Embeddable Strain Sensor ES-01

Embeddable Strain Sensor ES-01

 

The embeddable strain sensor ES-01 is a strain sensor that is intended to become embedded into concrete structures in order to measure the strain variations between its anchoring points. The fiber is fixed inside a ruggedized housing and has a connector at both ends in order to make series configurations possible.

 

Features

  • Detection of strain with sub-microstrain precision
  • Sensors can be placed in series and hereby reducing the cabling to a minimum
  • Ruggedized housing that can be directly embedded into a concrete structure
  • Direct measurement of the strain, both tension as well as compression
  • The displacement can be derived from the distance between the anchoring points
