With the development and application of new materials, higher requirements are put forward for magnetic measurement of materials. In fact, in addition to electromagnets, DC motors and DC relays are also used in static magnetization conditions, so the DC magnetic characteristics are particularly important.
Magnetism and magnetic materials have become an important symbol to measure the degree of informatization of a country. According to statistics, China's output of magnetic materials ranks first in the world, and it has a high technical level in the field of development and production of magnetic materials. With the development and application of new materials, higher requirements are put forward for magnetic measurement of materials. In fact, in addition to electromagnets, DC motors and DC relays are also used in static magnetization conditions, so the DC magnetic characteristics are particularly important.
In
measurement of soft magnetic materialsDC magnetic measurement, the impact method is better than the measurement device is simple, high sensitivity, high measurement accuracy, is still one of the standards of DC magnetic measurement in China, is still very common in practical applications. Magnetic induction intensity is one of the basic parameters reflecting the static state of magnetic materials. It is a parameter that many kinds of sensors are manufactured and must be inspected by application manufacturers when materials enter the factory for inspection. It is also one of the items that must be inspected by magnetic material manufacturers in the development of new processes and regular production. When the impact method is used to measure the magnetic induction intensity, since the impact method is the measurement of the sample by the impact galvanometer, the impact constant has an important influence on the measurement accuracy of the magnetic induction intensity. Therefore, accurate calibration must be carried out before measuring the magnetic induction intensity. Based on accurate measurement of shock constants.

measurement of soft magnetic materialsThe magnetic induction intensity can be obtained from the measurement principle of the DC impact method.
DC Measurement System for FE-2100SD Soft Magnetic Materials, automatically measure the basic magnetization curve and hysteresis loop of soft magnetic materials under static (DC) conditions, and accurately measure the static magnetic characteristics parameters such as initial magnetic conductivity μ I, maximum magnetic conductivity μ m, saturated magnetic induction strength Bs, remanence Br, coercive force Hc and hysteresis loss Pu.
DC Measurement System for FE-2100SD Soft Magnetic MaterialsAccording to the measurement principle of the impact method, the computer control technology and A/D, D/A combination, electronic integrator to replace the traditional impact galvanometer, to achieve the simulation of impact measurement under the control of microcomputer, completely eliminate the classical impact method due to the use of impact galvanometer caused by the non-instantaneous error, improve the measurement accuracy, for the study of the material magnetization process mechanism to provide a reliable basis.
FE-2100SA type soft magnetic AC measuring deviceIt can be used for accurate measurement of closed-circuit samples of soft magnetic materials such as soft magnetic ferrite, permalloy, amorphous and nanocrystalline.
The product complies with GB/T3658-2008, GB/T19346-2003 and SJ20966-2006, IEC 60404-6. Automatically measure the AC hysteresis loop, magnetization curve and loss curve of soft magnetic materials under dynamic (AC) conditions. Accurately measure dynamic magnetic characteristic parameters such as remanence Br, coercivity Hc, specific total loss Ps, amplitude permeability µa, loss angle δ, resistance permeability µR, inductance permeability µL, elastic permeability µ', viscous permeability µ", inductance coefficient AL and Q value. In order to fully grasp the material AC characteristics to provide powerful basic data, the measurement process is automatically completed; power protection, over-current and over-voltage automatic interruption, high reliability.
Using advanced AMR single-chip processing technology, 255 test points are automatically and continuously measured. The test time of each test point is about 12 seconds. Different modes such as fixed frequency, fixed Bm or fixed Hm can be selected for multi-point test to measure AC magnetization curve and loss curve.
