          設備介紹:                                                                                        

          MultiNet?是世界頂級的浮游生物自動采樣器,它可以在連續的水層中進行水平采樣和垂直采樣。每個MultiNet?安裝5只(9只)網袋。開口面積:Mini型,0.125m2;Midi型,0.25m2,Maxi型,0.5m2;Mammoth型,1m2。整個系統由甲板控制單元、水下控制單元、不銹鋼框架、網衣、網底管等組成,5(9)只網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

          高強度彈簧提供網口開閉的動力

          鈦合金倉內的高精度步進馬達和控制單元


          網袋的開啟與關閉是通過一個電池驅動的馬達單元激發的??刂凭W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的。我們可以提供各種網袋,適用于各種標準的和非標準的應用場合。對于常規的水平采樣操作,我們推薦您使用孔徑為300微米(孔徑從100微米至500微米都是可選的)的網袋;對于垂直采樣來說,網孔大小從55微米到500微米都是適用的。

          水下單元中集成一個壓力傳感器,深度和所有其他系統相關數據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口流量計:一個裝在水下單元的開口內,用于測定通過網口的水量;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底管固定器上,以便垂直采樣時,采樣網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?上的所有網袋是關閉的。水流可以很自由地流過框架,并允許采樣器以最適合的速度降到最期望的深度,然后按下甲板單元上的按鈕,可以使第一個網袋打開,當操作結束時,可以通過第二個指令將其關閉。在第一個網袋關閉的同時,第二個網袋會接著打開,當甲板單元顯示激活的網袋號碼時,這些網袋會重復以上過程。在操作Mini型和Midi型MultiNet?t時,第5個網袋保持敞開狀態,它會收集從最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個網袋可以在到達水面之前閉合。

          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UNESCO公式,系統可以從獲得的CTD數據,計算出鹽度、密度和聲速等指標。


          額外選擇:
          √各種參數的傳感器,如鹽度、溫度、葉綠素a、濁度、姿態傳感器等

          √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6000米和11000米采樣的特殊型號
