System Structure

Mode JDAW-2015 multi-parameter measurement system of magnetostrictive materials is the device, which the material magnetic parameters (such as ldc –Hdc, Bdc-Hdc, lac-Hac, Bac-Hac, Zac-f, Hcb, Hcj, Br and BHmax etc. ) changes with the applied AC and DC magnetic field can be measured. The system is composed of an electromagnet, an electromagnet power supply, a fluxmeter, a gaussmeter, a strain gauge, a Helmholtz coil, an impedance tester, an audio frequency power supply, a data acquisition system, a pressure bag, a computer and a laser printer.
