智能壓力變送器型號

壓(ya)(ya)(ya)(ya)力(li)變(bian)送(song)器的(de)主要作用(yong)把壓(ya)(ya)(ya)(ya)力(li)信號傳到(dao)電(dian)(dian)(dian)(dian)子設備，進而在計(ji)算機顯示壓(ya)(ya)(ya)(ya)力(li)其(qi)原理大(da)(da)致是：將水(shui)壓(ya)(ya)(ya)(ya)這種壓(ya)(ya)(ya)(ya)力(li)的(de)力(li)學(xue)信號轉變(bian)成電(dian)(dian)(dian)(dian)流(liu)（4-20mA）這樣(yang)的(de)電(dian)(dian)(dian)(dian)子信號壓(ya)(ya)(ya)(ya)力(li)和(he)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)或(huo)電(dian)(dian)(dian)(dian)流(liu)大(da)(da)小成線性關系(xi)，一(yi)般是正比關系(xi)。所以，變(bian)送(song)器輸出(chu)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)或(huo)電(dian)(dian)(dian)(dian)流(liu)隨壓(ya)(ya)(ya)(ya)力(li)增大(da)(da)而增大(da)(da)由此得出(chu)一(yi)個壓(ya)(ya)(ya)(ya)力(li)和(he)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)或(huo)電(dian)(dian)(dian)(dian)流(liu)的(de)關系(xi)式壓(ya)(ya)(ya)(ya)力(li)變(bian)送(song)器的(de)被測介質的(de)兩(liang)種壓(ya)(ya)(ya)(ya)力(li)通入(ru)高、低兩(liang)壓(ya)(ya)(ya)(ya)力(li)室，低壓(ya)(ya)(ya)(ya)室壓(ya)(ya)(ya)(ya)力(li)采用(yong)大(da)(da)氣(qi)壓(ya)(ya)(ya)(ya)或(huo)真空，作用(yong)在δ元(yuan)（即敏感(gan)元(yuan)件(jian)）的(de)兩(liang)側隔離膜片(pian)上，通過隔離片(pian)和(he)元(yuan)件(jian)內的(de)填充(chong)液傳送(song)到(dao)測量(liang)膜片(pian)兩(liang)側。

產品特點:
或稱智能壓力變送器用于測量液體、氣體或蒸汽的液位、密度和壓力，然后將其轉變成4～20mA DC信號輸出。3051壓力變送器可與HART手操器相互通訊，通過它進行設定，監控。智能型液晶表頭采用智能按鍵可修改量程、顯示單位、溫度等等,（智能）壓力變送器過壓強度高，穩定性好。輸入量程為0～0.25KPa，0～10KPa，0～40KPa。
