◀◀ Key Selling Points ▶▶
Embedded Design
Directly installed in concrete or reinforced concrete structures (dams, bridges, tunnels) for long-term strain monitoring.
Multi-Model Versatility
BGT4200/4200HP: Ideal for foundations, piles, and tunnel linings; expandable to multi-directional strain gauges or stress-free sensors with accessories.
BGT4210: Optimized for mass concrete structures.
BGT4210RCC: Heavy-duty design for roller-compacted concrete (RCC) applications.
BGT4200X: Compact one-piece structure for simplified installation.
High Sensitivity
Detect micro-crack openings as small as 1μm when extended-gauge models are used in boreholes.
Integrated Temperature Compensation
Built-in temperature sensor ensures accurate strain measurements under thermal variations.
Customizable Configurations
Optional extended gauge lengths for specialized applications (e.g., crack monitoring).

◀◀ Application Scenarios ▶▶
Hydraulic Engineering
Monitor concrete strain in dam foundations and spillways to prevent structural fatigue.
Bridge & Tunnel Construction
Embed BGT4200HP in tunnel linings to assess load distribution and deformation risks.
Infrastructure Health Monitoring
Deploy BGT4210 in mass concrete pillars or bridge piers for long-term stability tracking.
RCC Projects
Use BGT4210RCC in roller-compacted concrete layers (e.g., roadbeds, embankments) to ensure compaction quality.
Micro-Crack Detection
Install extended-gauge BGT4200X in boreholes to monitor crack propagation (1μm sensitivity).
