概 述
LFM52系列微差壓變送器是我司新推出的一款差壓變送器，既有多量程傳感器的靈活性，又有單量程傳感器的高性能，是工業(yè)應(yīng)用的理想產(chǎn)品。該差壓變送器內(nèi)置多種可選的壓力范圍和單位選擇，通過內(nèi)置的撥碼開關(guān)可以方便的進(jìn)行現(xiàn)場調(diào)整，采用IP65防護(hù)等級的外殼，并配備便于布線的不銹鋼導(dǎo)管接頭，適用于暖通空調(diào)（HVAC）、能源管理系統(tǒng)、VAV及風(fēng)扇控制、環(huán)境污染控制、靜態(tài)管路和潔凈室壓力、煙霧罩控制、烘箱增壓及爐通風(fēng)控制等領(lǐng)域。
