Visão Geral

The PVS4100C is a deluxe ac-powered only water sampler that deposits its water samples into one container. It uses a bigger sampler pump, allowing it to support the fastest sampling rates and longest sampling distances. The PVS4100C includes a programmable controller with 16-key intuitive touch pad. The controller can accept a pulse input (e.g., rain gage), a 4 to 20 mA signal (e.g., flow meter), or initiate a sample on a timed basis. The sampler can also be interfaced with our data loggers to measure a variety of sensors, as well as control the sampler based on time, event, or measured conditions.

Vacuum technology benefits over peristaltic pump samplers:

  • Accurate sample volumes
  • Rapid transport velocities mean more-representative samples
  • Less disturbance of sample
  • Minimal wear on the tubing, resulting in less-frequent maintenance
  • Reduced cross-sample contamination

Descrição Técnica

The PVS4100C is designed for ac applications only. The PVS4100C uses an external vacuum pump to draw water through intake tubing, instead of the traditional peristaltic pump that induce flow by squeezing flexible tubing. Advantages of the vacuum pump method include faster sampling rates, longer sampling distances, and less maintenance. Because the vacuum method disturbs the water samples less, they better represent the original water solution, especially if the solution has high concentrations of suspended solids. To prevent cross contamination, the sampler use air pressure (up to 28 psi) to purge the tubing of excess water.

The enclosure of the PVS4100C is a molded medium-density linear polyethylene, designed to handle tough environmental challenges and weathering. Its hub has an insulated ring and a cavity for crushed ice, giving more control over the temperature of the sample.

Controller

The PVS4100C 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.
