Low Cost Metal Ultrasonic Flaw Detector Crack Detectors For Welding Inspection

Low Cost Metal Ultrasonic Flaw Detector Crack Detectors For Welding Inspection  

This device is an integrated rotating magnetic field flaw detector designed for magnetic particle inspection of ferromagnetic materials. It effectively detects surface and near-surface defects with high sensitivity. It comes with a replaceable internal battery, effectively extending inspection time and requiring no external wiring. The compact size and high capacity of the electromagnet ensure approximately 8 hours of inspection time. Two batteries are included as standard.

The magnetic yoke offers strong lifting force and high detection sensitivity. Compared to traditional devices, the device is lightweight, and the ergonomically designed handle ensures comfortable operation. Its unique magnetic pole design enables surface and near-surface magnetic particle inspection of circumferential seams with an outer diameter of 80 mm and longitudinal seams larger than 100 mm.

The magnetic yoke supports both white light and ultraviolet light illumination, allowing for easy switching during operation. The device features overvoltage, overcurrent, overtemperature, and short-circuit protection to prevent damage in critical situations. The battery utilizes highly safe polymer batteries, and the battery protection circuit is well-designed, ensuring excellent battery protection and reliability.

Functional features::

1) Integrated power supply and yoke design allows for easy battery replacement.
2) Lightweight and compact, the unit is user-friendly.
3) The yoke supports flexible switching between UV and white light modes, adapting to varying magnetic particle inspection conditions.
4) High-performance LED lighting and imported high-irradiance UV lamps ensure high light intensity and a long service life.
5) Strong yoke lifting force, reaching up to 140N.
6) Constant magnetic design ensures that yoke lifting force remains unchanged regardless of battery level, maintaining excellent detection performance.
7) High detection sensitivity, allowing A1 to be observed during inspection. 15/100 sensitivity test strips clearly show magnetic traces.
8) Low power consumption: The standard two batteries provide enough power for 8 hours of on-site testing.
9) A battery indicator displays the remaining battery life in real time.
10) Multiple protections (overvoltage, overcurrent, overtemperature, and short-circuit) ensure safe and reliable operation.
11) Surge protection prevents backflow current from damaging the device during use.
12) A unique lighting delay design delays lighting for 10 seconds after magnetization, allowing for better observation of magnetic traces.
13) Utilizes a highly safe, explosion-proof lithium battery, ensuring battery safety during use.
14) The design is optimized for one-handed operation, with an ergonomic feel.
15) The entire device is impermeable to water to prevent magnetic suspension from seeping into the device and contaminating it, causing malfunctions.
