壓力變送器是一種用于測量和轉換壓力信號的設備(bei)，其工作原(yuan)理如下：

壓力(li)(li)傳(chuan)感(gan)器(qi)：壓力(li)(li)變送器(qi)內(nei)部裝有一種(zhong)或(huo)多種(zhong)類型的壓力(li)(li)傳(chuan)感(gan)器(qi)，用于(yu)測量待測介質中的壓力(li)(li)。常見(jian)的傳(chuan)感(gan)器(qi)包括(kuo)應變片式、電容式、電阻應變式等。

信(xin)號放(fang)大：傳感器獲得了(le)待(dai)測介質中的壓力信(xin)息后，會(hui)將其轉化為(wei)微弱(ruo)(ruo)電(dian)(dian)壓或微弱(ruo)(ruo)電(dian)(dian)流信(xin)號。信(xin)號調(diao)理：由于輸出微弱(ruo)(ruo)且易受(shou)干擾，需要(yao)通過(guo)放(fang)大、濾波(bo)等技術對(dui)其進行調(diao)理以提(ti)高穩定(ding)性和準確(que)性。

數字(zi)模擬(ni)(ni)轉換：將模擬(ni)(ni)數據(ju)進行(xing)數字(zi)化處理(li)，以獲得更高(gao)精度和(he)更穩定(ding)可靠性輸(shu)出。

輸(shu)出(chu)標準(zhun)信號：經過處理后(hou)，對應不同(tong)類型變(bian)送(song)器會輸(shu)出(chu)標準(zhun)4-20mA或1-5V/0-10V等標準(zhun)化直(zhi)流模擬輸(shu)數(shu)值t出(chu)。這樣就可以方便(bian)地與(yu)其他設備進行集成或連接，實現數(shu)據共享和遠程監控。福(fu)建彎道式變(bian)送(song)器
