Abstract
The utility model relates to a quick measurer especially suitable for measuring the magnetic susceptibility performance of soft magnetic materials, which belongs to the performance measurement field of magnetic materials. The measurer is formed by the mode that two identical solenoid coils are arranged in a shielding cover; a measuring probe is arranged between the two coils which are connected in series and contrarily connected. When the two coils are electrified, magnetic fields emitted by the two coils are positively negatively offset between the two coils to generate zero magnetic field; the probe installed herein can measure the change in a space magnetic field in the shielding cover because a sample is added; the performance parameters of magnetic susceptibility, etc. of the sample can be figured out. The utility model has the characteristics of simple and reasonable structure, convenient and easy sample preparation, simple operation, high measuring speed, low manufacturing cost, etc.
Description
The utility model device belongs to the performance measurement field of magnetic material.Be specially adapted to the rapid measurement device of soft magnetic material magnetic susceptibility performance.
In the prior art, for the magnetic susceptibility of measuring soft magnetic material static state, the general method that is adopted is closed circuit ballistic method, the operation of this method is the measuring samples that soft magnetic material is prepared into ring-type earlier, the primary and secondary lead that is wound with the regulation number of turn then on the ring-type sample is for measuring usefulness, and the effect of its measuring operation is trouble.Also have adopting the vibrating sample magnetometer of being furnished with Helmholtz coils to measure the magnetic susceptibility of soft magnetic material in addition, but adopt the measured sample of this device, must be to be prepared into small-sizedly, and shape need is very strict.Most importantly the cost of this device is too high for it, and about 12-15 ten thousand U.S. dollars of vibrating sample magnetometer of import.Above-mentioned two kinds of common defects that measurement mechanism brought have the complex-shaped of sample, the preparation difficulty, and also measuring operation is time-consuming, so can not reach the effect of quick measurement.
The purpose of this utility model is to propose a kind of project organization advantages of simple, and is convenient to operation, and the measurement mechanism of the measurement soft magnetic material magnetic susceptibility of cost economy.
According to purpose of the present invention, the composition of the quick measurement soft magnetic material magnetic susceptibility measurement device that we proposed can be described with reference to the accompanying drawings.This accompanying drawing is the structural profile synoptic diagram of the utility model soft magnetic material rapid measurement device, and in the accompanying drawings, 1 is magnetic shielding cover, 2 for measuring solenoid coil, and 3 are the calibration solenoid coil, and 4 is sample transfer bar, 5 is sample, and 6 are the flux-gate magnetometer probe, and 7 is the strong magnetic meter of fluxgate, 8 is direct supply, and 9 are Hall gaussmeter probe, and 10 is the Hall gaussmeter, 11 is brace table, 12 is tuner, and 13 is data collection processor, and γ is the distance between sample and the flux-gate magnetometer probe.Can find out by accompanying drawing, the measurement mechanism of the quick soft magnetic material magnetic susceptibility of the utility model is by measuring casing and power supply, data acquisition and handle this two parts and form, it is characterized in that being equipped with on the brace table 11 in magnetic shielding cover 1 two physical dimensions and the equal solenoid coil 2 and 3 of coil turn, the strong magnetic meter probe 6 of fluxgate is housed between solenoid coil 2 and 3, and be connected with flux-gate magnetometer 7 by lead, put the tuner 12 that the coil cover is laterally moved along central axis is housed measuring solenoid coil, in measuring solenoid coil 2 along on the sample transfer bar 4 at axis centre place sample 5 being housed, in the calibration solenoid coil, the Hall gaussmeter is housed and pops one's head in 9 along the axis centre place, and link to each other with Hall gaussmeter 10 by lead, solenoid coil 2, should be the series connection reversal connection between 3, and the leading-out terminal that externally connects should link with the both positive and negative polarity of direct supply 8, and flux-gate magnetometer and Hall gaussmeter 10 should link with data collection processor 13 respectively.
The given quick measurement soft magnetic material magnetic susceptibility measurement device of the utility model device is work like this in implementing measurement.Before in measuring solenoid coil 2, placing samples 5 by sample transfer bar 4, at first give solenoid coil 2 by direct supply 8,3 logical electric currents, in solenoid coil 2 and 3, respectively produce the dc fields that an intensity equates this moment, but because solenoid coil 2 and 3 is series connection reversal connections, so the direction in the magnetic field that they produce is opposite, can measure the size of axial magnetic field in the coil by hall probe 9 and gaussmeter 10, simultaneously because coil 2 is opposite with 3 magnetic directions that produce, in the positive and negative magnetic field cancellation of coil 2 and 3 centre positions, produce one zero magnetic fields, should measure with flux-gate magnetometer probe 6 in zero magnetic field, when flux-gate magnetometer 7 is non-vanishing, illustrate that probe 6 placement location is not in the centre of coil 2 and 3, position by tuner fine setting line 2, can reach the purpose of producing zero magnetic field, after mixing up zero magnetic field, by sample transfer bar 4 sample 5 is placed into center in the coil 2, the magnetic field magnetisation that this moment, sample 5 was produced by coil 2, after being magnetized, sample 5 produces the magnetic moment of certain intensity, this magnetic moment produces magnetic field in the space, in probe 6 position with probe 6 and flux-gate magnetometer 7 can measure sample 5 relative pop one's head in 6 when being r the size in the magnetic field that produces, but according to this magnetic field counterplot calculate sample 5 be magnetized the back magnetic moment that produces size, the intensity of the magnetizing field that produces according to this magnetic moment value and coil 2 can calculate the magnetic susceptibility of sample 5 under this magnetizing field, can gather automatically and handle measurement data by data acquisition processing system 13, realize the robotization of measuring.
The utility model has the structural design advantages of simple compared with prior art, not only make easily, and manufacturing cost is also very low.More convenient, easy to producing of sample.Characteristics such as and this device also has the measuring accuracy height, and the good reproducibility measuring speed is fast and simple to operation.
