KEY: good or positive icon advantage, bad disadvantage

blau icon Acoustic testing

good, positive, vorteil icon Checks the sum of all the properties of the test object
good, positive, vorteil icon Quick and cheap testing method (real-time)
good, positive, vorteil icon Compact testing without any additional equipment, directly good / bad statement
good, positive, vorteil icon Flexible installation, easy configuration
good, positive, vorteil icon Utilisation even in rough industrial environments (IP67)


dunkelblau iconMagnetic particle inspection

good, positive, vorteil iconMagnetically conductive components
bad, negative, nachteil iconFault detection can be changed by false indications                                                      (magnetic stray fields of surface structures are only partially documentable)
bad, negative, nachteil iconMultistage, heavy automatable method of cleaning supplies and material                      consumption

pink iconX-ray CT

good, positive, vorteil icon Internal, inaccessible complex geometries
bad, negative, nachteil icon For fissures only specifically applicable (fault location must be known)
bad, negative, nachteil icon Equipment-and time-consuming process
bad, negative, nachteil iconRadiation hazards and high training costs

gelb icon Optical systems

good, positive, vorteil iconExternal or easily accessible internal surface
bad, negative, nachteil iconSusceptible to dirt and humidity
bad, negative, nachteil iconReduced measuring accuracy at shiny surfaces or changing light conditions
bad, negative, nachteil icon Reduced cycle times / additional equipment needed

orange icon Eddy current

good, positive, vorteil iconRotationally symmetrical inner and outer surfaces (usually rod material)
good, positive, vorteil icon Flat surfaces
bad, negative, nachteil icon Low depth of penetration + low range
bad, negative, nachteil iconSeveral test channels for different types of faults and orientations of fissures
