Strain and Displacement Gauging
TISEC Inc. specializes in strain and displacement analysis for a wide variety of structures. Common structures that undergo strain and/or displacement monitoring include:
- Bridges
- Pavement layers
- Locomotive rolling stock
- Load bearing high-rise components
Strain and displacement gauging provides valuable data
Strain and displacement gauging provides valuable data on structure deformation in 2D or 3D due to loading. Gauging monitoring may extend to cover vibration, rotation, acceleration, and temperature. A multi-channel data acquisition system is used to collect the data and compute the principal values of strain and displacement. Principal stress can then be calculated from measured strain values. The picture shows Strain Rosettes used for stress analysis of a locomotive wheel rim during impact loading.
- Dynamic laboratory testing
- Static laboratory testing
- Failure testing
- Short-term field monitoring
- Long-term field monitoring
Wireless Monitoring
Strain gauges and other measurement sensors are linked wirelessly to a base station installed inside an enclosure. The base station contains a micro PC, wireless receiver station and cell modem gateway. The wireless communication protocol allows the sensors to be synchronized together and record the data at the same time sending the data to the base station.
This network provides a full control on the entire monitoring system from a master control room starting from collecting data and going through data storage and transferring then data analysis and reporting.
Our American Society for Nondestructive Testing (ASNT) certified inspectors have complementary training in fall protection, rope access, highway safety, railway safety, first aide, and confined space safety. We have a proven track record for high quality nondestructive testing services and safety.
