Application of two measuring method :
●Magnetism method (F-probe)
The probe and the magnetic metal substrate will form a
closed magnetic circuit when probe contacting withthe
coating themagneticresistanceofclosedmagnetic circuit
varies due to the existing of non-magnetic coating.The
thickness of the coating can be measured through the
variation of magnetic resistance
Fig.1-1 principle of magnetism method
- ●Eddy current method (N-probe)
The high frequency alternating current generates an
electrsomagnetic field in probe coil; eddy current will
be
formed on metal substrate when the probe contacting
withcoating,andtheeddycurrent has aneffectof feedback
on the coil in probe. The thicknessof the coating can be
calculated through measuring the effect of feedback.
