SlopeSense V1 VW Logger

SlopeSense V1 VE Logger

DGSI’s cost-effective, easy-to-install data logger system.

Typical applications include:

  • Strain in buried pipelines
  • Pore pressure in a tailings dam
  • Deformations of embankments and retaining walls
  • Landslide areas above dams, highways, and railroads to provide early warning of slope failure

Operation

The SlopeSense V1 VW Logger is simple to use and easy to set-up. After configuring your gateway, connect the logger to your computer and use the provided software to join the V1 VW Logger to the network and to specify the reading frequency.

The SlopeSense on-site set-up is simple; connect the sensor signal cables to the logger then close the logger and walk away.

Readings are transmitted from the logger to the SlopeSense gateway, from there to an ftp server (Atlas Web Monitoring subscription required).

The SlopeSense system supports your remote sensor applications in virtually any environment.

Key Features:

  • Simple to Use: Learn how to use your V-Logger in minutes, not hours.
  • Increased Accuracy: The SlopeSense V1 VW Logger continues the V-Logger’s “Best in industry for VW logging accuracy” due to a revolutionary measuring technique.
  • Reliable: Rated for temperatures from -40° to 85°C. This product is IP 65 Rated.
  • Improved Noise Reduction: The proprietary reading method reduces outside interference from telecom or electrical sources. providing cleaner, more reliable data for your project.
  • Extended Battery Life: The VW logger uses a unique algorithm for maximizing the battery life of the lithium.

SYStem Configurations
Power
One lithium D-cell battery provides power for more than 10 years in moderate temperatures, assuming readings taken every hour.
Data  Our Logger Manager software retrieves logger readings and applies calibration factors, if present, to generate data files containing both raw and processed readings.
This data can be used immediately in your spreadsheet software
