  • Readings are accurate, repeatable and interference free
  • Taking readings is simple, fast and error free
  • Optional higher 15V excitation ensures quality readings for sensors with long cables

Operation
The operation of VWread is driven by the onboard menu. The main menu gives access to all VWread functions, including:
  • READ – take a reading of the VW sensor currently connected to VWread.
  • SENSOR SETUP – configure sensor reading parameters such as sweep range, frequency units, temperature units and excitation voltage.
  • DEVICE SETUP – configure display parameters, such as contrast, backlight and auto off.
  • DEVICE INFO – displays the info of the device, such as firmware version, battery voltage and board temperature.

Application
The VWread can be used to read Vibrating Wire sensors for geotechnical and structural monitoring.

Typical applications include:
  • Pore pressure monitoring
  • Water level monitoring
  • Strain monitoring
  • Displacement monitoring
  • Crack monitoring
  • Load monitoring
  • Pressure cell monitoring
