Embedded strain gauge

1. Embedded strain gauge product overview

Embedded strain gauge is mainly used to measure the internal strain of concrete structures and is suitable for all kinds of concrete structures.The vibrating wire strain gauge is an embedded strain gauge. It can be buried in beams, piles, supports, hydraulic structures, linings, piers and bedrock of various concrete structures for a long time to monitor their stress and strain. The built-in analog temperature sensor can synchronously measure the temperature of the installation point for temperature correction of the embedded strain gauge.

2. Application scenarios of Embedded strain gauge

Bridges, tunnels, rail transit, water conservancy, buildings

3. Features of Embedded strain gauge

1. Adopt imported steel string design, with advantages of high sensitivity and precision, good linearity and stability
