System comparison

There are some systems on the market, each covering parts of the capturing spectrum of a CBGuard Life Extender X6. Devices which recognize the condition of steel cables in the conveyor belt with magnetic fields are most prominent. However, they have significant disadvantages against radiographic systems such as CBGuard. The following comparison makes this clear.

Data representation

From each steel cord and splice, CBGuard provides a clear photographic presentation, as known from health diagnosis or baggage controls at airports. Changes to a steel cord or a splice are processed automatically. The condition of all steel cords and all splices as well as the location of the cables can be displayed via X-ray photographs of individual belt sections or an X-ray video of the entire belt. These recordings are constantly generated by the CBGuard.
Magnetic resonance methods only display coarse diagrams of the steel cords and the splices which must be interpreted by persons skilled in the art.

Defect recognition

CBGuard not only detects and processes damage to each cable as well as delamination between the cables and the core rubber but also unusual movements of the cables in a splice. This allows CBGuard to intervene before a splice opens. CBGuard identifies each individual splice.
Magnetic methods can not detect any adhesion deficiencies / blisters, nor any cord movements.

Identification of reinforcements

Transverse reinforcements or rip detection sensor loops, often integrated in steel cord conveyor belts, are recognized and displayed by CBGuard.
Magnetic methods can not recognize such passive protection systems differentiated; they can even lead to distortion of the cable recordings.

Data reconciliation

CBGuard permanently compares all parameters of the conveyor belt with its setpoints and its state of the last cycle. Any deviations are automatically signaled and processed.
Magnetic methods do not provide these functions.

Condition of the entire belt

The detection of the condition of a conveyor belt by CBGuard is not restricted to the steel cords, but rather captures its entire integrity. CBGuard identifies and processes any changes such as belt rips, foreign bodies, edge damage, caking, holes, grooves, notches, delaminations, mistracking, belt speed, etc. The exact belt thickness is also measured.
Magnetic systems can not detect these deficiencies.

User-friendliness

The CBGuard scanner comes as a compact unit that is easy to install. The scanner is almost maintenance-free, because there are neither moving parts nor contact with the conveyor belt.
Magnetic systems are still somewhat smaller, but are subject to numerous environmental influences.

Safety

CBGuard does not contain radionuclides, but generates the X-rays from electricity. Without electricity there is no X-ray radiation. The housing is insulated. In addition, several measures ensure that unauthorized persons are not allowed access. Outside of the safety zone the radiation intensity corresponds to the normal ambient radiation. 
Magnetic systems are also safe.
