详细介绍
MultiNet浮游生物连续采样网
Multi Plankton Sampler MultiNet
垂直操作状态 水平操作状态MultiNet是世界顶级的浮游生物自动采样器,它可以在连续的水层中进行水
平采样和垂直采样。每个MultiNet安装有5只(9只)3种不同孔径的网袋:
Mini型,0.125m2;Midi型,0.25m2,和Maxi型,0.5m2。整个系统由甲板控制单元和一个不锈钢框架组成,5(9)只网袋通过拉链
连接器连接在不锈钢框架的帆布部分上。网袋的开启与关闭是通过一个电池驱动的马达单元激发的。控制网袋开关的
指令时通过甲板控制单元和水下单元之间的单芯和多芯电缆传输的。我们可
以提供各种网袋,适用于各种标准的和非标准的应用场合。对于常规的水平
采样操作,我们推荐您使用孔径为300微米(孔径从100微米至500微米都
是可选的)的网袋;对于垂直采样来说,网孔大小从55微米到500微米都是
适用的。水下单元中集成一个压力传感器,深度和所有其他系统相关数据会一起在甲
板控制单元的液晶显示屏上显示。水下单元上可以安装两个带有角度补偿的功能的电子网口流量计:一个装在
水下单元的开口内,用于测定通过网口的水量;另一个装在网口开口外,用
于测定“堵塞效应”。在水平采样操作中,MultiNet安装了一个V-Fin深度抑制器;在垂直采样操作
时,一个不锈钢支撑安装在网筒固定器上,以便垂直采样时,采样网能够安
全迅速地降到所需的深度。操作
在初始位置的时候,MultiNet上的所有网袋是关闭的。水流可以很自由地流过
框架,并允许采样器以最适合的速度降到最期望的深度,然后按下甲板单元上
的按钮,可以使第一个网袋打开,当操作结束时,可以通过第二个指令将其关
闭。在第一个网袋关闭的同时,第二个网袋会接着打开,当甲板单元显示激活
的网袋号码时,这些网袋会重复以上过程。在操作Mini型和Midi型MultiNet时,
第5个网袋保持敞开状态,它会收集从最浅期望深度到表层的浮游生物。在操
作Maxi型MultiNet时,第9个网袋可以在到达水面之前闭合。离线组件
在电缆无法获得情况下,我们可以给您提供一个离线组件,可以通过PC机对采
样深度进行预编程。安装这个离线组件后,网袋的开合可以根据预先选择好的
深度间隔自动进行。在操作过程中,所有的测量数据都会存储到离线组件中,当
操作结束时,这些数据可以下载到PC机上进行处理。CT组件
MultiNet与CT组件结合在一起,拥有一台CTD(温盐深仪)的完整功能。
CT组件由一个电导率传感器,一个温度传感器和一块附加电路板组成,它们集成
在MultiNet的马达驱动单元中。根据UNESCO公式,系统可以从获得的CTD数据,
计算出盐度、密度和声速等指标。额外选择
