Eddy Current (3)
Monitoring conductivity & permeability
determination of heat damage
cladding & plating thickness measurement
material sorting
heat treatment monitoring
material identification
factors consider for EC probes
material penetration requirement
sensitivity requirement
type of probe connection
probe & instrument impedance matching
probe size (small probe, penetrate less)
Advantage EC inspection
portable equipment
sensitive to small cracks and other defects
can inspect any complex shapes
probe doesnt need to contact the parts
disadvantage EC inspection
only conductive material
depth of penetration limited
check the reference standard
surface finish % roughness may interfere
equipment
instrumentation
probes
reference standard
conductivity measurement
measure elec conductivity at bell bronze casing at various point (evaluate uniformity)
