FUEHLERSYSTEME传感器DMU2/A
FUEHLERSYSTEME传感器DMU2/A带 EMC 螺纹的压力差压力传感器
压力传感器 DMU2 / A 记录两个压力出口处的过压、欠压和压差，并将测量值转换为 0-10 V 和 4-20 mA 的线性输出信号。 可选择8种不同的刻度，使用创新的拨码开关技术可以自由切换。 压力传感器的输出衰减（0 秒/1 秒/5 秒/10 秒）也可以使用 DIP 开关进行选择。 对于零点的手动校准，压力传感器只需按一下按钮即可在原位执行零点平衡。 如果需要，可以使用 SPAN 控制器对压力传感器进行原位精细校准。 铝制外壳确保了的机械坚固性，并带有 EMS 螺纹，可轻松安全地进行符合 EMC 的接线。

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.
