BH Tracer Hysteresis Graph Test System

The DX-2012H DC Hysteresis Graph Test System conforms to China National Standards GB/T 3217-92, GB 11209-89 and international standard IEC 404-5.

Adopt ATS structure, users can customize different configurations as required: According to the intrinsic and size of the measured sample to decide the electromagnetic size and corresponding testing power supply; Select different measuring coils and probes according to the option of measuring method. Decide to whether choose a fixture in accordance with the sample shape. Decide to whether select heating installation or not according to the test requirement.

General Features of DX-2012H DC Hysteresis Graph Test System

1. Automatic measurement on saturation hysteresis loop and magnetic characteristic parameters of generally permanent-magnet material such as Ferrite, Rubber & Plastic Magnet and AlNiCo, etc.: Js, Br, HcB, HcJ, (BH)max and µrec.

2. Automatic measurement on demagnetization curve and magnetic characteristic parameters of rare earth permanent-magnet materials such as NdFeB and SmCo, etc. at the second quadrant: Br, HcB, HcJ, Hk(H90) and (BH)max.

3. Test sample shapes: circular ring, round cake, square, tile and other irregular shapes.

4. Adopt B coil + fluxmeter to measure magnetic induction, zero shift of integrator can be self-corrected through software.

5. Adopt J coil + fluxmeter to measure magnetical polarization, the remnant coil area of J coil can be automatically compensated through software.

6. Magnetic field intensity can be measured with a Hall magnetometer, and nonlinear error of the Hall probe can be corrected through software, within the 0 ~ 2.4T range, nonlinear error can be controlled within±0.2%.

7. Adopt H coil + fluxmeter to measure magnetic field intensity, Hall magnetometer is only used to indicate the zero point of the magnetic field so as to thoroughly eliminate the nonlinear error of the hall probe.

8. The optimal range of field voltage, fluxmeter and magnetometer can be automatically set up.

9. Magnetization, testing and demagnetization of the general permanent magnetic sample completed at one time, time set up 20 seconds ~ 60 seconds.

10. Rare earth permanent magnetic samples need saturation magnetizing before testing, testing time of 60 seconds ~ 120 seconds.

11. The sample after testing is in demagnetization or magnetizing status, freely selected by users.

12. Select the heating head and temperature controller to detect magnetic characteristics of Ferrite, AlNiCo and rare earth material under high temperature (maximal 220°C).

13. Select a shoe jig for direct measurement on the magnetic shoe.
