Material sorting

Austenitic steel

Ferritic steel

Nickel silver

Bronze

 

Brass

Aluminium

 

Copper

Air

f = 3.4 kHz

 

C) Procedure

1. Balance in air!

2. Put the sensor consequently on the round blanks and record the signals best filling the XY-plane.

3. Adjust the phase so that the correspondence to the normalized impedance plane becomes obvious.

4. Demonstrate the automatic recognition of a defined material (use the traffic light)!

 

A) Job

Demonstrate the material sorting!

 

B) Utensils

1. Absolute probe

2. EddyCation BK3

 

 

D) Report

1. EddyCation report with the best result.

2. Draw the curve that would draw the point when continuously changing the conductivity of the material!

3. What material properties affect the conductivity and/or the magnetic permeability?

4. Discuss the limits of eddy current sorting!
