Silicon Steel Material Measurement System

Model: DX-2012M Silicon Steel Material Measurement System

DX-2012M Silicon Steel Material Measurement System

DX-2012M Silicon Steel Material Measurement System

Automatic measurement of the dynamic magnetic hysteresis loop of oriented and non-oriented silicon steel under the condition of 45Hz～1kHz, accurate measurement of the static magnetic characteristic parameters such as amplitude permeability μa, loss angle δ, specific total loss Ps, remanence Br and coercivity Hc. With special testing fixture, it can directly measure the silicon steel, permalloy, amorphous and nm crystal stator core and transformer core.

Windows measurement software applied simply. The product conforms to China National Standards GB/T 3655-2000, GB/T 13789-92 and international standard IEC 404-2, IEC 60404-3, 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

  1. Testing sample varieties: hot rolling, cold rolling silicon steel materials, permalloy, amorphous and nm crystal.
  2. Testing sample shapes: Ring, CD, Rect, EE and EI closing samples.
  3. Open circuit samples adopt Epstein Square to form closed magnetic circuit, it can also select sample silicon steel permeameter, such as SST30mm×300mm, SST500mm×500mm etc.
  4. Closing sample can be put under direct winding measurement, finished transformer can be also put under direct measurement.
  5. Sample (iron core), magnetizing coil (N1) and measuring coil (N2) form a no-load transformer.
  6. Power source and sampling amplifier put into a chassis which make the interface very simple: a RS232 interface connect to the computer, the second voltage signal connect to high speed A/D card.
  7. Adopt volammetry and digital integration to measure dynamic hysteresis loop, it can accurately measure dynamic magnetic characteristic parameters such as μa, δ, Ps, Br and Hc, etc.
  8. Automatic and continuous measurement up to 255 testing points, the testing time of every testing point is about 5 seconds, fixed-frequency, fixed Bm or fixed Hm optional in multipoint test.
  9. Powerful function of the software, the technical request to the testing staff is very low.
  10. Output is sine wave, output distortion is very low and nothing to do with the load, ensure the accuracy of the test result.
  11. Excitation power supply and current are both multi-range automatic output, it could automatically select the output range according to the test samples and number of turns, ensure the accuracy of the test result.
  12. Adopt 32-bit embedded high speed processor, with powerful function of data processing.
  13. Support the result-sorting, simple operation, well suitable for field measurement.
  14. Adopt size 320×240 big screen LCD which could show all kinds of waves, curves and test results.
  15. Support RS232 interface, which could connect with PC to be the test system (DX-2012SA Windows test software), with more function.

Software Features

  1. Operate under Windows 2000/XP ,Win7/8 operating systems, conform to Windows software specification, visual and simple operation.
  2. Full automatic control, intelligent identification, users' interventions are unnecessary in entire testing process.
  3. Sampling waveform and instrument status under real-time monitoring, and can be stopped at any time.
  4. The effective sectional area and length of magnetic path of samples can be calculated according to the overall dimension of samples.
  5. File system adopts database format, can directly print or output test result to Excel form.
  6. Powerful file management functions: data saving and deleting, remove all the data, etc.
  7. Data files contain complete sampled data, sample parameters, instrument parameters and testing schemes, adopt text format, can be conveniently typed into other software.
  8. 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. 
  9. Multipoint cluster, can display B(H) magnetic hysteresis cycle cluster, B(H) magnetization curve, μa(H) permeability curve and Ps(B) damage curve, and it can display coordinate message at every data point on the curve. 
  10. B(H) magnetization curve and Ps(B) damage curve measured under different conditions can be combined on one drawing for comparative analysis. 
  11. Set up upper and lower limits according to μa, Ps, Bm, Br, Hc and Hm, etc. Qualify test result and determine through the color of data table. 
  12. Support various models of printers, test report accurately match printer sheet.
  13. Print preview function, can conveniently regulate the size and edge distance of test report.
  14. Jest report can be directly printed, or generate JPG image file.
  15. JPG image file can be sent directly through E-mail, or saved into disk.
  16. Test reports contain complete curve diagrams, test results, test conditions and sample parameters.
  17. Both Chinese and English format can be adopted to facilitate adding user mark and enterprise name.
