Applications: Ultrasonic cleaning, Ultrasonic clean machine, Ultrasonic Sensor, Vibration Sensor, Wall thickness sensor, the Material stress sensor, Pressure sensor, Vibration generation, Energy/Electricity harvesting, Biodiesel mixing transducer, Fishfinder transducer, and others.


Notes: The max voltage that this transducer can withstand is 1050V, but the most important issue is the maximum power allowed which is 55W. If the input voltage is increased up to the maximum value, the power should always be kept below the max power. Of course, the maximum power will be dependent on the bonding job. So the operation voltage we suggest is 280V. The wrap around electrode has the negative polarity.
