摘要
在采用电涡流原理测量熔铝电阻率的研究中变通使用 L VDT专用芯片 AD5 98,合理设计传感器结构和标定方法 ,从而简化了硬件电路 ,消除了温度影响 。
AD598-LVDT special interface chip is adapted to measur e molten aluminum electrical resistivity based on the eddy current principles in the device. Structure and calibrating method of the transducer in the device ar e properly designed in order to simplify the hardware circuit and eliminate temp erature effect. The device is applied to the freezing study of molten aluminum a nd aluminum alloy.
