Product Introduction
The embedded strain gauge system is a high-precision measuring instrument used to measure internal strain changes in concrete structures. It is a string-type sensor suitable for long-term and stable monitoring in geotechnical, hydraulic structure, and structural safety monitoring projects. It is primarily applied for monitoring internal concrete strain in projects such as dams, bridges, foundations, and slopes.

Working Principle
Based on the vibrating wire principle, the sensor consists of a force-bearing elastic housing, a steel wire, excitation components, and a receiving coil. The frequency of the vibrating wire changes relative to the tension magnitude. Once determined, variation in vibration frequency characterizes the strain magnitude of the measured structure. The YTVA01A features a grounded double-protective-sheath and shielded polyurethane design for resistance to mechanical wear and interference.

Application Fields
The embedded strain gauge is extensively used for strain monitoring in concrete structures across projects such as reservoirs, dams, high-rise buildings, foundations, tunnels, bridges, and slopes.
