crack Inspection Lamp LUYOR-3124
LUYOR-3124 Stationary UV-A-LED-High-Performance Wide Area Floodlight with System-Monitoring, the Real Substitute for 400W Halogen UV-A-Flood-Lamps
The modern follower of the well-known 400Watt stationary flood lamps without compromises. the LUYOR-3124 emits a very homogeneous UV-A-Radiation, due to the high-end LED-Technolgy is has a low power consumption and is really quite. compared to bulb-based lamps UV-LED-Sources offer much advantages in practice.
This lamps combines many different skills in one tool:
• very uniform UV-A-Distribution
• Minimum Working Distance of only 10cm
• finely dimmable between 10 und 2.000 Lux (measured at a distance of 38 cm (15 in.))
• No reflections, nor on shining surfaces
• high quality of the visible light, Color Rendering Index >75
• many accessories available to customize this lamp easily for all usage and hand-free working)

Magnetic Particle Crack Detection
Cracks in cast iron or steel components, which can be magnetised, can be found using magnetic particle inspection. The component in question is temporarily magnetised using a permanent or electro magnet and then small iron oxide particles in dry powder form or in a solution in water or kerosene are then sprayed or brushed on. Prior to this the component must be thoroughly cleaned and free from oil grease and dirt
Any crack in the component disrupts the magnetic field and attracts the iron particles which shows up the crack. To assist with the detection the particles may be dyed in bright colours or the component painted with a white paint.
However the most sensitive method is to use particles treated with a fluorescent dye and then view the results using an ultra violet lamp under low light conditions.
It may be necessary to rotate the magnetic field through 90° to allow the crack to show up. This is because the lines of magnetic force must cross the crack at an angle for it to show up.
Afterwards the component should be demagnetised especially if it is a bearing journal or thrust collar This is because of the danger of wear particles being attracted to the surface after the inspection. Components that are to undergo weld repair after a crack is detected (e.g. cylinder head) must also be demagnetised as residual magnetic fields can interfere with welding repairs.
