COMPARISON OF X-RAY VS. MAGNETIC
Feature
Data display
Limitations
User friendliness
Breakage detection
Detection of integrated mesh, breaker, loop etc.
Detection of movement of steel cords in splice
Reliability
Maintenance
Clear and real digital photograph, very intuitive, software can automatically detect and identify all splices and damages.
No limitation from hardware, can detect all deficiencies of steel cords, splices and carcass. Detects holes, ripping, foreign objects, edge damage, insufficient cleaning, thickness change, etc.
Very easy to use, no special training needed.
Highly accurate, partial damage to a cord can be seen clearly.
Yes
Length determination of cord damage and movement inside a splice.
Highly reliable, proven technology.
Simple.
Analog wave signals or simulated internal steel cord imaging map, not intuitive, inaccurate. Requires trained personnel to interpret.
Limited to steel cords only. Cannot detect anything else.
Difficult to use, professional training needed to interpret inspection result.
Not very accurate. It can pick up broken cords, rusted cords, and splice disintegration, but cannot tell damage details, only a total.
Cannot differentiate steel cords from metal mesh or inserts.
Only total determination of cord damage and of volume changes inside a splice.
Not very reliable, vulnerable to environmental interferences.
Simple.
Splice detection
Splice recognition (identify each splice)
Determination of exact length of cord movement in splice
Broken cords
Broken strands
Partial corrosion of each cord
Misaligned cords
Belt speed monitoring
Foreign metal objects
Protruding objects
Edge damage
Ripping
Material build-up
Cord pitch
Belt width
Mistracking
Grooves in belt covers
