4-20m4-20mA壓力變送器特點：

     -100KPa...0…1...350bar壓力范(fan)圍測量

     多(duo)種工業標準信號輸(shu)出(chu)可選(xuan)

     接線(xian)方式為連接器或直接引線(xian)

     簡潔的外形(xing)設(she)計(ji)，性(xing)價比高

     可(ke)按要求(qiu)增加調零調滿度功能

     多種壓力接口可選擇

優點

1、壓力變送器具有工(gong)作可靠(kao)、性能穩(wen)定(ding)等特(te)點；

2、專用V/I集(ji)成(cheng)電路，外圍器(qi)件少，可靠性高，維護簡單、輕松，體積小(xiao)、重(zhong)量輕，安裝調試極為(wei)方便；

3、鋁合(he)金壓(ya)鑄外殼，三端隔離，靜電(dian)噴塑保護(hu)層，堅固(gu)耐用；

4、4-20mADC二(er)線(xian)制信號傳(chuan)送，抗(kang)干擾的能力強，傳(chuan)輸距離遠；

5、LED、LCD、指針三種指示表頭，現場(chang)讀數十分方便。可(ke)用于測量粘稠、結晶和腐蝕性介質；

工業壓力變送器

壓(ya)力(li)變(bian)(bian)送器是(shi)工業實踐中常(chang)用(yong)的一種(zhong)傳感器，其廣泛(fan)應用(yong)于(yu)各種(zhong)工業自控環境，涉及水(shui)利水(shui)電、鐵(tie)路交通、智能建筑、生產自控、航空航天、軍工、石化、油井、電力(li)、船舶、機床、管道等眾多行業。下面就簡單介紹一些常(chang)用(yong)壓(ya)力(li)變(bian)(bian)送器的原理及其應用(yong)、壓(ya)力(li)變(bian)(bian)送器是(shi)用(yong)于(yu)測量液體(ti)、氣體(ti)或蒸汽的液位、密度和壓(ya)力(li)，然后將壓(ya)力(li)信號轉變(bian)(bian)成4～20mADC信號輸(shu)出(chu)。

壓力(li)變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)主要有電容式壓力(li)變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)和(he)擴散硅壓力(li)變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)，陶瓷壓力(li)變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)，應(ying)變(bian)(bian)(bian)(bian)式壓力(li)變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)等。壓力(li)變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)根據測(ce)壓范圍可分成一般壓力(li)變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)（0.001MPa～35MPa）和(he)微差壓變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)（0～1.5kPa），負壓變(bian)(bian)(bian)(bian)送(song)(song)器(qi)(qi)三(san)種。
