Dynamic Monitoring Stations

Imetrum's Dynamic Monitoring Station (DMS) can be used to monitor the dynamic movement of civil and geotechnical structures.The DMS system is able to measure position (displacement, distance), strain (expansion, contraction, crack opening) and rotation (twist, tilt and bending) of a structure. One of the key advantages of using DMS is that there is no need to access a structure directly to measure it. This eliminates many project delays related to access such as arranging possessions or traffic management, and also delivers safer working practices by keeping staff and vehicles apart as well as eliminating the need to work at height or over water.


The benefits

The DMS is a multi-point dynamic monitoring system that can take measurements similar to those generated by a strain guage, LVDT, tilt meter or Robotic/Automated Total Station. The system is easily scalable, and has been used for testing individual structures from less than 1 m to over 1 km long.

Imetrum's DMS has been independently benchmarked by many companies, including the UK's National Physical Laboratory. Measurement capability is often described as being "the benefits of a non-contact device, with the resolution of a contacting one". It can be supplied with calibration certificates from an independent test house if required.
