MCGS and constant pressure water supply system of integration automation experimental facility

介绍了以变频器构成的新型恒压供水系统，详细说明了系统原理、结构以及具体器件的选择。

The apparatus use Lm336 as constant voltage source, and it been converted to constant - current source by amplification, which provide current for the Hall probe. The non-idiostatic offset circuit use the bridge method to offset the circuit. So while the magnetic density is null, the output voltage of Hall probe is null too.

仪器采用恒压源经过放大器转换为恒流源，为霍尔探头提供工作电流；不等位电势补偿电路采用桥式补偿网络，补偿电压通过调节可变电阻获得，实现霍尔电势的幅值补偿，使外磁场为零时，霍尔探头输出电势为零；磁通电路主要提供对样品的磁特性测量，它由测量线圈和积分器组成。
