The ultrasonic transducer 200k, which works with 200 kilohertz (kHz) frequency, is a mainstay in many industries, from manufacturing to telecommunications. Unlike traditional loudspeakers or microphones, which convert electrical energy into sound or vice versa, these transducers are engineered to work in the ultrasonic range — beyond human hearing — and thus have specialized applications.
Buyers prioritize transducers based on factors such as precision measurements and the ability to penetrate solid materials for non-destructive testing (NDT).
These are the most commonly used ultrasonic transducers; these employ piezoelectric ceramics, often barium titanate or lead zirconate titanate, as the key material. These transducers generate ultrasonic waves when an electric field is applied to piezoelectric crystals. Conversely, these crystals produce an electric charge when subjected to ultrasonic waves, facilitating non-destructive testing.
These can be in the form of bolts or installed in handheld ultrasonic thickness gauges. In these gauges, these transducers emit and receive ultrasonic waves that measure the thickness of various materials. Other places these can be are in ultrasonic cleaners that use ultrasonic waves to remove dirt from items. Ultrasonic flaw detectors also use piezoelectric transducers to locate problems in solid materials.
These use variations in capacitance to generate or detect ultrasonic waves. Human ears cannot detect the waves, but they have focused applications in sensor systems. In sensors, small changes in distance or object position affect capacitance. Applied capacitance measures object distance in automation systems. Fluctuations in distance cause ultrasonic waves, affecting capacitance and consequently object distance. Other applications include detecting liquid levels in maintaining safety in storage tanks.
Cylindrical holes and flat surfaces are where capacitance transducers mount. Easy installation on non-metallic surfaces is an added advantage. Furthermore, capacitive transducers have negligible current draw. Hence, they are energy-efficient, making them ideal for battery-operated devices.
This type of transducer uses magnetostrictive materials to work. Such materials include alloys of nickel and rare earth metals. Magnetostrictive transducers generate ultrasonic waves by twisting in response to a magnetic field. Conversely, they also produce a twisting effect when ultrasonic waves are applied.
Magnetostrictive transducers are mainly applied in high-precision settings, especially in round systems. For example, they are in position sensors that measure the exact place of an object. Other commonplaces are in military-grade equipment, where accurate readings are vital. They are also used in guided-wave ultrasonic testing for long-distance inspection of pipes and industrial structures.
Ultrasonic transducer buyers consider both the performance and application of the transducers. These factors depend on the materials chosen to fabricate the transducers. Some materials commonly used in constructing ultrasonic transducers of 200kHz are discussed below.
This is the most commonly used material for constructing ultrasonic transducers, such as the 200K ultrasonic transducer. The reason for the frequent use is the ease of obtaining these ceramics and their ability to reliably generate and receive ultrasonic waves.
Often, manufacturers use lead zirconate titanate. Occasionally, they use barium titanate for these transducers. These two can be easily modified to work at various frequencies, including the critical 200kHz. In addition, piezoelectric ceramics hold up to temperature and mechanical stress. These factors lead to their suitable usage in industrial environments.
Magnetostrictive transducers commonly use metal alloys like nickel and zircon rare-earth elements. These materials are preferred because they produce a twisting effect when subjected to a magnetic field. This twisting effect generates ultrasonic waves. These transducers excel in high-precision applications like guided-wave ultrasonic testing.
Transducer manufacturers often use electroacoustic polymer composites to achieve specific outcomes. 200kHz ultrasonic transducers manufacturers often use these materials. Such composites usually contain piezoelectric polymers like polyvinylidene fluoride (PVDF). PVDF may not be as effective as lead zirconate titanate, but it's more flexible. This flexibility permits its use in medical imaging devices that require the transducer to be in curved surfaces.
Moreover, these materials are lightweight compared to ceramics and metallic magnetostrictive alloys. The polymers are indispensable in applications where the transducer needs to constantly work. These materials are resistant to fatigue over prolonged use, making them ideal for the function.
The 200kHz ultrasonic transducer's ability to generate high-frequency waves enables precision and non-contact operation, making it invaluable in industrial inspections and quality control. Ultrasonic transducer suppliers frequently sell these transducers to buyers for the following uses.
The transducer's high frequency and fine resolution make it excellent for detecting tiny defects in thick materials. Ultrasonic transducers are crucial in industries like aerospace and power generation to check metal and weld integrity.
