摘要
AD598是 LVDT 和 RVDT 专用的信号调节系统,文中使用该芯片实现对线性差动电感式(LVDI)传感器信号的处理与转换,完成对植物叶片厚度变化微位移的测量。该信号调理电路具有零位调整、增益选择的功能,与传统的电路相比,电路简单、体积小。
Although AD598 is LVDT and RVDT special-purpose signal control system, this CMOS chip is used to process and transform LVDI （linear differential motion inductance type） sensor＇s signal in the article to realize the micro displacement＇s survey to the change of plant blade thickness. The circuit is simpler and smaller size than the conventional one, also has the zero setting and function gain select.
