1.项目概述： Project Overview

印度某公司业务涵盖泵、充电桩、太阳能等，该客户购买我司霍尔电流传感器主要用于PLC，本来客户需要0到20毫安输出，但是0毫安时不能区分是真的0毫安还是无信号输出，后来,客户认为4到20毫安输出更加合理，所以采用我司4到20毫安输出的AHKC系列霍尔电流传感器。

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.
