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'', μL, μR, Q and AL, etc. 

·Automatic and continuous measurement up to 255 testing points. 

·Powerful function of the software.
