SK-DSM Vibrating Wire Soil Extensometer
Short Description:
Overview
The Enviko SK-DSM vibrating wire soil extensometer has flanges at both ends and is embedded in soil to measure displacement in highway embankment fills and dams. It is a robust, accurate and easily installed instrument that can measure displacement in any direction at a given location in the soil mass. Units can be installed singly or in series. A built-in temperature sensor records the temperature at the installation point, and a smart ID chip can be fitted on request.
Key Features
- Flanged ends anchor the instrument in the fill
- Measures displacement in any direction within the soil mass
- Install singly or in series for a displacement profile
- Waterproof to 2 MPa (up to 3 MPa on custom versions)
- Robust and easy to install
- Built-in temperature sensor; optional smart ID chip
Applications
- Highway embankment fills
- Earth and earth-rock dams
- Other compacted fill structures
