What are the precautions when using an ultrasonic transducer?

An ultrasonic transducer is a device that is used very often by a great variety of industries. It can generate sound waves in the ultrasonic range above 18 kHz by turning electrical energy into sound energy. And it can be combined with a bunch of machines to complete different kinds of work. What a magical function the ultrasonic transducer has!So, what precautions are needed to keep in mind before operating it? Please allow me to introduce this to you in detail.

What is an ultrasonic transducer?

ultrasonic transducers are devices that generate or sense ultrasonic energy. The components of an ultrasonic transducer can be divided into three categories: transmitters, receivers and transceivers. The transmitter converts electrical signals into ultrasound, the receiver converts ultrasound into electrical signals, and the transceiver can send and receive ultrasound. To put in a more specific way, the active components of piezoelectric materials can convert electrical energy, such as excitation pulses from a flaw detector into ultrasonic energy. The most commonly used materials are polarized ceramics that can be cut in many ways to produce different wave modes. New materials such as piezoelectric polymers and composites are also being used in applications that are beneficial to the performance of transducers and systems.

What are the precautions when using an ultrasonic transducer?

When using an ultrasonic transducer, there are various precautions to keep in mind, of which the main consideration is the matching with the input and output ends, and then the size of the mechanical installation and matching. The frequency of the transducer is relatively intuitive. Frequency refers to the frequency measured by the transmission line method using a frequency (function) generator, millivoltmeter, oscilloscope, etc., or the frequency measured by a similar instrument (such as a network impedance analyzer). Usually called the small-signal frequency. The customer connects the ultrasonic transducer to the driver power supply through a cable and measures the actual operating frequency when there is no load or there is a load after power-on. Because the customer's matching circuit is different, the frequency of the same ultrasonic transducer in different driving power sources is also different. Also, you need to check that the contact surface should be smooth and free of scars. If there is a scar, please lightly sand it with sandpaper, since it is required to be able to grind down defects without destroying the flatness of the contact surface. Last but not least, never forget to check whether the ultrasonic transducer has been correctly and safely plugged in, whether the socket has its stable power supply, I don’t think you would ever happy to see the whole production line stops to fix the power issue.

If you are looking for a reliable ultrasonic spot transducer to purchase, please make sure you check out the ones in Hangzhou Shengpai Technology Co., Ltd, their nice and high-quality machines are definitely appealing to your unique taste.
