总线供电指标F490

温度 流 压力

F490是一个回路供电指示灯，显示实际的工艺值，范围和回路电流。要显示的测量单元只需通过阿尔法数值配置菜单进行选择。没有不干胶标签必须放在外壳的外面:一个天气证明和用户友好的解决方案!量程、偏移量和小数数的配置是通过软件功能完成的，没有任何敏感的dip开关或微调器。广泛的选项进一步增强了该模型的功能，包括危险区域应用的本质安全性。输入电路与背光电路分离。该F490接受4 - 20mA输入信号从广泛的过程仪器，包括流量(线性或平方根)，液位，压力和温度变送器。所有这些工艺参数都可以在各自的工程单元中显示。优点-坚固的铝或不锈钢316L现场外壳(IP66, IP67 / NEMA Type4X)。-它很坚固，卡车甚至可以站在上面! - Intrinsically Safe available - ATEX, IECEx and CSA approval for gas and dust applications. - Familiar easy operation with the Fluidwell "Know one, know them all" configuration structure, saving time, cost and aggravation. - Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors. Applications - Applications where a local, loop powered, general purpose display is required without monitoring function, linearization or signal re-transmitting. - The F490 takes operating energy from an input current (2-wire 4 - 20mA) and has a separated backlight circuit.
