Overview

PVS5120C CAMPBELL SAMPLER COMPOSITE PORTABLE DC AUTOMATIC LIQUID SAMPLER

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 manhole and be suspended by a stainless-steel harness for sewer applications. 

The PVS5120C can be used with a standard or large pump. The standard pump takes samples at 1.6 m/s (5.1 ft/s) for horizontal draws of 7.6 m (25 ft). The large pump takes samples at 2.2 m/s (7.1 ft/s) at 7.6 m (25 ft). Both of these velocities are typical values measured at sea level. Intake velocities will decrease as altitude increases. 

Key Advantages

Sampler Optimized for Data Logger or RTU Control
Vacuum technology for better samples

Technical 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. 

To prevent cross contamination, the sampler uses air pressure (up to 28 psi) to purge the tubing of excess water. The standard pump can lift as high as the large pump and is appropriate for most applications─especially when the power budget is a concern. The large pump is appropriate for applications with long hose distances or high lifts because it provides higher pumping velocity. 

Benefits

  • 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
  • One control cable for all control types
  • An optional water present sensor detects the presence of water at the mouth of the sampler intake hose to ensure a sample is available
