智能型數顯壓力傳感器分為 擴散(san)硅(gui)壓(ya)力變送(song)(song)器(qi)芯體(ti)(ti)和 電(dian)容(rong)壓(ya)力變送(song)(song)器(qi)芯體(ti)(ti)。擴散(san)硅(gui)壓(ya)力變送(song)(song)器(qi)具(ju)有工作可靠、性能穩定、安裝使用方便、體(ti)(ti)積小(xiao)、重量輕、性能價格比高(gao)等點，能在(zai)各種(zhong)正負(fu)壓(ya)力測量中得到(dao)廣(guang)泛應用。

壓(ya)(ya)力(li)傳(chuan)感器(qi)(qi)(qi)兩(liang)(liang)線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)比(bi)較(jiao)簡單，一般(ban)客戶都知道怎么接(jie)(jie)線(xian)(xian)(xian)(xian)(xian)，一根(gen)線(xian)(xian)(xian)(xian)(xian)連(lian)接(jie)(jie)電(dian)源(yuan)(yuan)正極(ji)，另一個(ge)線(xian)(xian)(xian)(xian)(xian)也就(jiu)(jiu)是(shi)信(xin)(xin)號(hao)線(xian)(xian)(xian)(xian)(xian)經過儀(yi)(yi)器(qi)(qi)(qi)連(lian)接(jie)(jie)到(dao)(dao)電(dian)源(yuan)(yuan)負極(ji)，這種是(shi)的(de)(de)(de)，壓(ya)(ya)力(li)傳(chuan)感器(qi)(qi)(qi)三(san)線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)是(shi)在兩(liang)(liang)線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)基礎上(shang)加(jia)了(le)一個(ge)線(xian)(xian)(xian)(xian)(xian)，這根(gen)線(xian)(xian)(xian)(xian)(xian)直接(jie)(jie)連(lian)接(jie)(jie)到(dao)(dao)電(dian)源(yuan)(yuan)的(de)(de)(de)負極(ji)，較(jiao)兩(liang)(liang)線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)麻煩一點。四線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)壓(ya)(ya)力(li)傳(chuan)感器(qi)(qi)(qi)肯(ken)定(ding)是(shi)兩(liang)(liang)個(ge)電(dian)源(yuan)(yuan)輸(shu)入端(duan)，另外兩(liang)(liang)個(ge)是(shi)信(xin)(xin)號(hao)輸(shu)出(chu)端(duan)。四線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)的(de)(de)(de)多半(ban)是(shi)電(dian)壓(ya)(ya)輸(shu)出(chu)而不是(shi)4~20mA輸(shu)出(chu)，4~20mA的(de)(de)(de)叫壓(ya)(ya)力(li)變送(song)器(qi)(qi)(qi)，多數做成兩(liang)(liang)線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)的(de)(de)(de)。壓(ya)(ya)力(li)傳(chuan)感器(qi)(qi)(qi)的(de)(de)(de)信(xin)(xin)號(hao)輸(shu)出(chu)有些(xie)是(shi)沒有經過放(fang)(fang)大(da)的(de)(de)(de)，滿(man)量程輸(shu)出(chu)只(zhi)有幾十毫伏，而有些(xie)壓(ya)(ya)力(li)傳(chuan)感器(qi)(qi)(qi)在內部有放(fang)(fang)大(da)電(dian)路，滿(man)量程輸(shu)出(chu)為0~2V。至于怎么接(jie)(jie)到(dao)(dao)顯示儀(yi)(yi)表，要(yao)看(kan)儀(yi)(yi)表的(de)(de)(de)量程是(shi)多大(da)，如(ru)果有和輸(shu)出(chu)信(xin)(xin)號(hao)相適應的(de)(de)(de)檔位，就(jiu)(jiu)可以直接(jie)(jie)測量，否則要(yao)加(jia)信(xin)(xin)號(hao)調整電(dian)路。五線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)壓(ya)(ya)力(li)傳(chuan)感器(qi)(qi)(qi)與四線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)相差不大(da)，市面上(shang)五線(xian)(xian)(xian)(xian)(xian)制(zhi)(zhi)的(de)(de)(de)傳(chuan)感器(qi)(qi)(qi)也比(bi)較(jiao)少

智能型數顯壓力傳感器優點

具有強大(da)(da)的界(jie)面操作(zuo)功能，數(shu)字表頭(tou)可(ke)(ke)以(yi)顯示壓(ya)力(li)、百分比和(he)電流，及(ji)0～100%模擬指(zhi)示，可(ke)(ke)以(yi)就地顯示極大(da)(da)的方便(bian)了現場(chang)作(zuo)業，按鍵操作(zuo)能方便(bian)地在無(wu)標準壓(ya)力(li)源的情況下完成(cheng)零點遷(qian)移、量程設(she)(she)定、阻尼設(she)(she)定等(deng)基本參數(shu)的設(she)(she)置，極大(da)(da)的方便(bian)了現場(chang)調(diao)試。另外其(qi)多功能的信號(hao)輸(shu)出解決了信號(hao)遠(yuan)程采(cai)集和(he)操控的煩惱，信號(hao)可(ke)(ke)以(yi)遠(yuan)傳長(chang)達幾(ji)百米。

使用方法

壓電式壓力傳感器：

壓(ya)電效應是壓(ya)電傳感(gan)器的(de)主要工作(zuo)(zuo)原理，壓(ya)電傳感(gan)器不能用于靜態測量(liang)，因為經過外力作(zuo)(zuo)用后的(de)電荷，只有在回路具有無限(xian)大(da)的(de)輸入阻(zu)抗(kang)時才得到保存。實際(ji)的(de)情況不是這樣的(de)，所以這決定(ding)了壓(ya)電傳感(gan)器只能夠測量(liang)動態的(de)應力。

以真空為(wei)標準表示的壓力大小。

接線方法
傳感器的接線一向是客戶采購過程咨詢得多的問題之一，很多客戶都不知道傳感器如何連線，其實各種傳感器的接線方式基本都是一樣的，壓力傳感器一般有兩線制、三線制、四線制，有的還有五線制的。
壓(ya)力(li)傳感器兩(liang)(liang)線(xian)(xian)制(zhi)比較簡單，一般客(ke)戶都知(zhi)道怎么接線(xian)(xian)，一根線(xian)(xian)連(lian)接電源(yuan)(yuan)正極，另一個(ge)線(xian)(xian)也就是(shi)信號線(xian)(xian)經(jing)過儀(yi)器連(lian)接到電源(yuan)(yuan)負(fu)極，這種的，壓(ya)力(li)傳感器三線(xian)(xian)制(zhi)是(shi)在兩(liang)(liang)線(xian)(xian)制(zhi)基礎上加了一個(ge)線(xian)(xian)，這根線(xian)(xian)直接連(lian)接到電源(yuan)(yuan)的負(fu)極，較兩(liang)(liang)線(xian)(xian)制(zhi)麻煩一點。
