Because the ferromagnetic material can induce certain current value in alternating magnetic field, so current valuesinduced from different hardness of workpiece and workpiece with inner cracks on the surface are not the same in a uniform magnetic field emitted by our probe.The working principle of STY-2S Dual-Line Four-Channel Material Automatic Nondestructive Separator is that, separator induced the current of workpiece from probe by measuring the same specification of workpiece and compared it with the current induced from the same specification of standard sample, then displayed it in form of magnetic flux on the computer screen, so as to separate the material of the same specification of workpiece to be measured.

(1) Nondestructive testing, no trace will be left on workpiece after testing, avoid crack may be destroyed while using the traditional test method.
(2) Shape of surface state of workpiece and wide adaptability, generally no special requirements for the surface roughness of the workpiece.
(3)Instrument adopts the principle of electromagnetic induction, which adopts the method of comparing the workpiece to be measured with the standard sample to indirectly detect the workpiece quality.
(4) Multi-usage. Instrument conducts flaw detection after detecting the material of workpiece. If the material is found to be hardness unqualified, then flaw detection is no need any further.
(5)Machine will pick up the qualified(i.e., both material and flaw detection are qualified) and unqualified (i.e., material or flaw detection unqualified or both) workpiece to different tracks automatically.
(6)Instrument can respectively count the product detected by each channel.
(7)Instrument has the function of historical recordfor time and status query of product detected before.
(8)Separating machine controller dynamically displays the magnetic flux of workpiece with dot figure, the position of dot figure shows the corresponding test results in the computer.
(9)The main controlling instrument ofseparator has the setting function of upper and lower limits of the material and flaw detection, send corresponding blanking demand to blanking device in the region where dot figure cursor to be placed in.
(10)Instrument has the function of data analysis, which can conduct data analysis of workpiece has been tested and display in the form of curve wave.
(11)The operation ofinstrument is convenient and simple. Detection speed is fast,feeding and blanking time of dual-line in an hour without manual operation is 800-900 p/ h.
(12)100% detection of workpiece, meet the needs of detection of mass workpiece, to avoid the outflow of unqualified product in sampling inspection.
(13)It only needs to change matching probe for detection of different workpieces
(14)Surface state, specification and dimension of workpiece to bemeasured should be consistent, and certain processing error is allowablebut not exceed the related standards.
