The NCS-MMTI200 steel plate hard spot micro-magnetic NDT trolley system, developed by NCS Testing Technology, has already been put into service at a major domestic steel plant.
Uneven hardness in steel plates leads to unstable strength and reduced load-bearing capacity. Conventional methods are neither fast nor capable of full-coverage hardness inspection. To solve this problem, our second-generation trolley system provides non‑destructive quantitative evaluation of steel plate surface hardness.
Ease of Operation
Steel body with lithium battery power supply – reasonable mechanical structure
Total weight: 50 kg
Maximum pushing speed: 1 m/s
Single charge operation: up to 8 hours
Easy to operate, flexible to move, and adapts to plates of different sizes and shapes – lowers skill requirements and training costs.
High Inspection Accuracy
Staggered probe arrangement: 8 probe groups / 32 channels
Inspection width: 320 mm (can be increased or reduced by adding/removing probes per customer request)
Laser alignment device prevents missing any area of the plate.
Strong Data Processing & Analysis
Calibrate the reference hardness value before inspection – values beyond a defined range are flagged as excessive hardness.
Inspected areas are imaged on a tablet in real time. Red areas indicate excessive hardness, and a side audible‑visual alarm is triggered.
User‑friendly interface with powerful software – fast analysis of inspection data, images saved for precise location of hard spots.
Offline Inspection Capability
Equipped with an offline inspection module and offline probe for POD testing – flexible inspection of steel plate samples.
Robust & Reliable in Industrial Environments
Hardware uses high‑quality, high‑stability materials and components.
Software has been extensively tested and optimized on site.
Strong anti‑interference performance – reduces environmental errors, ensures consistent and reliable results.
Customizable Modes
The hard spot inspection system can be tailored to your needs:
Trolley inspection mode (as described above)
Gantry scanning mode – steel plate fixed, gantry automatically scans
Fully automatic scanning system – steel plate moves linearly, probes fixed for full coverage.
With the NCS-MMTI200, you get stable, efficient, and accurate quality assurance for your steel plate production.
