Fuji Ceramics Langevin Type Ultrasonic Transducer For Processing Machines
Manufacturer: Fuji Ceramics Co., Ltd.
Model: Langevin Type
Features
- This ultrasonic vibrator uses a monolithic structure with piezoelectric elements clamped between two metal blocks, named after inventor P. Langevin.
- Most models use ring-shaped elements tightened with bolts, known as bolt-clamped Langevin-type vibrators.
- It provides high power and large vibration amplitudes for effective ultrasonic energy use.
