FUEHLERSYSTEME傳感器DMU2/A帶 EMC 螺紋的壓力差壓力傳感器

壓力傳感器 DMU2 / A 記錄兩個壓力出口處的過壓、欠壓和壓差，并將測量值轉(zhuǎn)換為 0-10 V 和 4-20 mA 的線性輸出信號。 可選擇8種不同的刻度，使用創(chuàng)新的撥碼開關(guān)技術(shù)可以自由切換。 壓力傳感器的輸出衰減（0 秒/1 秒/5 秒/10 秒）也可以使用 DIP 開關(guān)進(jìn)行選擇。 對于零點(diǎn)的手動校準(zhǔn)，壓力傳感器只需按一下按鈕即可在原位執(zhí)行零點(diǎn)平衡。 如果需要，可以使用 SPAN 控制器對壓力傳感器進(jìn)行原位精細(xì)校準(zhǔn)。 鋁制外殼確保了極高的機(jī)械堅(jiān)固性，并帶有 EMS 螺紋，可輕松安全地進(jìn)行符合 EMC 的接線。

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.