Aerospace and power generation check large components with ultrasonic transducers, looking for invisible issues like microcracks and inclusions. These companies value the ability of the 200k transducer to provide detailed images of an item's internal structure. Manufacturers have applied these transducers to ultrasonic testing systems, offering complete inspection solutions by integrating multiple components.
Medical imaging systems use 200kHz ultrasonic transducers for diagnostic imaging and therapeutic applications. The transducer can help ultrasound physiotherapy systems for tissue repair and pain relief.
Medical companies use ultrasonic transducers to obtain highly detailed images during prenatal checks. Medical diagnostic ultrasonic transducer buyers look for models that will generate sharp images for effective medical imaging in hospitals. Those available retail and wholesale usually package the 200kHz transducers and diverse medical tools to sell as viable solutions for clinics.
Auto parts and tool companies are increasingly installing ultrasonic transducers in parking sensors, collision avoidance systems, and adaptive cruise control. The transducer's fine resolution and ability to detect obstacle distance and position accurately make it valuable for improving vehicle safety systems.
Buyers who supply automotive manufacturers with parking and collision sensors seek transducers that will give their customers accurate readings of an obstacle's distance and position. These transducers help improve high-tech sensor systems used in autonomous vehicles.
Buyers consider many factors when selecting ultrasonic transducers for their businesses. Here are the critical factors they consider.
Directional sensitivity, or directivity, is an important factor affecting the transducer's beam pattern. Narrow beam transducers are ideal for long-range or focused applications like flaw detection or depth profiling. This is because they provide depth resolution. However, they are harder to work with because it is difficult to position them correctly.
Conversely, wide beam transducers are easier to handle and position. In addition, they are more forgiving in application. However, they offer less depth resolution and are unsuitable for tasks that require high precision. Buyers consider this factor because it impacts the effectiveness of the transducer in a given use. Therefore, they select a transducer with the right beam profile (narrow or wide) for their target's ultrasonic application.
The frequency is another key factor to consider when choosing an ultrasonic transducer. The frequency affects how deep ultrasonic waves can penetrate a material and the resolution of the data received. Simply put, the higher the frequency, the finer the resolution. Conversely, lower frequencies can penetrate deeper. This is why ultrasonic transducers come in various frequencies.
Each frequency serves a different purpose. For example, the 200kHz ultrasonic transducer the buyer needs is suitable for medical imaging. It is also appropriate for non-destructive testing and precision sensors. On the other hand, transducers for industrial cleaning or heavy-duty applications usually have lower frequencies.
Buyers consider material compatibility when selecting an ultrasonic transducer by looking at the materials used in its construction. Such materials include piezoelectric ceramics, metals, and polymers.
For example, ultrasonic transducers manufacturers prefer constructing transducers with piezoelectric ceramics like lead zirconate titanate and barium titanate. These materials are easily modified to have a wide range of operating frequencies. They also perform well under extreme conditions like high temperatures and pressures.
In addition, ultrasonic transducer manufacturers use metal alloys and polymer composites. The metal alloys are for magnetostrictive transducers, while the composites are for electroacoustic transducers. Buyers consider historical usages of materials when selecting the transducers. They do this so that they select a transducer that yields better performance for what the end user needs.
A1: An ultrasonic transducer is a device that converts electric energy into sound waves. Conversely, it can also convert sound waves back into electric waves. These transducers use capacitive technology to generate and detect ultrasonic waves. They do this by varying capacitance to produce ultrasonic waves and vice versa.
A2: Ultrasonic transducers convert electrical energy into mechanical energy. They do this by generating ultrasonic waves. They have two main components: a piezoelectric element and a coupling medium. When an electric current passes through the piezoelectric element, it vibrates and produces ultrasonic waves. The coupling medium then transmits these waves for the intended purpose.
A3: Buyers use high-frequency transducers like the 200kHz variant in precision applications. The applications include non-destructive testing, medical imaging, and fine-resolution machining. Conversely, low-frequency transducers are for heavy-duty industrial cleaning, drilling, and cutting. They are also for applications where greater depth penetration of the waves is needed.
A4: Buyers should select a transducer with strong materials or temperature-resistant coatings. These include ceramics, metals, and polymers. These materials optimize transducer performance while shielding it from environmental damage. This factor enhances endurance, especially in environments that are very harsh.
