Description

Technical Field

[0002] Magnetic flux leakage testing is a non-contact, non-destructive testing technique that identifies defects or anomalies in materials based on changes in magnetic fields. When a ferromagnetic material is magnetized, if there are defects on or near its surface, a magnetic flux leakage field will be formed at that location. By detecting changes in the magnetic flux leakage field, these defects can be discovered. Continuous monitoring and processing devices are used to process magnetic flux leakage signals from the testing of metallic materials and components.

[0003] Magnetic flux leakage (MFL) testing, as an efficient non-destructive testing method, determines the defect status of ferromagnetic materials by detecting the magnetic field caused by surface and near-surface defects. However, existing MFL monitoring and processing devices have many problems that limit the accuracy and efficiency of detection. In the field of MFL monitoring, existing monitoring and processing devices have some issues when connecting and assembling MFL sensors. The connection methods of traditional devices may not be flexible enough to adapt to different monitoring scenarios and sensor layout requirements. For example, some devices have fixed sensor connection structures, which makes sensor installation inconvenient and affects the monitoring effect, thus failing to meet the requirements for continuous and accurate monitoring and processing of MFL signals.
