• 
  Earth Pressure Cell

  4800X: The custom Model 4800 Earth Pressure Cell shown here has a 100mm diameter and was designed for use in large scale laboratory tests. The cell consists of two stainless steel plates welded around their periphery and spaced by a narrow cavity filled with de-aired oil. Changing pressure squeezes the plates together, increasing the pressure inside. The pressure is measured by a Vibrating Wire Pressure Transducer, whose output is transmitted to a readout or datalogger.

• 
  Deformation Meter

  4430X: The Model 4430 Deformation Meter is designed to measure longitudinal deformation in dams and embankments. The custom version shown here is 0.5m in length and has a 100mm range. It comprises a Vibrating Wire Displacement Transducer, connected between two end flanges, and protected by a sturdy PVC housing with a built-in telescopic coupling. The end flanges enable a series of sensors to be bolted together allowing complete profiles of deformation to be measured.

• 
  Instrumented Rockbolts

  4910X: The Model 4910 shown here comprises a Threadbar in which a miniature Vibrating Wire Strain Gauge has been installed along a bore at the head of the bolt. The instrumented rock bolt is installed in the same manner as conventional rockbolts, in this case by rupturing a resin cartridge and spinning. The built-in connector, at the head of the bolt, allows the readout cable to be conveniently attached after installation.
