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.項目概述 Project overview:

做鋰(lǐ)電池(chí)的(dí)公司，需要(yào)使(shǐ)用(yòng)直(zhí)流霍(huò)爾傳感(gǎn)器將直流電(diàn)流傳(chuán)輸(shū)到4-20mA模擬(nǐ)信號輸(shū)出(chū)。客戶在確認了輸(shū)入(rù)輸出(chū)和工(gōng)作電(diàn)源(yuán)後(hòu)，選擇了AHKC-EKA和(hé)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.開口(kǒu)式霍爾傳感器優(yōu)點Advantages of open type Hall sensor

與傳統直(zhí)流(liú)電(diàn)流(liú)計量(liáng)一(yī)般采用(yòng)分流器或(huò)互感器測(cè)量方法(fǎ)相比(bǐ)，開口(kǒu)式霍爾傳感(gǎn)器(qì)具有(yǒu)以下優點
：

1）原(yuán)邊副邊絕緣強度(dù)高，可達AC 12kV隔離；

2）無(wú)插入損耗(hào)；

3）動(dòng)態性能(néng)好
：響(xiǎng)應時(shí)間(jiān)小於20us跟蹤(zōng)速度(dù)di/dt高於(yú)20A/us

4) 安裝時(shí)無需(xū)拆卸原(yuán)邊電纜或(huò)母排，特(tè)別適(shì)用(yòng)於不允許斷電(diàn)設備的(dí)改造(zào)施(shī)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.

4.應(yīng)用(yòng)Application

霍爾電流傳(chuán)感器主要(yào)應用(yòng)在工廠(chǎng)改(gǎi)造直流(liú)配(pèi)電(diàn)係(xì)統中，如(rú)電廠(chǎng)直(zhí)流電源(yuán)係(xì)統改(gǎi)造，光(guāng)伏，UPS,電機係(xì)統等，它能將係(xì)統(tǒng)中(zhōng)原邊直(zhí)流電(diàn)流信號轉換(huàn)成(chéng)為(wéi)標準DC± 5V或4-20mA輸(shū)出，起到了監測和電氣(qì)隔離作用(yòng)，可(kě)與(yǔ)多(duō)回路(lù)監控(kòng)儀表(biǎo)或其他(tā)電氣測(cè)量儀表(biǎo)配套(tào)使用。

Hall current sensor is mainly used in factory transformation of DC power distribution system, photovoltaic, UPS, motor system, etc. It can convert the primary DC current signal in the system into a standard DC ± 5V or 4-20mA output, which plays a role in monitoring and electrical isolation , It can be used with multi-loop monitoring instruments or other electrical measuring instruments.
