PRODUCT FEATURES:

  • Piezometers (electrical resistance or vibrating wire) are designed for accurate and long term pore water pressure measurement in fully or partially saturated soil and rock.
  • Both Vibrating Wire or Electrical Piezometers are robust, have excellent long term stability and can be used with long cable lengths without any signal degradation.
  • The piezometer comprises a porous filter tip element (high or low air entry) integral with a diaphragm type pressure transducer.
  • A cable connects the transducer to a read-out, terminal unit or data-logger and the data is then recorded and converted to engineering units.
  • Piezometers are installed in different ways depending on the application and soil condition. Typically, they are installed in fully grouted boreholes (or surrounded by a sand filter) at the desired depth (a bentonite plug may be formed above the sand filter, if present, and the remainder of the borehole is filled with a bentonite-cement grout).
  • Electrical resistance sensors output mA signal
  • Vibrating wire sensors output frequency signal

PRODUCT BENEFITS:

  • Small diameter devices, accurate and small with excellent long term stability
  • Accuracy unaffected by cable length
  • Fast response to pressure changes
  • Manufactured from high grade stainless steel for extended operation
  • Over-voltage surge arrestor fitted to protect against electrical damage
  • Hermetically sealed, ensures long working life of the instruments
  • Advanced designs prevents case stresses from affecting readings
  • Compatible with WASP and Campbell dataloggers for easy automation

TYPICAL APPLICATIONS INCLUDE:

  • Measuring slope stability
  • Safe placement rate of fill or excavation
  • Design and build for lateral or uplift pressures or buoyancy
  • Monitoring the performance of earth-fill dams and embankments
  • Monitoring groundwater, seepage and verify models of flow
  • Monitor surface water run-off and water levels at contaminated sites, etc.
