德國寶德BURKERT壓力變送器工作原理：
壓(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送器(qi)(qi)感受壓(ya)(ya)(ya)力(li)的電(dian)(dian)器(qi)(qi)元件一(yi)(yi)般(ban)為(wei)(wei)電(dian)(dian)阻(zu)(zu)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)，電(dian)(dian)阻(zu)(zu)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)是一(yi)(yi)種將被測件上(shang)的壓(ya)(ya)(ya)力(li)轉換成(cheng)為(wei)(wei)一(yi)(yi)種電(dian)(dian)信號的敏感器(qi)(qi)件。電(dian)(dian)阻(zu)(zu)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)應(ying)(ying)用(yong)多的是金(jin)屬(shu)電(dian)(dian)阻(zu)(zu)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)和半導(dao)體(ti)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)兩(liang)(liang)種。金(jin)屬(shu)電(dian)(dian)阻(zu)(zu)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)又(you)有絲(si)狀應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)和金(jin)屬(shu)箔(bo)狀應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)兩(liang)(liang)種。通(tong)常是將應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)通(tong)過特殊(shu)的黏合劑緊密地(di)粘(zhan)合在(zai)(zai)產生(sheng)(sheng)(sheng)力(li)學應(ying)(ying)變(bian)(bian)(bian)基體(ti)上(shang)，當(dang)基體(ti)受力(li)發生(sheng)(sheng)(sheng)應(ying)(ying)力(li)變(bian)(bian)(bian)化時，電(dian)(dian)阻(zu)(zu)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)也(ye)一(yi)(yi)起產生(sheng)(sheng)(sheng)形(xing)變(bian)(bian)(bian)，使(shi)(shi)應(ying)(ying)變(bian)(bian)(bian)片(pian)(pian)(pian)(pian)(pian)的阻(zu)(zu)值(zhi)發生(sheng)(sheng)(sheng)改變(bian)(bian)(bian)，從而使(shi)(shi)加在(zai)(zai)電(dian)(dian)阻(zu)(zu)上(shang)的電(dian)(dian)壓(ya)(ya)(ya)發生(sheng)(sheng)(sheng)變(bian)(bian)(bian)化。

德國寶德BURKERT壓力變送器優點：
1、壓力變送器具(ju)有工作可靠、性(xing)能(neng)穩定等特點；

2、V/I集成電路，外圍器件少，可靠性高，維護簡單、輕松，體積小、重量輕，安裝調試極為方便；
3、鋁合金壓鑄外殼，三端隔離，靜電噴塑保護層，堅固耐用；
4、4-20mA DC二線制信號傳送，抗干擾能力強，傳輸距離遠；
5、LED、LCD、指針三種指示表頭，現場讀數十分方便。可用于測量粘稠、結晶和腐蝕性介質；
6、高準確(que)度(du)，高穩(wen)定性(xing)(xing)。除(chu)進口原裝傳感器已用(yong)激光修正外，對整機在使用(yong)溫度(du)范圍內的綜合性(xing)(xing)溫度(du)漂移、非線性(xing)(xing)進行精細補償。
