DC/AC Magnetic Measuring Equipment for Soft Magnetic Materials - 1

LABORATORIO ELETTROFISICO AMH-SERIES - SOFT MAGNETIC MATERIALS PERMEAMETERS Characterize rings and strips at high resolution in DC and AC The AMH-series Permeameters are automatic measuring systems to characterize rings and strips in DC and AC conditions. Laboratorio Elettrofisico manufactures a complete line of combination permeameters for soft magnetic materials for DC up to 1 MHz. DC measurement provides analysis for the intrinsic and static properties. The AC measurement offers analysis for the behavior of the materials under dynamic conditions. Dynamic properties are affected by many factors depending on the particular application conditions. Laboratorio Elettrofisico AC permeameter provides the designer with realistic characteristics of power losses, saturation field and induction performance relating to thickness of the material and the electrical resistivity. • Remanence Br, coercivity Hc, saturation values Hsat, Bsat, Jsat, cycle area, relative permeability, losses, losses separation, etc. • All DC/AC AMH-series meet the International Standards IEC 60404-4, IEC 60404-2, IEC 60404-6 and ASTM A773 • Automatic measurement of complete DC or AC hysteresis loop, normal magnetization curve, permeability curve • The measuring cycle is fully automatic and is controlled by Laboratorio Elettrofisico exclusive software (Neon 1.0), resulting in complete characterization of the material under test STANDARD CONFIGURATION The main cabinet containing: • Fluxmeter • Arbitrary Function Generator • Power amplifier • Fast Acquisition Unit • Reference sample for day-to-day control • Dedicated software Neon 1.0 • PC and printer • Connection tool for ring sample

MODEL DIMENSIONS HOW IT WORKS The sample has to be prepared winding a primary set of turns NH (Drive) around the sample for excitation and a secondary set of turns NB (Sense) to detect the magnetic flux. The H(t) field is determined measuring the current i(t) in the primary winding: H(t)= NH• i(t)/ℓ, where ℓ is the magnetic path. The current is measured by measuring the voltage across a low-inductance resistance R (shunt). For DC measurements, B is measured through the flux Ф by use of a fluxmeter, while for AC measurements, the B(t) field is determined by integrating the voltage V(t) from the...

Module for improved sensitivity In order to increase the resolution at low field (few A/m) is available a module for improved sensitivity. RC-50-60-5-LF/HF Ring-coil Ring coils (RC) are used to measure ring specimens without the necessity to wind turns on them. A ring coil consists basically of an open multipolar connector, in which its pins are connected to give Nh excitation turns and NB measuring turns when closed. Ring coils are usually tailored on specific sizes, materials, frequencies, levels, since different measuring conditions require different NH and NB values. Most of the ring...
