616KD-B-50/51/52/53/54/55/56/57/58 Dwyer德威爾 差壓變送器

帶***鍵校準(zhǔn)技術(shù)的616KD差壓變送器結(jié)構(gòu)簡(jiǎn)單，便于安裝和專(zhuān)業(yè)維護(hù)。

這個(gè)***鍵校準(zhǔn)的差壓變送器是性價(jià)比高，小巧,價(jià)格低的變送器。它不僅消除了象其

它變送器***樣的繁瑣的調(diào)整，而且無(wú)需校準(zhǔn)量程。只需按***按鍵就能將零點(diǎn)和量程

校準(zhǔn)。無(wú)需使用參考?jí)毫υ春推渌?zhǔn)設(shè)備，無(wú)需卸下再送到校驗(yàn)室去校準(zhǔn)。所有

需要做的事情就是在差壓平衡為零的時(shí)候按下按鍵，比起傳統(tǒng)的變送器要每年拆卸

變送器送去校準(zhǔn)量程來(lái)說(shuō)，它能在產(chǎn)品服務(wù)期內(nèi)節(jié)約大量時(shí)間。和外殼***起模壓的

安裝孔使得安裝非常簡(jiǎn)單。

616KD還能夠安裝在35mmDIN導(dǎo)軌上，帶側(cè)面和背部的導(dǎo)軌卡。在外殼的上部，它

帶有容易接線的接線排。可選擇帶有接線排保護(hù)蓋。

***鍵校準(zhǔn)技術(shù)***族的差壓變送器***理想用于樓宇自動(dòng)化應(yīng)用場(chǎng)合：空氣處理機(jī)，風(fēng)

管，變風(fēng)量和過(guò)濾監(jiān)測(cè)。根據(jù)選擇的型號(hào)不同，可以選擇的量程從1英寸水柱到20英

寸水柱。
