設備介紹
MultiNet®是世界**的浮游生物自動采樣器,它可以在連續(xù)的水層中進行水平采樣和垂直采樣。每個MultiNet®安裝5只(9只)網(wǎng)袋。開口面積:Mini型,0.125m2;Midi型,0.25m2,Maxi型,0.5m2;Mammoth型,1m2。整個系統(tǒng)由甲板控制單元、水下控制單元、不銹鋼框架、網(wǎng)衣、網(wǎng)底管等組成,5(9)只網(wǎng)袋通過拉鏈連接器連接在不銹鋼框架的帆布部分上。
每次可采5(9)個水層樣品準備入水高強度彈簧提供鈦合金倉內(nèi)的高精度
網(wǎng)口開閉的動力步進馬達和控制單元
網(wǎng)袋的開啟與關閉是通過一個電池驅動的馬達單元激發(fā)的。控制網(wǎng)袋開關的指令時通過甲板控制單元和水下單元之間的單芯和多芯電纜傳輸?shù)?。我們可以提供各種網(wǎng)袋,適用于各種標準的和非標準的應用場合。對于常規(guī)的水平采樣操作,我們推薦您使用孔徑為300um(孔徑從100um至500um都是可選的)的網(wǎng)袋;對于垂直采樣來說,網(wǎng)孔大小從55um到500um都是適用的。
水下單元中集成一個壓力傳感器,深度和所有其他系統(tǒng)相關數(shù)據(jù)會一起在甲板控制單元的液晶顯示屏上顯示。水下單元上可以安裝兩個帶有角度補償功能的電子網(wǎng)口流量計:一個裝在水下單元的開口內(nèi),用于測定通過網(wǎng)口的水量;另一個裝在水下單元開口外,用于測定“堵塞效應”。在水平采樣操作中,MultiNet®安裝了一個V-Fin深度抑制器;在垂直采樣操作時,一個不銹鋼支撐安裝在網(wǎng)底管固定器上,以便垂直采樣時,采樣網(wǎng)能夠安全迅速地降到所需的深度。
操作
在初始位置的時候,MultiNet®上的所有網(wǎng)袋是關閉的。水流可以很自由地流過框架,并允許采樣器以*適合的速度降到*期望的深度,然后按下甲板單元上的按鈕,可以使**個網(wǎng)袋打開,當操作結束時,可以通過第二個指令將其關閉。在**個網(wǎng)袋關閉的同時,第二個網(wǎng)袋會接著打開,當甲板單元顯示激活的網(wǎng)袋號碼時,這些網(wǎng)袋會重復以上過程。在操作Mini型和Midi型MultiNet®t時,第5個網(wǎng)袋保持敞開狀態(tài),它會收集從*淺期望深度到表層的浮游生物。在操作Maxi型和Mammoth型MultiNet®時,第9個網(wǎng)袋可以在到達水面之前閉合。
MultiNet入水姿態(tài)MultiNet整裝待發(fā)
CT組件MultiNet®與CT組件結合在一起,擁有一臺CTD(溫鹽深儀)的完整功能。CT組件由一個電導率傳感器,一個溫度傳感器和一塊附加電路板組成,它們集成在MultiNet®的馬達驅動單元中。根據(jù)UNESCO公式,系統(tǒng)可以從獲得的CTD數(shù)據(jù),計算出鹽度、密度和聲速等指標。
額外選擇√各種參數(shù)的傳感器,如鹽度、溫度、葉綠素a、濁度、姿態(tài)傳感器等
√電池供電的手持終端,當在線操作沒有交流電供電時,用來代替甲板控制單元√適用于6000m和11000m采樣的特殊型號
