Magnet Force--For evaluation / analysis of magnet roll magnetic field for copier / facsimile--

Magnetic Characteristic Analysis
System Apparatus for Magnet Roll

●The principal feature of this apparatus development is research and development /performance test / quality control of magnet roll.
●3D direction (X-Y-Z) coincidence data import by 3D direction hall probe and gaussmeter is possible.
●Cover all necessary evaluation item and analysis features completely by exclusive
development software.
●Distinguished repetition reproducibility by very high machine accuracy●Adopt the high-performance gauss meter which developed exclusively for thisapparatus●Realize very high A/D conversion accuracy by our original noise suppression circuit

Magnet ForceProduct Outline
1. The magnet roll which can measure♦Measurement of magnet roll of various sizes is possibility by changing it for a jig corresponding to shaft diameter.
Maximum overall length (sleeve unit / shaft include)
360mm / 450mm
Sleeve shaft diameterφ5 ~ φ20
Magnet shaft diameterφ5 ~ φ14
Measurement diameterφ14 ~φ50
2. Maximum overall length
Maximum 400mm (Sleeve unit 360 + both ends 20mm)
3. The number of the poles which can measuremaximum 10 poles (asymmetry / symmetry)
4. Measurement circumferential direction points of one lap
You have two choices. (Both a and b, user-settable minimum angle pitch is 0.1 degree)a) Measure magnetism five points of arbitrary angles from origin angleb) Measure magnetism in range of arbitrary angle, and can set number of measurement point.
5. Measurement longer direction points
Arbitrary configuration between two points(user-settable minimum moving pitch is 0.1mm)

6. The direction that can measure Choice of 1D direction measurement / 2D direction measurement / 3D direction
measurement is possible on software.
♦If you select 3D direction measurement mode and use three gauss meter, simultaneous
measurement of 3D direction magnetic flux density is possibility by cross sectional
direction measurement / long distance direction measurement of magnet roll.
7. Gauss meter
Required specification of gauss meter will be separately discussed.
