Dwyer 668B/D緊湊型差壓變送器

范圍從0.1到100 in w.c., 超壓保護(hù)15 psig 外殼 : 不銹鋼和PC ABS合金，
準(zhǔn)確率±0.8% 認(rèn)證： UL 94 v- 0 阻燃性等級(jí)。

我們低成本系列668 b / D緊湊型壓差變送器測(cè)量差壓精度為±0.8% FS,并將這個(gè)壓差轉(zhuǎn)換成比例高水平模擬輸出單向和雙向壓力范圍。
這些變送器可以承受15 psig超壓,不被損壞。緊湊的、輕量級(jí)的設(shè)計(jì)使安裝簡(jiǎn)單和容易。
此單元是防止不正確的連接,包括一個(gè)接線端保護(hù)蓋。

特點(diǎn)/好處：
1，保護(hù)來(lái)自15 psi超壓和不正確的連接,
2，高精度低壓力范圍
3，兩個(gè)壓力連接方案選擇，以便于安裝在的場(chǎng)合。

應(yīng)用：
1，暖通空調(diào)及變風(fēng)量空調(diào)控制
2，潔凈室和隔離的房間
3，管道靜壓測(cè)量
