無運動部件，頻率和4至20毫安輸出，免維護
MFS磁感應(yīng)流量傳感器是一種緊湊、低成本的槳輪傳感器的替代品。與帶有運動部件的傳感器不同，MFS可用于處理污染介質(zhì)的應(yīng)用。該系列提供可靠的測量技術(shù)、無障礙管道橫截面以及快速響應(yīng)時間，使該系列成為無干擾操作的理想選擇。液體的溫度、密度、粘度、濃度或電導(dǎo)率的任何變化都不會影響磁感應(yīng)式流量傳感器的輸出信號。除了使用壽命長外，這一系列產(chǎn)品非常適合于精確可逆測量封閉管道中導(dǎo)電液體的體積流量。
工作原理
測量管處于磁場中。如果具有一定流量的導(dǎo)電介質(zhì)通過管道，它將以與磁場成直角的方向通過，從而產(chǎn)生一個與平均流速成比例的電壓，并由MFS內(nèi)的兩個電極拾取。可獲得與流量成比例的頻率輸出信號（可提供模擬輸出選項）。
產(chǎn)品應(yīng)用
