General Description
Our Smart Electro-Magnetic sensor is designed specifically to monitor real-time stress in bridge cables. The scope of application includes suspension bridges, cable stayed bridges, dome structures, concrete structures, and geo structures such as tie-rod and ground anchorage.
Features
- No direct contact with the structural member
- High durability for long term monitoring
- Stress measured directly rather than by inference from strain measurements
- Readings not affected or degraded by cable sheath
- Early warning system of impending deterioration
Technical Description
The Smart EM sensor system consists of 3 components:
1. Sensor
2. Power unit
3. Optional internet server
There are two sensor types:
- Pre-fabricated sensor for new structures. These are hollow cylinders that may be slipped over structural members during construction and prior to tie-off
- Site-fabricated sensors for existing structures. These are attached to the structural member in-situ by over-winding two semi-cylindrical bobbins
