Extensometer

An Extensometer is a geotechnical monitoring instrument that is designed to help civil engineers and geologists in the measurement of the deformation of the rock mass and adjacent or surrounding soil.

Description:

The extensometer allows for measurements of precise longitudinal dis-placements in rock, soil and concrete structures. Typically it is used for monitoring settlement in foundations, subsidence above tunnels, displacements of retaining structures, and deformations in underground openings.

Key Features:
  • Rugged construction
  • Mechanical, electrical, or both reading
  • Stainless steel or fiberglass rods
  • Protective sleeve on rods
  • Many anchors available
Applications:
  • Bearing measurements of precise longitudinal displacements in rock, soil and concrete structures
  • Deformation of laterally loaded piles and sheet piles
  • Monitoring settlement in foundations,
  • Displacements of retaining structures
  • Deformations in underground openings
