Measured Parameters

Main Features

1.Testing samples: soft magnetic ferrite, permalloy, amorphous ,nanocrystalline and iron powder core.
2.Test sample shapes: ring, E and U shapes.
3.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.
4.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%.
5.Magnetic induction obtained through digital integration of coil measuring voltage, magnetic induction peak value locked through digital feedback, magnetic induction lock precision 0.5%.
6.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.  
7.Measuring dynamic hysteresis loop through volammetry and digital integration can accurately measure dynamic magnetic characteristic parameters such as μa, δ, Pc, Br and Hc, and calculate μ, μ, μL, μR, Q and AL, etc.
8.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.
9.Powerful function of the software, the technical request to the testing staff is very low.

Software Functions

1. Operate under Windows7, complied to Windows software restricts, easy to operate.
2. Lock Bm (magnetic induction) and lock Hm (magnetic field) can be selected, fit for various measurement requirements.
3.  Automatic control, intelligent judgment, without user intervention all through the progress.
4.  Sampling waveform and instrument status under real-time monitoring, and can be stopped at any time.
5.  The effective sectional area and length of magnetic path of samples can be calculated according to the overall dimension of samples.
6.  System adopts database format, can directly print or output test result to Excel form.
7.  Various file management functions: data saving and deleting, remove all the data etc.        
8. Data files contain complete sampled data, sample parameters, instrument parameters and testing schemes, adopt text format, can be conveniently typed into other software.
9.  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
10. Multipoint cluster, can display B(H) magnetic hysteresis loop cluster, B(H) magnetization curve, μa(H) permeability curve and Ps(B) loss curve, and it can display coordinate message at every data point on the curve.
11. B(H) magnetization curve and Ps(B) damage curve measured under different conditions can be combined on one drawing for comparative analysis.
12. 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.
13. Print preview function, can conveniently regulate the size and edge distance of test report.
14. Test report can be directly printed, or generate JPG image file. JPG image file can be sent directly through E-mail, or saved into disk.
15. 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.
16. Optional multiple unit systems satisfies the application habits of different users.
