  印度某公(gōng)司業(yè)務(wù)涵蓋(gài)泵(bèng)，充電樁，太陽能等，該(gāi)客(kè)戶購(gòu)買(mǎi)我司(sī)霍(huò)爾電流傳感器主要(yào)用於(yú)PLC，本(běn)來客戶(hù)需要0到20毫(háo)安輸(shū)出(chū)，但是0毫(háo)安(ān)時(shí)不能(néng)區分是(shì)真的0毫安(ān)還是(shì)無(wú)信號輸(shū)出，客戶認(rèn)為4到20毫(háo)安(ān)輸(shū)出(chū)更(gēng)加(jiā)合(hé)理，所以采用我司4到20毫(háo)安(ān)輸(shū)出(chū)的AHKC係(xì)列(liè)霍爾電(diàn)流(liú)傳感(gǎn)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.
