Metal Stress Concentration and Crack Detection Composite Instrument

Product Overview

The 【3026 Metal Stress Concentration and Crack Detection Composite Instrument (2-in-1)】 is integrated with the latest technologies: magnetic memory technology and pulsed eddy current testing technology. According to detection requirements, the instrument automatically changes and controls the probe's scanning sequence, frequency, intensity, and filtering parameters through electronic switching technology. It allows users to change probes and scanning methods based on detection purposes and requirements. The instrument is compact (palm-sized) and powerful: it can not only provide early warnings of metal stress concentration but also quickly and accurately detect defects in any direction of metal components. Its highest detection capability can identify tiny crack defects under multi-layer metal structures, surpassing the well-known medium coupling issues in the traditional NDT industry.

Save your resources, improve detection efficiency, and achieve comprehensive inspection of equipment (covering over 97% of metal conductor components).

n Capable of early diagnosis of the fatigue index and damage degree of 'metal components', with the ability to freely switch between stress concentration detection and metal crack detection.               

n Features the efficacy of 'internal defect detection in multi-layer structures', capable of detecting tiny defects under multi-layer metal structures. Adapts to various forms of detection needs.               

n Can be used for detecting cracks in welds and base materials with anti-corrosion layers, as well as measuring crack depth;

n Can quickly detect stress concentration, surface, and sub-surface defects in in-service equipment caused by material discontinuities (defects).               

n Applicable for testing boiler pressure vessels, pipelines, blades, landing gear, bearings, railway tracks, gears, locomotive wheel sets, welded parts, and other conductive metal components.

n Provides data analysis and data transmission software CD, allowing in-depth post-processing of data on a computer, and can output Dr(SCZ) fatigue index and crack quantification, etc.

The 3026 Metal Stress Concentration and Crack Detection Composite Instrument is a dual-purpose device that can connect to stress concentration sensors and pulsed eddy current crack identification sensors, enabling stress concentration detection or pulsed eddy current crack detection through simple electronic switching.
