GKYWG-58磁致伸縮液位計

產品概述

GKYWG-58磁致伸縮液位(wei)(wei)計(ji)是基于維拉(la)利效(xiao)應設計(ji)的遠傳式(shi)連續(xu)液位(wei)(wei)測量儀(yi)表(biao)(biao)。適用于敞(chang)開或(huo)密閉容器內的液位(wei)(wei)和(he)界(jie)位(wei)(wei)的測量。磁致伸縮液位(wei)(wei)計(ji)由(you)于其測量精度高，維護率低，現(xian)成為遠傳式(shi)連續(xu)測量液位(wei)(wei)儀(yi)表(biao)(biao)的理想選擇(ze)。

磁(ci)致(zhi)(zhi)(zhi)伸(shen)(shen)縮(suo)液位(wei)(wei)(wei)計工(gong)作時(shi)，變(bian)(bian)送器(qi)的觸發電(dian)(dian)(dian)路(lu)(lu)部(bu)分激勵出(chu)(chu)脈(mo)(mo)(mo)沖(chong)電(dian)(dian)(dian)流，電(dian)(dian)(dian)流沿(yan)磁(ci)致(zhi)(zhi)(zhi)伸(shen)(shen)縮(suo)線傳播(bo)產生脈(mo)(mo)(mo)沖(chong)電(dian)(dian)(dian)流磁(ci)場(chang)(chang)。在磁(ci)致(zhi)(zhi)(zhi)伸(shen)(shen)縮(suo)液位(wei)(wei)(wei)計的傳感器(qi)測桿外配有磁(ci)性浮(fu)(fu)子(zi)(zi)(zi)，浮(fu)(fu)子(zi)(zi)(zi)沿(yan)測桿隨液位(wei)(wei)(wei)的變(bian)(bian)化而(er)發生位(wei)(wei)(wei)移。在浮(fu)(fu)子(zi)(zi)(zi)內(nei)部(bu)裝(zhuang)有磁(ci)環，當脈(mo)(mo)(mo)沖(chong)電(dian)(dian)(dian)流磁(ci)場(chang)(chang)與(yu)浮(fu)(fu)子(zi)(zi)(zi)磁(ci)環磁(ci)場(chang)(chang)相遇時(shi)，浮(fu)(fu)子(zi)(zi)(zi)周圍的磁(ci)場(chang)(chang)發生改變(bian)(bian)從而(er)使磁(ci)致(zhi)(zhi)(zhi)伸(shen)(shen)縮(suo)線在浮(fu)(fu)子(zi)(zi)(zi)停留的位(wei)(wei)(wei)置產生一個扭(niu)轉(zhuan)波脈(mo)(mo)(mo)沖(chong)，這(zhe)個脈(mo)(mo)(mo)沖(chong)以固定的速度沿(yan)磁(ci)致(zhi)(zhi)(zhi)伸(shen)(shen)縮(suo)線傳回(hui)至變(bian)(bian)送器(qi)由檢(jian)測電(dian)(dian)(dian)路(lu)(lu)檢(jian)出(chu)(chu)，通過(guo)中央處理器(qi)計算脈(mo)(mo)(mo)沖(chong)電(dian)(dian)(dian)流與(yu)扭(niu)轉(zhuan)波脈(mo)(mo)(mo)沖(chong)的時(shi)間(jian)差可以準確地確定出(chu)(chu)浮(fu)(fu)子(zi)(zi)(zi)所在的位(wei)(wei)(wei)置，即液面(mian)的位(wei)(wei)(wei)置。變(bian)(bian)送器(qi)模(mo)電(dian)(dian)(dian)轉(zhuan)換電(dian)(dian)(dian)路(lu)(lu)輸出(chu)(chu)4-20mA或RS485 MODBUS信號，從而(er)實現液位(wei)(wei)(wei)信號遠傳的目的。
