? 現(xiàn)場升級為LCD數(shù)顯無需倉儲兩臺不同的變送器，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。無需太多的倉儲量，你總有能滿足量程要求的變送器。
? 數(shù)字按鍵校準零點和量程取代傳統(tǒng)的電位器校準的方式，大大節(jié)約了校準時間，降低了維護成本。
? 可調(diào)數(shù)字阻尼用于平滑頻繁波動的壓力，常用于氣流監(jiān)控應用場合。
? 可現(xiàn)場改為風速型用于風機等應用場合?？刹捎闷椒礁敵鲋苯语@示fpm或m/s風速。無需用智能可編程顯示儀或PLC來換算差壓成風速。不僅節(jié)約硬件成本，而且減少安裝時間。
