Due to ferromagnetic substance can sense certain current value in alternating magnetic field.the probe sends a uniform magnetic field to identical specification with different hardness and workpiece with flaw on the surface will sense different current value. STY-2 double line hardness、flaw detector nondestructive sorting machine senses current value in probe from identical specification exemplar and compare then display on the screen by magnetic flux by measuring induced current in probe of identical dimension workpiece and identical specification standard exemplar so as to distinguish the advantages and disadvantages of hardness flaw of detected identical specification workpiece.

1、Nondestructive detection, there is no damage left on the surface of workpiece,avoid traditional solution from destroying detection
2、It it suitable for a lot of state of workpiece surface and shape,normally it has no special requirement on the surface of workpiece
3、The instrument adopts the electromagnetic induction principle ,taking advantage of detected workpiece and standard exemplar to detect the quality of workpieces
4、One machine with multifunction.instrument will detect workpiece after hardness detecting on workpieces,, when hardness detecting there are
5、When detected workpiece are qualified and unqualified,the machine will take them out to different transfer pathway manually
6、The instrument can count on products respectively on detected products of every channel
7、The instrument possesses history memory,so it can search time state of detected products
8、The main control machine of sorting machine uses dynamic display of dot figure detected magnetic flux, wherever the dot figure on,the results of detecting will be displayed on the computer
9、The main control instrument of sorting machine equipped with upper limit and lower limit of hardness and flaw detection,when the dot figure cursor is located in some area then give relative instruction
10、The instrument has data analysis function ,and do data analysis on detected workpiece and be showed by the form of curvelets
11、Instrument operating is simple .detecting speed is fast ,double lines one hour and exclude manual time is 800-900pieces one hour
12、Dodetection on workpiece,satisfying a mount of detecting workpiece,and avoid unqualified products outflow from sampling
13、It just needs to change relative probe to detect different workpiece so as to satisfy detecting needs
14、The surface stats of detected workpiece is the same with identical
dimension、it also allowed certain machine error ,however,the machine
error can not exceed relative standard
