Dwyer 电子压力控制器 EDA系列

2 Switches, Indicating Gage, and Transmitter in One Package

EDA系列电子压力控制是一种非常通用的紧凑封装,可以在一个系统中取代一个单独的压力表,两个开关,和一个变送器,节省资金,安装时间,和面板空间。EDA集成了两个SPDT继电器,在控制或报警使用的范围内,开关点完全可调。正面有LED指示灯的开关状态和一个大背光两线显示过程值和指示单位。简单的菜单结构,两行显示和外部编程按钮,编程容易。耐风雨外壳是各种应用的理想选择,具有面板安装,冲洗安装,或管道安装能力。功能包括零点设置,可调衰减,菜单锁定,峰值和山谷指示,可移动终端块,可调时间延迟,可缩放发射机输出。

应用及案例


•  Process control

•  Compressor control

•  Filter status

产品特色


•  Display Units: psi, kg/cm², bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in² (choices depend on range).

•  Test Mode: Simulates input over the range without pressuring to easily test switches and transmitter output feature.

•  Fail-safe: For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.

•  Alternation: Selectable alternation of set points between the relays for even wear on duplex pump applications.

•  Versatile Compact Package: Can replace a separate gage, two switches, and a transmitter in a system saving, money, installation time, and panel space.

•  Fully Programmable: To meet simple or complex application needs.

•  Weatherproof Housing: Ideal for a wide variety of applications with panel mount, flush mount, or pipe mount ability.
