靜壓式靜力(li)水(shui)準(zhun)儀(yi)是(shi)監測(ce)(ce)工程沉(chen)降系(xi)統中的(de)重要底層監測(ce)(ce)傳感(gan)器(qi)；靜力(li)水(shui)準(zhun)測(ce)(ce)量(liang)系(xi)統是(shi)通(tong)(tong)過測(ce)(ce)量(liang)兩點間(jian)或(huo)多點間(jian)液(ye)面沉(chen)降相(xiang)對液(ye)面高(gao)度(du)變化的(de)精(jing)密儀(yi)器(qi)。主(zhu)要用(yong)于大壩、核電站(zhan)、風力(li)電站(zhan)、高(gao)層建筑、礦山、滑坡、橋(qiao)梁(liang)等(deng)(deng)垂直位(wei)移和傾(qing)斜的(de)監測(ce)(ce)。靜力(li)水(shui)準(zhun)系(xi)統一般安裝在被測(ce)(ce)物體(ti)等(deng)(deng)高(gao)的(de)測(ce)(ce)墩（基臺）上或(huo)被測(ce)(ce)物體(ti)墻壁等(deng)(deng)高(gao)線(xian)上，通(tong)(tong)常(chang)采用(yong)模塊化自動測(ce)(ce)量(liang)單元采集數(shu)據，通(tong)(tong)過有線(xian)或(huo)無線(xian)通(tong)(tong)訊與計算機連接，從(cong)而實現自動化觀測(ce)(ce)。

工作原理：靜力水準儀的(de)貯液(ye)容(rong)(rong)器(qi)相互用(yong)通(tong)液(ye)管(guan)*連通(tong)，貯液(ye)容(rong)(rong)器(qi)內(nei)注(zhu)入液(ye)體(ti)，當液(ye)體(ti)液(ye)面*靜止(zhi)后系(xi)統(tong)中所(suo)有(you)連通(tong)容(rong)(rong)器(qi)內(nei)的(de)液(ye)面應(ying)在同一(yi)個(ge)大地水準面上(shang)，此(ci)時每一(yi)容(rong)(rong)器(qi)的(de)液(ye)位由傳(chuan)感器(qi)測出差異(yi)沉降。

測量原理

設(she)傳感(gan)器的測(ce)量范圍為(wei)0～1000mmH2O，基準(zhun)點與液(ye)箱的液(ye)面高度差值為(wei)800mm，液(ye)體介(jie)質為(wei)：水，密度按(an)1代(dai)入，則1000mmH2O產(chan)生(sheng)的壓力為(wei)9.8KPa；基準(zhun)點固定(ding)不變(bian)，則基準(zhun)點傳感(gan)器檢測(ce)出液(ye)位高度帶(dai)來的壓力值為(wei)7.84KPa，通過數(shu)據中(zhong)心轉換(huan)顯(xian)示液(ye)位高度值：800mmH2O，此數(shu)據為(wei)基準(zhun)參考數(shu)值；
