Checks the sum of all the properties of the test object
Quick and cheap testing method (real-time)
Compact testing without any additional equipment, directly good / bad statement
Flexible installation, easy configuration
Utilisation even in rough industrial environments (IP67)
|
Magnetic particle inspection
Magnetically conductive components
Fault detection can be changed by false indications (magnetic stray fields of surface structures are only partially documentable)
Multistage, heavy automatable method of cleaning supplies and material consumption |
X-ray CT
Internal, inaccessible complex geometries
For fissures only specifically applicable (fault location must be known)
Equipment-and time-consuming process
Radiation hazards and high training costs |
Optical systems
External or easily accessible internal surface
Susceptible to dirt and humidity
Reduced measuring accuracy at shiny surfaces or changing light conditions
Reduced cycle times / additional equipment needed
|
Eddy current
Rotationally symmetrical inner and outer surfaces (usually rod material)
Flat surfaces
Low depth of penetration + low range
Several test channels for different types of faults and orientations of fissures
