AC Hysteresisgraph - Model MATS-2010SA Instrument

Detailed Product Description

Under continuous frequency of 1 kHz to 500 kHz, automatic measurement of magnetic hysteresis loop of the soft magnetic materials such as silicon steel, precision alloy, non-crystal  and ferrite, accurate measurement on the dynamic magnetic characteristic parameters such as amplitude permeability μa, loss angle δ, loss iron Pc, remanence Br and coercivity Hc. Windows measurement software applied simply. 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, power meter, the whole testing process is automatic completed.

 

 

General Features

 

·Testing sample varieties: soft magnetic ferrite, permalloy, amorphous and nano crystal. 

·Test sample shapes: annular, E and U shapes. 

·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. 

·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%. 

·Magnetic induction obtained through digital integration of coil measuring voltage, magnetic induction peak value locked through digital feedback, magnetic induction lock precision 0.5%.

·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. 

·Different power sources can be selected according to different test requirements: 1 kHz ~ 300 kHz or 500 kHz, 5 kHz or 10 kHz ~ 100 kHz or other frequency ranges customized. 

·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'', μ_L, μ_R, Q and A_L, etc. 

·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. 

·Powerful function of the software, the technical request to the testing staff is very low.
