摘要
应用基于霍尔效应的磁平衡原理设计了直流电压高精度隔离传送传感器,并与光耦传感器进行了比较,结果表明:在温度变化的环境中,该传感器隔离传送直流电压的精度优于光耦传感器28倍.
Using the magnetic-balance principle of Hall effect, a sensor having low temperature float is designed to isolated transmission of DC voltage at high accurate. The comparison with optical isolated sensor reveales that the accuracy of the new design is 28 times higher even when worked in temperature-varying environment.
