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.項(xiàng)目概述 Project overview:

做鋰電池的公司，需要使用直流霍爾傳感器將直流電流傳輸?shù)?/span>4-20mA模擬信號(hào)輸出?？蛻粼?/span>確認(rèn)了輸入輸出和工作電源后，選擇了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.開(kāi)口式霍爾傳感器優(yōu)點(diǎn)Advantages of open type Hall sensor

與傳統(tǒng)直流電流計(jì)量一般采用分流器或互感器測(cè)量方法相比，開(kāi)口式霍爾傳感器具有以下優(yōu)點(diǎn)：

1）原邊副邊絕緣強(qiáng)度高，可達(dá)AC 12kV隔離；

2）無(wú)插入損耗；

3）動(dòng)態(tài)性能好：響應(yīng)時(shí)間小于20us跟蹤速度di/dt高于20A/us

4) 安裝時(shí)無(wú)需拆卸原邊電纜或母排，特別適用于不允許斷電設(shè)備的改造施工。

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.
