MS系列微差壓變送器
測量風(fēng)壓或風(fēng)速
MS系列 Magnesense®微差壓變送器用途廣泛，可用于監(jiān)測微壓/微差壓/真空，和監(jiān)測風(fēng)速/風(fēng)量。它的功能包括：可現(xiàn)場選擇公制/英制工程單位，可現(xiàn)場加裝LCD數(shù)顯，可調(diào)整輸出信號(hào)的阻尼系數(shù)，當(dāng)和皮托管或其它差壓風(fēng)速傳感器配合測量風(fēng)速風(fēng)量時(shí)，可選擇開方輸出。
磁感應(yīng)技術(shù)使得Magnesense®微差壓變送器性能優(yōu)異，穩(wěn)定可靠。可用于所有的微差壓，風(fēng)速風(fēng)量測量的應(yīng)用場合。

? 現(xiàn)場升級(jí)為LCD數(shù)顯無需倉儲(chǔ)兩臺(tái)不同的變送器，只需移除前蓋，將LCD組件插入，就現(xiàn)場組裝了一臺(tái)帶數(shù)顯的變送器，可輕松滿足用戶的需求。
? 現(xiàn)場可選量程不管是英制或公制。無需太多的倉儲(chǔ)量，你總有能滿足量程要求的變送器。
? 數(shù)字按鍵校準(zhǔn)零點(diǎn)和量程取代傳統(tǒng)的電位器校準(zhǔn)的方式，大大節(jié)約了校準(zhǔn)時(shí)間，降低了維護(hù)成本。
? 可調(diào)數(shù)字阻尼用于平滑頻繁波動(dòng)的壓力，常用于氣流監(jiān)控應(yīng)用場合。
? 可現(xiàn)場改為風(fēng)速型用于風(fēng)機(jī)等應(yīng)用場合。可采用平方根輸出直接顯示fpm或m/s風(fēng)速。無需用智能可編程顯示儀或PLC來換算差壓成風(fēng)速。不僅節(jié)約硬件成本，而且減少安裝時(shí)間。
