Dwyer 668B/D紧凑型差压变送器
范围从0.1到100 in w.c., 超压保护15 psig 外壳 : 不锈钢和PC ABS合金，
准确率±0.8% 认证： UL 94 v- 0 阻燃性等级。
我们低成本系列668 b / D紧凑型压差变送器测量差压精度为±0.8% FS,并将这个压差转换成比例高水平模拟输出单向和双向压力范围。
这些变送器可以承受15 psig超压,不被损坏。紧凑的、轻量级的设计使安装简单和容易。
此单元是防止不正确的连接,包括一个接线端保护盖。
特点/好处：
1， 保护来自15 psi超压和不正确的连接,
2， 高精度低压力范围
3， 两个压力连接方案选择，以便于安装在的场合。
应用：
1， 暖通空调及变风量空调控制
2， 洁净室和隔离的房间
3， 管道静压测量
