Strain gauges

They provide precise microscopic diagnostics for fatigue detection and stress analysis in materials, ensuring high survivability and thermal compensation. They are widely used in bridges, viaducts, tunnels, industrial silos, piles, wind turbines, and dams.

Key variants include weldable industrial vibrating wire strain gauges, encapsulated sensors for direct embedding in concrete during pours, and rebar strainmeters ("Sister Bar") that are tied to reinforcement bars. They also include electrical resistance devices suitable for measuring rapid dynamic events and acoustic devices embedded in joints.

These strain gauges are integrated via cabling to multiplexers and dataloggers that send information to control platforms.
