| Abstract: | The instrument with automatic deter mination of coercivity was designed based on ARM. A 12-bit serial AD TLV2544 was used for data acquisition. An embedded web service transplanted to ARM leads to the performance of online data transferring and remote diagnosis. Besides, numerical controlled constant current source and switching power supply technology used by demagnetization were applied to this instrument. Therefore, this high precision automation device which can hold bulk sample and performs high temperature adaptability is useful for measuring the coercivity of magnetic materials fast and accurately. |
