SK-MD Vibrating Wire Multi-Directional Strain Gauge Rosette
Short Description:
Overview
The Enviko SK-MD strain gauge rosette groups 3, 5 or 9 vibrating wire strain gauges on one mounting bracket to measure strain in several directions at the same point inside concrete. Each gauge has an integrated strain body and a built-in temperature sensor. A smart chip can be added on request.
Key Features
- 3, 5 or 9-direction configurations on YBZZ mounting brackets
- Integrated strain body for true readings
- Anti-torsion design
- Easy installation
- Built-in temperature sensor in each gauge; optional smart chip
- Four gauge lengths: 100, 150, 200 and 250 mm
Applications
- Concrete dams and masonry dams
- Hydropower plant powerhouses
- Bridges and tunnel linings
- Concrete foundations and bedrock
- Any location where the full stress state of concrete must be determined
