Embedded strain gauge

1.Embedded strain gauge product overview

Embedded strain gauge can be directly embedded in concrete and is usually used for strain measurement of foundations, piles, bridges, dams, and tunnel linings.This vibrating strain gauge is an embedded strain gauge.It can be buried in beams, piles, pile foundations, support, hydraulic buildings, linings, piers and bedrocks of various concrete structures for a long time to monitor their stress and strain.The built-in simulated temperature sensor can measure the temperature of the layout point simultaneously and is used for temperature correction of the embedded strain gauge.

2.Embedded strain gauge application scenarios

Bridges, tunnels, rail transit, water conservancy, buildings

3.Embedded strain gauge product features

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