The Difference Between Electromagnetic Waves and Ultrasound
1. Modes of Propagation - The modes of propagation for electromagnetic waves and ultrasonic waves differ. Electromagnetic waves can propagate through a vacuum, thus making them suitable for space communication. In contrast, ultrasonic waves require a medium for transmission, such as water or human tissue, which is why the price of a metal shell electromagnetic ultrasonic thickness gauge is associated with these mediums.
2. Application Fields: There is a distinct difference in the application fields between electromagnetic waves and ultrasonic waves. Electromagnetic waves are used in communication, radio, radar, medical diagnosis and treatment, space exploration, and more. In contrast, ultrasonic waves are extensively employed in medical imaging, non-destructive testing, cleaning, and material processing.
In summary, the price of pen-type electromagnetic ultrasonic thickness gauges shows clear differences in terms of propagation methods and application fields between electromagnetic waves and ultrasonic waves.
Electromagnetic Ultrasonic Thickness Gauge
The central component of electromagnetic ultrasonic equipment is the electromagnetic ultrasonic transducer (EMAT), which generates ultrasonic waves by utilizing the Lorentz force, magnetostrictive effect, and magnetic force.
The EMAT consists of three parts: a magnet, a coil, and a specimen. The magnet is used to provide an external magnetic field, typically using a permanent magnet or an electromagnet. The advantage of a permanent magnet is its small size, while an electromagnet demagnetizes quickly, including DC electromagnets, AC electromagnets, or pulse electromagnets, etc.
Coils are used to generate high-frequency eddy currents, available in serpent, figure-8, and loop shapes. The specimen is an indispensable part of the electromagnetic ultrasonic testing system and must be an electrical or magnetic conductor. Electromagnetic ultrasonic in metal materials is produced by the Lorentz force, while in ferromagnetic materials, it is generally produced by the combined action of the Lorentz force and the magnetostrictive principle.
When high-frequency current flows through an inductive coil near the surface of a metal, the coil generates an alternating magnetic field, which also excites an eddy current electric field around it. The density of eddy currents in the metal surface depends on the magnetic field changes produced by the current in the coil, which is in the opposite direction to the high-frequency current within the coil and has the same frequency as the changes in the coil current.
Magnets provide an external static magnetic field on the metal surface. Under the influence of the external magnetic field, eddy currents generate a Lorentz force at the same frequency as the eddy current. The metal atoms vibrate back and forth under the Lorentz force, thus generating ultrasonic waves in the test piece. Price of electromagnetic ultrasonic thickness gauge.
Pulse current generates a pulse magnetic field that, when interacting with an external magnetic field, induces magnetostrictive effects. This causes the specimen to produce mechanical vibrations at the same frequency as the alternating magnetic field, enabling the generation of electromagnetic ultrasonic waves with different waveforms.
