线性霍尔传感器在直线位移中的应用

为了实现实时的无接触直线位移测量，通过线性霍尔传感器获取磁场强度信号，采用定时中断方式完成数据采集，并以MSP430F169单片机作为运算及控制单元。考虑到普通的永磁无法形成梯度、线性的磁场分布，因此，在改进磁铁结构的基础上，提出了线性霍尔传感器非线性方法的测量方案，实现了对位置信号的无接触实时精确测量。实验结果表明，该霍尔变送器系统能实现对位置值的准确测量。

Application of Linear Hall Sensor in Linear Displacement Measurement

To implement real-time non-contact linear displacement measurement,the linear Hall sensor is used to acquire the intensity signal of magnetic field,and the timing interrupt measure is used to accomplish data acquisition;and with MSP430F169 single chip computer as operation and control unit.Considering the method using normal magnet is unable to form gradual or linear magnetic distribution,the non-linear measuring strategy with linear Hall sensor and improved structural magnet is proposed for implementing no...
