為了智能電磁流量計(jì)能夠很好地正常使用，智能電磁流量計(jì)傳感器接地一定要安裝好。智能電磁流量計(jì)傳感器接地時(shí)，應(yīng)注意以下幾點(diǎn)： </p> <p> 1、傳感器、轉(zhuǎn)換器的接地在現(xiàn)場(chǎng)，去二次儀表的屏蔽層在控制室一側(cè)接地，切勿多端接地，以免因電位不同而引入干擾。 </p> <p> 2、傳感器安裝在金屬管道上，可將傳感器的接地導(dǎo)線按制造廠的要求連接在管道法蘭上，形成可靠的接地回路儀表的接地點(diǎn)應(yīng)是一個(gè)**的接地點(diǎn)，不可以共用其他電氣設(shè)備的接地。 </p> <p> 3、傳感器的測(cè)量管、外殼、屏蔽線、轉(zhuǎn)換器及二次儀表都要接地。 </p> <p> 4、傳感器、轉(zhuǎn)換器應(yīng)單獨(dú)接地，不要連在電動(dòng)機(jī)、工藝管道上，接地電阻應(yīng)小于10歐姆。定式超聲波流量計(jì)，通常都有4-20mA信號(hào)輸出等功用，供遠(yuǎn)傳顯現(xiàn)運(yùn)用，但其內(nèi)部只能存貯一條管道的參數(shù)；</p><div style="width:100%;text-align:
