Features:
Frequency Range: 40–100 kHz (high-frequency, gentle cleaning).
Lower Power: 5W–50W, safe for delicate items.
Applications: Household cleaners (jewelry, glasses, retainers).
Advantages:
Non-abrasive cleaning for sensitive surfaces
Compact design for small items
