currentACmagnetic field

The DX-2012SA soft magnetic AC measuring device automatically measures the AC hysteresis loop, magnetization curve and loss curve of soft magnetic materials such as soft ferrite, permalloy, amorphous and nanocrystalline under dynamic (AC) conditions. Accurately measure remanence Br, coercive force Hc, specific total loss Ps, amplitude permeability µa, loss angle δ, resistive permeability µR, inductive permeability µL, elastic permeability µ′, viscous permeability µ ", inductance coefficient AL and Q value and other dynamic magnetic characteristic parameters. It conforms to China National Standards GB 5026-85, GB 3658-90, GB/T 9632.1-2002, GB/T 19346-2003, industry-standard SJ/T 10281-91 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, and power meter, the whole testing process is automatically completed. General Features of AC Hysteresis Graph (DX-2012SA) 1. Testing sample varieties: soft magnetic ferrite, permalloy, amorphous, amorphous and nm crystal. 2. Test sample shapes: annular, E and U shapes. 3. Test samples with a closed magnetic circuit can be directly winded and measured on samples. Sample, magnetizing coil (N1) and measuring coil (N2) form a no-load transformer. 4. Non-inductive resistance is connected to magnetizing coil loop to determine magnetizing current and magnetic field intensity through the measurement of pressure drop on noninductive resistance, magnetic field peak value can be locked through digital feedback, and magnetic field lock precision 0.5%.
