Electromagnetic Ultrasonic Thickness Gauge

Product Introduction

1. Ultra-portable and reliable AIR new portable electromagnetic ultrasonic thickness gauge, capable of quickly and accurately measuring the wall thickness of steel pipes, aluminum plates, and other metal-made tubes, plates, bars, and other metal products, without the need for couplant or surface cleaning.

2. Measurement can be conducted through a non-conductive coating layer not exceeding 4mm (scale, rust, salt deposits, etc.).

3. Sound waves are directly formed in the measurement object with the assistance of an electromagnetic converter, unaffected by the environmental impact of non-metallic coatings. Therefore, the electromagnetic ultrasonic thickness gauge possesses the unique ability to penetrate complex types of coatings (such as loose rust, poor conductivity in high-frequency coatings, coatings with poor adhesion, etc.), allowing for the measurement of metal thicknesses that conventional ultrasonic thickness gauges cannot achieve.

4. The electromagnetic ultrasonic thickness gauge AIR can operate independently just like using an Android system to connect a tablet computer, without the need for coupling agent. The price of the electromagnetic ultrasonic thickness gauge is available, and you can see the actual radio signals on the screen in thickness gauge or flaw detector mode.

Eddy Current Ultrasonic Thickness Gauge

A thickness gauge is a compact, portable measuring instrument with precise measurement accuracy and range, and its fine craftsmanship has always made it our preferred choice for thickness measurement. Without the need for coupling agents, the thickness gauge can measure the dry film thickness of various textiles, rubber, plastics, metal foil strips, cardboard, wood panels, leather, and paint coatings, among others, with a wide variety of options, making it widely used by us.

Ultrasonic thickness gauges are categorized by their working principle, including resonance method, interference method, and pulse reflection method. Since the pulse reflection method does not involve resonance mechanisms, it does not require a coupling agent for electromagnetic ultrasonic thickness gauges, and is not closely related to the smoothness of the surface being measured. Therefore, ultrasonic pulse thickness gauges are a popular choice among users.

Electromagnetic Ultrasonic Thickness Gauge

When the magnetic lines produced by the magnet are perpendicular to the metal surface, the eddy currents are subjected to forces parallel to the metal surface, resulting in ultrasonic shear waves perpendicular to the applied forces.

When the magnetic lines are parallel to the metal surface, eddy currents are subjected to repeated force actions perpendicular to the metal surface, resulting in ultrasonic longitudinal waves in the direction of the force.

If the high-frequency coil is shaped into a snake pattern, with the current directions of adjacent sections of the winding opposite, and the spacing equal to half the wavelength, Rayleigh waves will be generated on the specimen's surface. The excited ultrasonic signal reflects and refracts off the surface of the test piece, and the echo signal is received by the receiving instrument. The receiving principle is the inverse process of electromagnetic ultrasonic excitation, converting mechanical energy into electrical energy.

Utilize a supervisory computer to denoise and analyze echo signals, determine if the inspected workpiece has any defects, and realize the detection process.
