Overview

The PVS5120C is a composite sampler that deposits its water samples into a nine-liter container. This sampler uses a vacuum sampler controller, the VSC100, to allow a Modbus RTU client, SDI-12 client device, simple pulse input, or Campbell Scientific PakBus data logger to control and communicate with the water sampler.

This sampler is lightweight, portable, and battery-powered. It can fit in a small-sized manholeand be suspended by a stainless-steel harness for sewer applications.

PVS5120C可与标准或大型泵一起使用。标准泵以1.6 m / s（5.1ft / s）的样品为7.6米（25英尺）的水平绘图。大型泵在7.6米（25英尺）的2.2m / s（7.1ft / s）下采样。这些速度都是海平面测量的典型值。随着高度的增加，进气速度将减少。

Diagnostic feedback provided to the client device: bottle number, sample number, response code/message, sampler battery voltage
Auto deploy that automatically sets the purge and vacuum times based on hose length
Repeatable volume collection via metering chamber
Selectable internal or external power via three-way power switch
所有控制类型的一个控制电缆
An optional water present sensor detects the presence of water at the mouth of the sampler intake hose to ensure a sample is available

Detailed Description

The PVS5120C uses an external vacuum pump to draw water through intake tubing, instead of the traditional peristaltic pump that induces flow by squeezing flexible tubing. Because the vacuum method disturbs the water samples less, they better represent the original water solution, especially if the solution has high concentrations of supsended solids.

为了防止交叉污染，采样器使用气压（最多28psi）来吹扫多余水的管道。标准泵可以高达大型泵，适用于大多数应用 - 特别是当电力预算是一个问题时。大型泵适用于长软管距离或高升降机的应用，因为它提供了更高的泵送速度。
