數顯壓力傳感器優勢
　　壓力傳(chuan)感器兩線制比較(jiao)簡單，一般客戶(hu)都知道怎么(me)接線，一根線連(lian)接電源正(zheng)極，另一個線也就(jiu)是信號(hao)線(xian)(xian)(xian)經過(guo)儀(yi)器(qi)(qi)連(lian)(lian)接(jie)(jie)到電(dian)(dian)源負(fu)極(ji)，這(zhe)種是(shi)(shi)簡(jian)單的(de)(de)(de)(de)，壓力(li)傳(chuan)感(gan)器(qi)(qi)三線(xian)(xian)(xian)制(zhi)(zhi)是(shi)(shi)在兩線(xian)(xian)(xian)制(zhi)(zhi)基礎上(shang)(shang)加(jia)了一個(ge)線(xian)(xian)(xian)，這(zhe)根線(xian)(xian)(xian)直(zhi)接(jie)(jie)連(lian)(lian)接(jie)(jie)到電(dian)(dian)源的(de)(de)(de)(de)負(fu)極(ji)，較(jiao)兩線(xian)(xian)(xian)制(zhi)(zhi)麻煩一點。四(si)線(xian)(xian)(xian)制(zhi)(zhi)壓力(li)傳(chuan)感(gan)器(qi)(qi)肯定是(shi)(shi)兩個(ge)電(dian)(dian)源輸(shu)入端，另(ling)外兩個(ge)是(shi)(shi)信(xin)號(hao)輸(shu)出(chu)(chu)(chu)端。四(si)線(xian)(xian)(xian)制(zhi)(zhi)的(de)(de)(de)(de)多(duo)半是(shi)(shi)電(dian)(dian)壓輸(shu)出(chu)(chu)(chu)而不是(shi)(shi)4~20mA輸(shu)出(chu)(chu)(chu)，4~20mA的(de)(de)(de)(de)叫壓力(li)變送器(qi)(qi)，多(duo)數做(zuo)成(cheng)兩線(xian)(xian)(xian)制(zhi)(zhi)的(de)(de)(de)(de)。壓力(li)傳(chuan)感(gan)器(qi)(qi)的(de)(de)(de)(de)信(xin)號(hao)輸(shu)出(chu)(chu)(chu)有些是(shi)(shi)沒(mei)有經過(guo)放(fang)大的(de)(de)(de)(de)，滿量程輸(shu)出(chu)(chu)(chu)只有幾十毫(hao)伏，而有些壓力(li)傳(chuan)感(gan)器(qi)(qi)在內部有放(fang)大電(dian)(dian)路，滿量程輸(shu)出(chu)(chu)(chu)為0~2V。至于怎么接(jie)(jie)到顯示儀(yi)表，要看儀(yi)表的(de)(de)(de)(de)量程是(shi)(shi)多(duo)大，如果(guo)有和輸(shu)出(chu)(chu)(chu)信(xin)號(hao)相適(shi)應的(de)(de)(de)(de)檔位，就可以(yi)直(zhi)接(jie)(jie)測量，否則(ze)要加(jia)信(xin)號(hao)調整電(dian)(dian)路。五線(xian)(xian)(xian)制(zhi)(zhi)壓力(li)傳(chuan)感(gan)器(qi)(qi)與四(si)線(xian)(xian)(xian)制(zhi)(zhi)相差不大，市面上(shang)(shang)五線(xian)(xian)(xian)制(zhi)(zhi)的(de)(de)(de)(de)傳(chuan)感(gan)器(qi)(qi)也比較(jiao)少
