20khz ultrasonic transducer replacement for Herrmann KHS20-IP50
The 35 kHz Replacement Ultrasonic Herrmann Converters 35/1000-S-IP65 Typeis applied to Herrmann type ultrasonic welding machine.
The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.
