Strain Gauges

Strain gauge bars are essential tools for monitoring stress and deformation states in load-bearing structures and support systems. They are commonly used to assess load variations on tunnel supports during excavation, as well as to control temporary or permanent retaining structures.

The strain sensor, positioned in the central part of the bar following a specific configuration, is designed to compensate for thermal variations and mechanical flexure, ensuring highly accurate and reliable measurements.

The bar operates in both tension and compression, and the sensitive zone is protected with a special resin coating that makes it impact-resistant and waterproof, suitable for harsh environmental conditions.

Fully waterproof, the strain gauge bar can be installed on the surface of stressed structures or Embedded in concrete casts for internal stress measurement
