25k transducer ultrasonic

Types of 25k transducer ultrasonic

Ultrasonic transducers are divided into several types based on their operating frequency and functionality.

Piezoelectric transducer

This type of transducer is operated based on the piezoelectric effect. In case the materials experience deformation from mechanical stress, they generate electrical energy. Piezoelectric elements are perfect for ultrasonic cleaning because they can generate several ultrasonic waves over an acoustic spectrum.

Capacitive transducer

A capacitive ultrasonic transducer uses dielectric change to sense the ultrasonic waves. These waves result in electrical signals that are mainly proportional to the waves detected. While these transducers can measure particular frequencies, they might not be as efficient in generating high frequencies as their counterparts.

Magnetostrictive transducer

These are electric components that convert magnetic energy into mechanical energy. They work by sending a magnetic field through a magnetostrictive material, which generates elastic waves or vibrations. Those waves propagate through the material in the form of an ultrasonic sound. These transducers stand out for their robustness and power and cleaning effect on large items.

Microfabricated ultrasonic transducers

These transducers are developed using MEMS (micro-electro-mechanical systems) technology, which allows for great miniaturization and great integration capabilities. MEMS transducers can fabricate great-density ultrasonic arrays, producing highly directed and controlled ultrasound beams. Their small structure makes these transducers useful in applications requiring high spatial resolution, like imaging and targeted drug delivery.

Industrial applications of 25k transducer ultrasonic

25k ultrasonic transducers find diverse applications in many industrial fields.

Ultrasonic cleaning

The 25k ultrasonic transducer is one key component of ultrasonic cleaners. This is where the transducer converts electrical energy into high-frequency ultrasonic waves. These waves create tiny cavitation bubbles in a cleaning solution. When the waves collapse, they release high energy, clean and remove contaminants from complex machine parts, medical instruments, and electronic boards in tight spaces.

Non-destructive testing (NDT)

Such transducers are also used for NDT by sending ultrasonic waves through substances to evaluate their thickness, identify cracks, and detect voids, These waves reflect the internal structure and mark any possible anomalies. This methodology is widely used in structures such as aerospace, factories, power plants, and constructions.

Acoustic imaging

In acoustic imaging, 25 kHz transducer ultrasonic devices are used for contact ultrasonic mapping and visualizing acoustic impedance. In geophysics, for instance, geologists identify subsurface features and mineral deposits that deal with impedance measurements. While producing fine-quality images, the waves will help locate resources such as oil, gas, and minerals, which offer precise information for extraction and make further exploration decisions.

Ultrasonic welding

These ultrasonic plastic welders use transducers to convert electrical energy into ultrasonic energy. The energy is focused on the joint area, causing the materials to loosen. Hence, ultrasonic welding makes strong, durable bonds on such materials and with non-metallic materials like plastics.

Industrial thickness gauging

Many industries commonly use gauging systems for thickness measurement. Typical industries include non-ferrous metal coating, insulation, and paint. The transducer will send ultrasonic pulses through the substrate to obtain the time interval required for the pulses to return. When combined with the ultrasonic velocity of the sound in the substrate, the result is the thickness.

Product specifications and features of 25k transducer ultrasonic

Technical specifications and key features

• Frequency:

  The frequency of a standard ultrasonic transducer is 25 kHz. This is the operational frequency for ultrasonic cleaning used across multiple industries.

• Power:

  It varies depending on the household requirements, from a few watts to several hundred. For cleaning, the cleaning device usually has between 30 to 200 watts of ultrasonic peak power.

• Material:

  25 kHz transducer materials tend to include piezoelectric ceramics, mainly lead zirconate titanate (PZT). Because of their effectiveness in transforming mechanical energy into electrical energy, they are perfect for generating ultrasonic waves.

• Ultrasonic waves:

  The waves produced by the ultrasonic transducers are above 20 kHz, which is beyond human hearing capability. This creates an ultrasonic cleaning effect upon contact with liquids.

• Creams:

  The transducers are developed to sustain or operate within a broad temperature range, mostly between 0 and 60 °C (32 and 140 °F). Higher-power ultrasonic cleaning usually requires a higher working temperature.

• Dimensions:

  The dimensions may also widely differ depending on the construction type. For instance, there are large piezoelectric transducer elements for industrials, while MEMS transducers are miniaturized.

How to install

• Mounting:

  The transducers are securely mounted to a component that generates ultrasonic vibrations. That component may be a generator or converter. Place the transducer on the placed surface and use bolts, screws, or adhesive to secure it firmly.

• Electrical connection:

  Connect the transducer to a power source through the generator. The connector type will widely differ according to the generator used, so consult the operation manual for guidance.

• Calibration:

  The system must have proper calibration before use. The output voltage and frequency need adjustment to meet the transducer's specifications. Perform calibration by using a multimeter and frequency counter to evaluate the output parameters and adjust them as necessary.

