Hydraulic Earth Pressure Cell


The Model 2000 Hydraulic Earth Pressure Cell is fluid filled and connected to any of the series 1000 diaphragm piezometers, which act as the pressure transducer (see model 1100 and 1200 for details). The cells are suitable for measurement of total pressure against walls and in embankments, fills and any other earthen mass. The Model 2050 is similar to the 2000 but is fitted with a post stressing pinch tube, which allows recoupling of the cell to concrete after curing.


Hydraulic Earth Pressure Cells are designed to measure stress acting on a plane surface and are typically installed in:

  • Dams and earth embankments
  • Foundations, retaining walls and piles
  • Against pipelines and culverts
  • Against and under buildings
  • In railroad ballast
  • Beneath raft foundations
  • Paste backfills


  • Long term stability
  • High accuracy and sensitivity
  • Simple installation
  • Can tolerate long cable lengths
  • Waterproof design
  • Fitted with thermistor
  • Due to inherent high sensitivity it is not necessary to produce a large strain in the area monitored to create stress.
  • Able to be connected to data logging systems


  • Pressure ranges: (kPa) 350, 700, 1000, 2000, 3000, 5000
  • Accuracy: <± 0.5% full scale
  • Resolution: 0.025% full scale
  • Operating temperature: -20 to +65C
  • Connecting tube length: 300mm
  • Dimension: 230mm, 20mm thick
  • Weight: 1.8 kg
