Magnetic

 

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