• Testing:

  After calibration, conduct a trial run to confirm that the transducers properly generate ultrasonic waves. Use an oscilloscope to determine pulse emissions or set a frequency meter near the transducer to catch sound.

How to use

• Cleaning solutions:

  Use ultrasonic cleaning to begin by filling a basin or tank with water or a suitable cleaning liquid. The cleaning liquid can be a solvent, a chemical, or a detergent that effectively cleans the target items.

• Power on:

  After preparing the solution and items, power on the ultrasonic cleaner. During this time, adjust the temperature and timer settings manually.

• Submerse items:

  Place the items that require cleaning inside the basin or tank. Make sure they don't touch the transducer at the basin's bottom and are fully submersed in the solution.

• Start cleaning:

  Run the cleaning cycle. The transducers start producing ultrasonic waves, creating tiny bubbles that generate a cavitation action upon witness within the solution and clean the items effectively.

Maintenance and repair of 25k transducer ultrasonic

• Regular cleaning:

  Clean the transducer surface after each use to prevent debris or residue from building up and affecting performance. Use a soft cloth or brush to remove particles from the transducer surface. Avoid sharp or abrasive materials that may damage it.

• Inspect fort wear:

  Regularly inspect the transducer for signs of wear, cracked, or damaged cables. Dealing with worn or damaged transducers will affect performance and may cause system failure. Often replace worn out or damaged transducers to ensure proper functioning.

• Check connections:

  Check all electrical connections occasionally for looseness or corrosion. Poor connections can cause inconsistent ultrasonic output or power loss. Ensure the connections are tight and free of oxidation or rust.

• Test system performance:

  Frequently monitor the system's performance. Any output variation in frequency or power might signal a problem within the transducer or other components. Perform responsive tests to catch problems as they occur.

• Vibration isolation:

  Ultrasonic transducers are sensitive electronics susceptible to vibration interference. For this reason, ensure that transducers are well mounted onto vibration-damping materials like rubber or foam.

Quality and safety considerations for 25k transducer ultrasonic

• Sourcing high-quality components:

  Ultrasonic cleaning transducers are numerous and need to be bought from reputable manufacturers who use quality materials. Buying poor-quality components will affect cleaning efficiency, pose safety issues, or lead to swift equipment failure. Ensure proper performing components by conducting research on manufacturers, reading reviews, and checking certifications.

• Equipment testing:

  Testing the equipment before use is mandatory. Users must conduct a test to evaluate ultrasonic output and confirm proper functioning. Attempt running the system without items for a short period. This is to evaluate whether ultrasonic waves are generated. Presence of waves means it's safe to proceed with cleaning.

• Monitoring operating conditions:

  Monitor the equipment operating condition continuously. Any irregularities like strange noises or sparks need to be addressed immediately. Continuous monitoring prevents long-term damage to the equipment and ensures the workspace remains safe.

• Shielding:

  Transducers create ultrasonic sound waves. Some are at harmful levels to human ears. Transducer isolation is important. This means installing them on vibration isolation equipment and building enclosures to shield the user from said ultrasound.

• Personal protective equipment (PPE):

  Manufacturers or users are recommended to wear proper PPE when handling this equipment or cleaning solutions. That may include gloves, goggles, and masks. Protective equipment will minimize exposure to chemicals and possible accidents. Always store the ultrasonic cleaner in a safe place far away from children and unauthorized persons.

Q & A

Q1. What is an ultrasonic transducer used for?

A1. Transducers transform energy from one type to another. An ultrasonic transducer converts electromagnetic or electric energy into sound waves. 25k ultrasonic transducers produce sound waves through a medium like air, liquid, or solid.

Q2. How many ultrasonic transducers should be used when cleaning?

A2. It depends on the generator used. Cleaners built with multiple transducers have them working in harmony to produce ultrasonic waves. That makes for even wave distribution and more cleaning power. So there's no limit on the number of transducers to use as long as they go with the generator. Just note that using an excessive number of transducers is not favored since they may interfere with one another.

Q3. How does an ultrasonic cleaner work with transducers?

A3. An ultrasonic cleaner works by generating sound waves through transducers fixed to its tank bottom. They create tiny bubbles in the cleaning liquid by emitting high-frequency energy. Bubbles collapse with great force after growing a certain size. It's called cavitation. Its force cleans the filth inside and outside the items. When the bubbles collapse, they release shock waves that rinse off the residue stuck in hard-to-reach spots.

Q4. How effective are ultrasonic cleaners?

A4. Ultrasonic cleaners handle tasks that are impossible to achieve by hand or with ordinary tools. Some have as few as two transducers, but most have four, eight, twelve, or twenty, packed to the brim with cleaning power. Bubbles as small as a tenth of a millimeter power through the junk, leaving it almost sparkling. They tackle everything from automotive engine components to dental instruments and jewelry with stubborn grime.
