差壓傳感器(qi)(qi)采用德國先進的 MEMS 技術制成的單晶 硅傳感器(qi)(qi)芯片(pian)、全球的單晶硅雙(shuang)梁(liang)懸浮式設計。福(fu)建彎道式變送(song)器(qi)(qi)

壓(ya)(ya)力變送(song)器是一種(zhong)用(yong)于測量和轉換壓(ya)(ya)力信(xin)號的設備(bei)，其工作(zuo)原(yuan)理如下：

壓力(li)傳感(gan)器(qi)：壓力(li)變(bian)送器(qi)內部裝有一種或多種類型的(de)壓力(li)傳感(gan)器(qi)，用(yong)于測量(liang)待測介質中的(de)壓力(li)。常見的(de)傳感(gan)器(qi)包括應(ying)變(bian)片(pian)式(shi)、電容式(shi)、電阻應(ying)變(bian)式(shi)等。

信(xin)號放大(da)：傳感器獲得(de)了待測介質(zhi)中的壓力(li)信(xin)息后，會將其轉化為微(wei)弱電壓或微(wei)弱電流信(xin)號。信(xin)號調(diao)理(li)：由于(yu)輸(shu)出微(wei)弱且易受(shou)干(gan)擾，需要通過放大(da)、濾波等(deng)技術對其進行(xing)調(diao)理(li)以提高穩定性和準確性。

數(shu)(shu)字模擬轉換：將模擬數(shu)(shu)據進行數(shu)(shu)字化處理，以獲得更(geng)高精度和更(geng)穩定(ding)可靠性輸出。

輸(shu)出(chu)標準信號(hao)：經(jing)過處理后，對(dui)應不同類型變送(song)器(qi)會輸(shu)出(chu)標準4-20mA或1-5V/0-10V等標準化直流模擬(ni)輸(shu)數值t出(chu)。這樣就可以方便地與其他(ta)設備(bei)進行集成(cheng)或連接，實現數據(ju)共享和(he)遠程監控。福建彎道(dao)式變送(song)器(qi)
