开启式高精度霍尔传感器设计

Design of Open and High Precision Hall Sensor

针对通用型开启式霍尔传感器产品精度低(一般为1.0级)的问题,提出了可提升开启式霍尔传感器精度的系列设计方法。该系列方法涉及产品磁芯设计、霍尔器件选型、结构设计及抗干扰等方面,将其应用于实际产品开发中,产品精度可提升为0.5级。该系列设计方法可为相关产品开发人员提供技术参考。

Aiming at the low precision of the general open Hall sensor （generally, it about 1.0）, put forward series of methods to increase the Hall sensor precision. These methods involved the magnetic core designing, Hall device electing, product structure designing, anti-interference, and so on, applied them into developing product, the actual product precision could improve with a magnitude of 0.5. These design methods can provide technical reference for relevant product development staff.
