Dwyer A3000系列Photohelic®差压开关/差压表
Dwyer A3000系列Photohelic®差压开关/差压表
A 3000系列压差开关/压差表具有多功能、高度可重复的压力开关功能，并采用经过时间验证的Magnehelic压力表设计。压差开关/表测量和控制空气和兼容气体的正、负压或差压。标准型号耐压为25 psig(1.7 bar)，可选项为35(2.4)或80(5.5 bar)psig。两个光电晶体管驱动，DPDT继电器包括低/高位控制。易于调整的设定点指示器是由位于表面上的旋钮控制的。单个设置点死区是一个指针宽度-小于全尺度的1%。设置点可以相互锁定，以提供可变的死区-理想的控制风扇，阻尼器等。表读数是连续的，即使是在失去电能的时候不受开关操作的影响。规格压力范围选择从一个低0-0.25"w.c.(0-6毫米)至30 psi(21BAR)。
