Embedded strain gauge

1、 Product Overview

This vibrating wire strain gauge is a type ofEmbedded strain gaugeIt can be buried in various concrete structures such as beams, piles, supports, hydraulic structures, linings, piers, and bedrock to monitor their stress and strain. The built-in analog temperature sensor can synchronously measure the temperature at the installation point and be used for temperature correction of embedded strain gauges.

2、 Application scenarios

Bridges, tunnels, rail transit, water conservancy, buildings
