概览
PVS4100D 是一款高级的交流供电的分离式水采样器，抽取水样到24个容量瓶中。它使用我们最大的采样泵，能够支持最快的采样速率和最长的采样距离。PVS4100D 包含一个可编程的控制器，带有16-键的直观触摸板。控制器可以接受脉冲输入（例如：雨量筒）、4到20 mA信号（例如：流量计）或基于时间来初始化采样。控制器还可以接入我们的数据采集器，测量多种传感器，同样可以基于时间、事件或测量的条件来控制采样器。
优势与特点
- Bigger pump allows it to support faster sampling rates and longer sampling distances
- Side handles for easy lifting (increases diameter)
- Handcart available for easy transport
- Stainless-steel suspension harness offered for sampling in sewer systems
- Interfaces with Campbell Scientific data loggers for more measurement and control capabilities

技术说明
PVS4100D 使用外部真空泵，抽取水样流过采样管，而不是使用蠕动泵将水样轧入软管。真空泵方法的优点包括更快的采样速率和更长的采样距离，以及更少的维护。因为真空方法对水样扰动更小，因此采集的水样更能代表原始的水体溶液，特别是高浓度悬浮固体的溶液。为了防止交叉污染，采样器使用压缩空气（可达28 psi）来冲洗有水样流过的管路。
PVS4100D 机箱的材质是模塑的中等密度的线性聚乙烯，可忍受恶劣的环境条件和天气。它的总进样器具有一个隔离环和一个空腔，可对样品的温度提供更多的控制。

兼容性
Controller
The PVS4100D includes a programmable controller with 16-key intuitive touch pad. The controller can accept a pulse input (for example, rain gage), a 4 to 20 mA signal (for example, flow meter), or initiate a sample on a timed basis. The sampler can also be interfaced with our data loggers. Our data loggers can measure nearly any turbidity, water level, or hydrometeorological sensor, as well as control the sampler based on time, event, or measured conditions.
