Abstract:This article introduces the application of the Hall Sensor used in chile. Hall current sensors are mainly used to isolate and convert AC, DC, pulse and other complex signals. After signal control of current signals are converted according to the Hall Effect Theory, they can be directly acquired by AD, DSP, PLC, secondary instruments and other devices. Hall current sensors are widely applicable for acquisition and feedback in the current monitoring, battery application, inverter, solar power management, direct current cabinet, DC motor drive, electroplating, welding, frequency converter, UPS servo control systems. They feature the quick response, wide range of measurement, high precision, strong overload capacity, good linearity and excellent anti-interference performance.

1.项目概述 Project overview:

做锂电池的公司，需要使用直流霍尔传感器将直流电流传输到4-20mA模拟信号输出。客户在确认了输入输出和工作电源后，选择了AHKC-EKA和AHKC-EKAA。 

The company that do lithium batteries need to use DC Hall sensors to transmit DC current to the 4-20mA analog signal output. After confirming the input and output and working power, the customer chose AHKC-EKA and AHKC-EKAA.

2.开口式霍尔传感器优点Advantages of open type Hall sensor

与传统直流电流计量一般采用分流器或互感器测量方法相比，开口式霍尔传感器具有以下优点：

1）原边副边绝缘强度高，可达AC 12kV隔离；

2）无插入损耗；

3）动态性能好：响应时间小于20us跟踪速度di/dt高于20A/us

4) 安装时无需拆卸原边电缆或母排，特别适用于不允许断电设备的改造施工。

Compared with the traditional DC current measurement method generally adopted by shunt or transformer, the open-type Hall sensor has the following advantages:

1) High insulation strength of primary side and secondary side, up to AC 12KV isolation;

2) No insertion loss;

3) Good dynamic performance: the response time is less than 20uS and the tracking speed Di /dt is higher than 20A/ uS

4) There is no need to disassemble the original side cable or bus during installation. It is especially suitable for the transformation and construction of equipment that is not allowed to lose power.
