FUEHLERSYSTEME传感器DMU/A

FUEHLERSYSTEME DMU/A用于压差和体积流量的压力传感器，有源输出（0-10 V 或 4-20 mA）

-5000 ... + 5000 Pa，0-200,000 立方米/小时

每个版本 8 个测量范围

0-10 V，4-20 mA，继电器

输出衰减 0 秒 / 1 秒 / 5 秒 / 10 秒 通过 DIP 开关可选择

铰链锁技术

压力变送器检测两个压力输入之间的过压、欠压或压差 (P)，并将测量值转换为 0-10 V 或 4-20 mA 的线性输出信号。可以在设备上设置 8 种不同的比例和压力变送器的输出阻尼（0 秒/1 秒/5 秒/10 秒）。

或者，测量装置可以作为体积流量测量装置运行。它使用系统特定的 K 系数 (k) 计算体积流量 (Q) 并将计算值输出为线性输出信号 0-10 V 或 4-20 mA。 K 系数、体积流量输出信号 0-10 V 或 4-20 mA 的所需标度、介质密度和所需体积单位（l 或 m³ per s / min / h）可以通过以下方式方便地设置显示菜单。

背光显示的内容可以通过菜单和实际值、设置的切换阈值、继电器状态、所选间隔（1 h / 6 h / 12 h / 24 h) 等可以读取。为了现场手动校准零点，压力变送器只需按一下按钮即可进行零点调整。如有必要，可以使用 SPAN 控制器在现场对压力变送器进行精细校准。

Manual zero-point adjustmentThe zero point adjustment is started by pressing the button on the circuit board (push 10 s until LED stops flashing or by the display version the countdown 10-0 is completed). Before, a continuous operation of at least 1 hour must be sure, the offset must be in the middle position and the pressure inputs P+ and P- must be an obvious offense to the environment. The successful calibration will be signalized by 5 sec durable lightning of the LED.
