PARKER派克氣缸GDC50-300 3/8電流I2l的方向從T2流向T1。由特性曲線可知，這時雙向可控硅觸發(fā)導(dǎo)通規(guī)律是按第二象限的特性進(jìn)行的，又因為觸發(fā)信號是正向的，所以把這種觸發(fā)叫做“象限的正向觸發(fā)”或稱為I+觸發(fā)方式。(2)如果主電極T2仍加正向電壓，而把觸發(fā)信號改為反向信號(圖5b)，這時雙向可控硅觸發(fā)導(dǎo)通后，通態(tài)電流的方向仍然是從T2到T1。我們把這種觸發(fā)叫做“象限的負(fù)觸發(fā)”或稱為I-觸發(fā)方式。(3)兩個主電極加上反向電壓U12(圖5c)，輸入正向觸發(fā)信號，雙向可控硅導(dǎo)通后，通態(tài)電流從T1流向T2。雙向可控硅按第三象限特性曲線工作，因此把這種觸發(fā)叫做Ⅲ+觸發(fā)方式。(4)兩個主電極仍然加反向電壓U12，輸入的是反向觸發(fā)信號(圖5d)。

PARKER派克電磁閥PHS510P-6-24V-L 1/8光纖水位計光纖水位計包括水位計傳感器部分和控制電路終端部分。其中，水位計傳感器部分采用光路耦合調(diào)節(jié)設(shè)備與光纜連接用于傳遞承載水位信息的光信號，控制電路終端部分采用激光調(diào)制技術(shù)，發(fā)送不同功能的調(diào)制激光信號，通過調(diào)制、對比與檢測，獲得水位的準(zhǔn)確信息。這一原理實現(xiàn)了全程光測量，在室外不使用任何帶電器件，可以杜絕靜電危害防止雷電擊毀。跟蹤式水位計又稱接觸式水位計，利用重錘上的電測針接觸水面發(fā)出電信號，使電機(jī)正轉(zhuǎn)或逆轉(zhuǎn)，隨時跟蹤水面點(diǎn)的位置，從而測定水位。一般在較陡岸坡上架設(shè)鐵管，懸錘和懸索在管道中升降，驅(qū)動記錄或訊號裝置。鐵管進(jìn)水口需有沉沙和靜水設(shè)施。壓力式水位計它的工作原理是測量水壓力，推算水位。其特點(diǎn)是不需建靜水測井。
