    按傳感器原理分浮子式、跟蹤式、壓力式和反射式等。水位記錄主要有:記錄紙描述,數(shù)據(jù)顯示或打字記錄,穿孔紙帶,磁帶和固體電路儲存等。水位計的度一般在1~3厘米以內(nèi),制造的水位計的記錄周期有1天、30天和90天等。走時誤差,機械鐘為2分/日,石英晶體鐘小于5分/月。分類浮子式水位計其原理是由浮子感應(yīng)水位的升降。有用機械直接使浮子傳動記錄結(jié)構(gòu)的普通水位計,有把浮子提供的轉(zhuǎn)角量轉(zhuǎn)換成增量電脈沖或二進制編碼脈沖作遠距離傳輸?shù)碾妭、?shù)傳水位計,還有用微型浮子和許多干簧管組成的數(shù)字傳感水位計等。應(yīng)用較廣的是機械式水位計。應(yīng)用浮子式水位計需有測井設(shè)備,只適合于岸坡、河床沖淤很小的低含沙量河段使用。測井見圖1。如果VS的控制極沒有輸入觸發(fā)脈沖Ug,VS仍然不能導(dǎo)通,只有在U2處于正半周,在控制極外加觸發(fā)脈沖Ug時,晶閘管被觸發(fā)導(dǎo)通。畫出它的波形(c)及(d),只有在觸發(fā)脈沖Ug到來時,負載RL上才有電壓UL輸出。Ug到來得早,晶閘管導(dǎo)通的時間就早;Ug到來得晚,晶閘管導(dǎo)通的時間就晚。通過改變控制極上觸發(fā)脈沖Ug到來的時間,就可以調(diào)節(jié)負載上輸出電壓的平均值UL。在電工技術(shù)中,常把交流電的半個周期定為180°,稱為電角度。這樣,在U2的每個正半周,從零值開始到觸發(fā)脈沖到來瞬間所經(jīng)歷的電角度稱為控制角α;在每個正半周內(nèi)晶閘管導(dǎo)通的電角度叫導(dǎo)通角θ。很明顯,α和θ都是用來表示晶閘管在承受正向電壓的半個周期的導(dǎo)通或范圍的。SCONINC變換器SCONI-ACC-B86X,出售山一SKC-18MP
