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15 psig 外殼 : 不銹鋼和PC ABS合金，
準確率±0.8% 認證： UL 94 v- 0 阻燃性等級。
我們低成本系列668 b / D緊湊型壓差變送器測量差壓精度為±0.8% FS,并將這個壓差轉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、輕量級的設計使安裝簡單和容易。
此單元是防止不正確的連接,包括一個接線端保護蓋。
特點/好處：
1， 保護來自15 psi超壓和不正確的連接,
2， 高精度低壓力范圍
3， 兩個壓力連接方案選擇，以便于安裝在的場合。
應用：
1， 暖通空調及變風量空調控制
2， 潔凈室和隔離的房間
3， 管道靜壓測量
