1.項目概述： Project Overview

印度某公司業(yè)務涵蓋泵、充電樁、太陽能等，該客戶購買我司霍爾電流傳感器主要用于PLC，本來客戶需要0到20毫安輸出，但是0毫安時不能區(qū)分是真的0毫安還是無信號輸出，客戶認為4到20毫安輸出更加合理，所以采用我司4到20毫安輸出的AHKC系列霍爾電流傳感器。

The Indian company's business covers pumps, charging piles, solar energy, etc. The Hall current sensor they purchased is mainly installed PLC.Originally, customers need 0-20 mA output, but at 0 mA, it is not possible to distinguish whether it is true 0 mA or no signal output.In the end, the customer thought that 4-20 mA output is more reasonable, so we use our AHKC series Hall current sensor with 4-20 mA output.
