FUEHLERSYSTEME DMU/A用于壓差和體積流量的壓力傳感器，有源輸出（0-10 V 或 4-20 mA）

-5000 ... + 5000 Pa，0-200,000 立方米/小時

每個版本 8 個測量范圍

0-10 V，4-20 mA，繼電器

輸出衰減 0 秒 / 1 秒 / 5 秒 / 10 秒 通過 DIP 開關(guān)可選擇

鉸鏈鎖技術(shù)

壓力變送器檢測兩個壓力輸入之間的過壓、欠壓或壓差 (P)，并將測量值轉(zhuǎn)換為 0-10 V 或 4-20 mA 的線性輸出信號。可以在設(shè)備上設(shè)置 8 種不同的比例和壓力變送器的輸出阻尼（0 秒/1 秒/5 秒/10 秒）。

或者，測量裝置可以作為體積流量測量裝置運行。它使用系統(tǒng)特定的 K 系數(shù) (k) 計算體積流量 (Q) 并將計算值輸出為線性輸出信號 0-10 V 或 4-20 mA。 K 系數(shù)、體積流量輸出信號 0-10 V 或 4-20 mA 的所需標(biāo)度、介質(zhì)密度和所需體積單位（l 或 m3 per s / min / h）可以通過以下方式方便地設(shè)置顯示菜單。

背光顯示的內(nèi)容可以通過菜單和實際值、設(shè)置的切換閾值、繼電器狀態(tài)、所選間隔（1 h / 6 h / 12 h / 24 h) 等可以讀取。為了現(xiàn)場手動校準(zhǔn)零點，壓力變送器只需按一下按鈕即可進(jìn)行零點調(diào)整。如有必要，可以使用 SPAN 控制器在現(xiàn)場對壓力變送器進(jìn)行精細(xì)校準(zhǔn)。

Manual zero-point adjustment The 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.
