IP68 Waterproof Ultrasonic Transducer Sensor with 0.10～1.5m Range and Plastic Housing
1.Introduction
Ultrasonic transducer is a device that converts electrical energy into ultrasonic energy (mechanical vibration energy), or vice versa. It is an important component of ultrasonic equipment and is widely used in medical diagnosis, industrial inspection, cleaning, welding and distance measurement.
Ultrasonic transducers are indispensable devices in modern science and technology and are widely used in various fields. Their high precision, high sensitivity and non-contact measurement characteristics make them important in industrial detection and medical diagnosis. With the development of technology, the performance and application range of ultrasonic transducers will continue to expand and improve.
The working principle of ultrasonic transducers is based on the piezoelectric effect or magnetostrictive effect:
- Piezoelectric effect: Piezoelectric materials (such as piezoelectric ceramics, quartz, etc.) will undergo mechanical deformation when voltage is applied, and conversely, they will generate electric charge when subjected to mechanical pressure. By applying an alternating voltage, piezoelectric materials will produce mechanical vibrations, thereby emitting ultrasonic waves.
- Magnetostrictive effect: Some magnetostrictive materials will change size under the action of a magnetic field. Through an alternating magnetic field, these materials can be vibrated and then emit ultrasonic waves.
