R

AC HYSTERESIS GRAPH PLOTTER MODEL NO.- ACM- HGP-2215 Under continuous frequency of 1 kHz to 500 kHz, automatic measurement of magnetic hysteresis loop of the soft magnetic materials such as silicon steel, precision alloy, non-crystal and ferrite, accurate measurement on the dynamic magnetic characteristic parameters such as amplitude permeability, loss angle loss iron Pc, remanence Br and coercivity Hc Windows measurement software applied simply. It conforms to National Standards GB 5026-85, GB 3658-90, GB/T 9632.1-2002, GB/T 19346-2003, industry standard SJ/T 1028191 and international standard IEC 60367-1, IEC 60404-6.The controlling of computer and A/D sampling replace the traditional analog bridge, frequency meter, ammeter, voltage meter, power meter, the whole testing process is automatic completed.

General Features Ÿ Testing sample varieties: soft magnetic ferrite, permalloy, amorphous and nano crystal. Ÿ Test sample shapes: toroid, E and U shapes. Ÿ Test samples with closed magnetic circuit can be directly winded and measured on samples. Magnetizing

coil (N1) and measuring coil (N2) form a no-load transformer. Ÿ Non-inductive resistance connected on magnetizing coil loop to determine magnetizing current and

magnetic field intensity through the measurement of pressure drop on non inductive resistance, magnetic field peak value can be locked through digital feedback, magnetic field lock precision 0.5%. Ÿ Magnetic induction obtained through

digital integration of coil measuring voltage, magnetic induction peak value locked through digital feedback, magnetic induction lock precision 0.5%.

Ÿ Power source and sampling amplifier integrated into a casing with simple interface: one RS232 interface

connected to the computer, two way voltage alarm connected to high speed A/D card. Ÿ Different power sources can be selected according to different test requirements: 1 kHz ~ 300 kHz or 500

kHz, 5 kHz or 10 kHz ~ 100 kHz or other frequency ranges customized. Ÿ Measuring dynamic hysteresis loop through volammetry and digital integration can accurately measure

dynamic magnetic characteristic parameters such as µa, d, Pc, Br and Hc, and calculate µ', µ'', µL, µR, Q and AL, etc. Ÿ Automatic and continuous measurement up to 255 testing points, the testing time of every testing point is

about 12 seconds, fixed-frequency or fixed Bm optional in multipoint test. Ÿ Powerful function of the software, the technical request to the testing staff is very low. Ÿ Operate under Windows 95/98, Windows 2000/XP operating systems, conform to Windows software

specification, visual and simple operation. Ÿ Full automatic control, intelligent identification, users' interventions are unnecessary in the whole testing

process. Ÿ Sampling waveform and instrument status under real-time monitoring, and can be stopped at any time. Ÿ The effective sectional area and length of magnetic path of samples can be calculated according to the

overall dimension of samples. Ÿ File system adopts database format, can directly print or output test result to Excel form. Ÿ Powerful file management functions: data saving and deleting, remove all the data etc. Ÿ Data files contain complete sampled data, sample parameters, instrument parameters and testing

schemes, adopt text format, can be conveniently typed into other software. Ÿ Display I(t), U(t) and B(t) sampling waveform and B(H) hysteresis loop, and coordinate message at every

data point on the curve. Ÿ Multipoint cluster, can display B(H) magnetic hysteresis cycle cluster, B(H) magnetization curve,

Ã,¼a(H) permeability curve, ua(F) permeability curve, Ps(B) damage curve and Ps(F) damage curve, and can display coordinate message at every data point on the curve.

Ÿ B(H) magnetization curve, ua(F) permeability curve, Ps(B) damage curve and Ps(F) damage curve

measured under different conditions can be combined on one drawing for comparative analysis. Ÿ Set up upper and lower limits according to ua, Ps, Bm, Br, Hc and Hm, etc. Qualify test result and

determine through the color of data table. Ÿ Support various models of printers, test report accurately match printer sheet. Ÿ Print preview function, it can conveniently regulate the size and edge distance of test report. Ÿ Test report can be directly printed, or generate JPG image file. Ÿ JPG image file can be sent directly through E-mail, or saved into disk. Ÿ Test reports contain complete curve diagrams, test results, test conditions and sample parameters. Both

Chinese and English format can be adopted to facilitate adding user mark and enterprise name Ÿ Multiple unit systems optional to satisfy the application habits of different users.

System Specifications Adopt volammetry to measure loss Ps and amplitude permeability µa and loss angle , when test frequency is 50 kHz, conduct test on ferrite circular ring sample with standard size (d1 = 40 mm, d2 = 32 mm, h = 6 ~ 10 mm), technical indices as follows:
