Dwyer EDA电子压力控制器

压力表，开关变送器一体化

介质: 可兼容的液体或气体.

接液材质: 316L SS.

外壳: Glass filled plastic.

精度: ±1% of F.S. including linearity, hysteresis, and repeatability (indicator and transmitter).

稳定性: < ±2% of F.S. per year.

压力限制: Ranges up to 6,000 psi: 1.5 x range; 8,000 psi range: 10,000 psi.

温度限制: Ambient: 20 to 140°F (-6.6 to 60°C); Process: 0 to 176°F (-18 to 80°C).

补偿温度限制: 32 to 122°F (0 to 50°C).

热效应: ±0.05% of F.S./°F.

开关特性:

开关类型: 2 SPDT relays.

电气额定: 5 A @ 120/240VAC, 1 A @ 30 VDC.

重复性: ±1% of FS (switching only).

设定点: Adjustable 0-99% of FS.

开关指示: External LED for each relay on the front panel.

开关复位: Manual or Automatic.

变送器特性:

输出: 4-20 mA, 1-6 VDC, 1-5 VDC, 0-5 VDC, or 0-10 VDC (direct or reverse output selection).

最小激励电压: 14 VDC.

零满调整: Menu scalable within the range

显示单位: 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).

测试方式: Simulates input over the range without pressuring to easily test switches and transmitter output feature.

故障保护: 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.

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