Device, in addition to conducting wire is exposed, clutch component, magnet, magnetoelectricity sensing assembly and integrated conversion module are respectively positioned on inside, it can be as passing
System spindle work like that, also can On-line sampling system spindle revolving speed and consumption power, and by measurement data judgement spindle be
It is no to be in normal operating conditions.The present invention maintains existing plug mounting means, working method and the fixed form of traditional spindle,
Tradition spinning spindle blade is changed into sensing guide element, traditional bolster is transformed by the advantages of remaining traditional spindle working method
At sensing bolster, in a manner of the plug of traditional spindle, the clutch of spindle blade and magnetoelectricity sensing assembly is realized by clutch component, simultaneously
Without the precision drive mechanical mechanism of traditional spindle and oil lubrication mechanism inside bolster；When spindle blade as tube rotates together
When, the rotation of spindle blade and clutch key connection therefore spindle blade necessarily will drive the synchronized rotation of clutch key, be fixed on clutch key end
The also inevitable rotation synchronized therewith of the magnet at place, and magnet is identical as the motion state of spindle blade.In short, the present invention has structure clear
It is clear, performance is stable, high sensitivity, can in the presence of a harsh environment Reusability, can mass production, at low cost, the service life is long, does not change
The advantages of traditional spindle existing working method.
