Embedded strain gauge

1. Embedded strain gauge product overview

Embedded strain gauge adopts vibrating string elastic beam structure, which is suitable for long-term embedding in concrete structure and bedrock to monitor its stress and strain.The vibrating wire strain gauge is an embedded strain gauge.It can be buried in beams, piles, pile foundations, supports, hydraulic buildings, 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 simultaneously measure the temperature of the layout point for indoor use.Temperature correction of buried strain gauges.

2.Embedded strain gauge application scenarios

Bridges, tunnels, rail transit, water conservancy, buildings

3.Embedded strain gauge product features
