Reference Magnets VM 5

Reference magnets VM 5 are primarily suitable to calibrate axial probes. These can have a diameter of up to 6 mm. A side slit allows additionally testing of transverse Hall probes. The homogeneity of the VM 5 is extraordinarily good for an axial reference magnet, so that the center gap field strength can be given with an uncertainty of approximately 0.4 %.

Axial acceptance Transverse acceptance Field strength Flux density 6 mm 5 mm x 10 mm max. 80 kA/m (1 kOe) 0.1 Tesla (1 kGauss) Other flux densities in the range of about 0.01 T to 0.1 T (0.1 kG to 1 kG) are available on request, but require longer lead times. Diameter: 68 mm Height: 55 mm Weight: approx. 1 kg A proprietary calibration certificate, which documents traceability of calibration to national standards, is issued free of charge on purchase. A calibration can alternately be carried out in our DKD accredited calibration laboratory. Periodic recalibration is recommended and can of course also be performed by our laboratory. To preserve the calibration accuracy over a long time, we recommend observing the following precautions:

?

Keep reference magnets away from magnetic fields.

?

Do not insert magnetic or magnetizable parts, for example tools, into the air gap.

?

Avoid magnetic pollution in the air gap.

?

Store the reference magnets in a safe place and take them out only for the calibration of your measuring instruments.

?

Do not expose the reference magnets to mechanical shock or extreme temperatures. Due to continuous product improvements specifications are subject to change without notice. MAGNET-PHYSIK Dr. Steingroever GmbH MAGNET-PHYSICS Inc.
