Description
- The vibrating wire lining stress gauge is embedded in tunnel linings to measure the effective strain within concrete, allowing the assessment of structural stability.
- This product uses a rosette block to mount strain gauges in 2–4 directions, enabling easy measurement of strain magnitude, distribution, and trend.
- It can also be used for long-term monitoring of structures such as dams, bridges, and subways by comparing stress-free and loaded conditions using a case designed for stress-free strain gauges.
