About low frequency ultrasonic transducers

Types of Low-Frequency Ultrasonic Transducers

Low-frequency ultrasonic transducers come in different types. Each one is suitable for particular uses. These devices change energy systems. In this case, the electric power becomes mechanical energy. Often, it is through ultrasonic waves in liquids. The range for low-frequency transducers is between 20 and 400 kHz. Common types include:

Piezoceramic Transducers

This transducer is the most common. In many cases, people use it for industrial cleaning. The transducer generates high ultrasonic waves. This makes them suitable for low-frequency ultrasonic baths. The cleaning process uses cavitation bubbles. They produced the bubbles during the ultrasonic cleaning process. The piezoceramic transducer is made of ceramic material. The material is coated with a piezoelectric layer. The layer creates ultrasonic waves when it is energized.

Magnetostrictive Transducers

The magnetostrictive transducer is another type. People often use it in non-contact cleaning methods. The device converts pulsed electric currents. It uses a magnetic core to produce ultrasonic waves.

The active materials are usually rare earth metals, like Samarium or Neodymium. These are embedded in steel. They are also parti9ally replaced with a magnetostrictive alloy. The waves tend to be more focused with this type. This allows for the cleaning of small areas with precision.

UJT Transducer

The Unijunction Transistor (UJT) is used in low-power applications. These transducers are ideal for small ultrasonic cleaning baths. The device generates ultrasonic waves by converting electric currents. It is suitable for users doing light-duty cleaning tasks.

LDT Ultrasonic Transducer

It is short for linear displacement transducer. This transducer works on the principle of converting mechanical displacement into electrical signals. People often use it in precision measurement applications. These include industrial inspections or measuring the thickness of materials.

RS232 Transducers

RS232 transducers are used for data transmission. This is in ultrasonic distance measuring equipment. They convert distance information into an electrical signal. The signal can then be transmitted to a computer or data logger for analysis.

Industries That Use Low-Fidelity Ultrasonic Transducers

Low-frequency ultrasonic transducers are valuable devices. They work in many areas of life and in many industries. These transducers are efficient tools that industrial users find reliable.

Industrial Ultrasonic Cleaning

Ultrasonic cleaners are used to clean complex metal components. This is because the ultrasonic waves can penetrate even the tiniest cracks. It ensures that the piece is thoroughly cleaned. The transducers efficiently remove grease, dust, and other particles. This makes the process faster than manual cleaning.

Medical Diagnostics

In the medical field, these transducers are used in non-invasive diagnostic equipment. They create images of internal body structures. For example, the prenatal baby checkups doctors do via ultrasound. The equipment uses transducers to produce images. These images allow practitioners to check the fetal development of their patients.

Material Testing

Low-frequency transducers are commonly used in Non-Destructive Testing (NDT) of materials. They help detect internal flaws and measure material thickness. The ultrasonic waves can travel through a material and reflect back. This allows technicians to identify any cracks, voids, or other defects that might be present. These transducers ensure the safety and reliability of critical structures like pipelines or bridges.

Sonar Systems

In the defense and marine industries, these transducers are used in SONAR systems. The systems help locate underwater objects and map seafloors. The transducers send out ultrasonic waves. They then measure the time it takes for the waves to bounce back.

Agriculture

These transducers measure soil moisture levels in agriculture. This information helps farmers optimize their irrigation systems. It, therefore, leads to better crop yields without wasting water. They are also used in livestock monitoring systems. They help track the health and activity levels of farm animals.

Food Processing

In food processing, they are used for high-Intensity Focused Ultrasound (HIFU). It is a fat-reduction treatment. The transducers create ultrasonic waves that can kill bacteria and microbes. They also help preserve food by preventing spoilage without the need for harmful chemicals or additives.

What To Consider When Purchasing Low-Frequency Ultrasonic Transducers

A buyer should consider the following when purchasing low-frequency ultrasonic transducers.

Frequency

The frequency of the transducer determines how far the ultrasonic waves can penetrate. It also affects how effectively the waves can clean or process a material. Different applications require different frequencies for optimal results. Low frequencies are suitable for deep penetration cleaning. It is ideal for larger items or thicker materials. Conversely, higher frequencies are better for precision work. They focus more energy on a smaller area.

Power Output

Higher power transducers generate stronger ultrasonic waves. The waves are suitable for heavy-duty cleaning or industrial processes. Lower power transducers, on the other hand, are more energy-efficient. They are ideal for lighter tasks. These tasks include medical imaging or small-scale laboratory work.

Material Quality

The material of the transducer will affect its durability and performance. Common materials include piezoceramic and quartz. These are often used for ultrasonic cleaning. They work well for industrial applications. This is due to their robustness and ability to generate strong ultrasonic waves. For medical devices, hypoallergenic and biocompatible materials are preferred.

Application

Buyers should consider the industries where the transducers are used. For example, transducers used for cleaning will have different requirements than those used in medical devices or material testing. Identifying the specific use cases will help in selecting the right transducer for the job.

Environmental Conditions

Buyers should think about the working environment of the transducer. Will they be exposed to harsh chemicals, extreme temperatures, or high humidity? These factors can affect the lifespan of the transducer. Being mindful will help ensure the components are strong enough to handle their surroundings.

How To Use Low-Frequency Ultrasonic Transducers

Knowing what to consider helps buyers select the right ultrasonic transducer. This quality product will serve users for a long time. It is also important for users to understand how to use the transducers to enhance performance.
