Video Gauge

Product Code:

The Video Gauge provides a revolutionary way of making real-time in situ high resolution measurements without the need to access a structure. Imetrum are able to monitor movement to better than 0.1mm of a wide range of structures, under loading, without the need for possessions, traffic management, working from height or over water.

Description

The Video Gauge provides a revolutionary way of making real-time in situ high resolution measurements without the need to access a structure. Imetrum are able to monitor movement to better than 0.1mm of a wide range of structures, under loading, without the need for possessions, traffic management, working from height or over water.

The Imetrum Video Gauge has the ability to generate displacement values to a suitably high resolution without the need to access the track to install any physical targets. Meaning you can monitor deflection under train loading at normal line speed (120mph). This leads to safer working practices, and substantial time and cost savings when compared with traditional instrumentation. The Imetrum Video Gauge is ideally suited to monitor both Track and Rail bridge structures.

  • Multi-point dynamic monitoring
  • Measure strain, displacement and rotation
  • Real time operation (up to 400Hz)
  • Rugged weatherproof casingresolution achievable

DYNAMIC MEASUREMENT UNDER LOAD

Because of the heavy, periodic loading caused by trains, the dynamic response of a Rail Bridge is often the most useful means of assessing its structural health. Whilst this is done anecdotally by drivers regularly as they report changes in ride comfort, there are times when a more localised and specific, or more accurate assessment is required.

Up to 4 cameras can be plugged in to a single controller, meaning that multiple areas of a structure can be measured simultaneously, or measurements taken at different scales. Over 200 measurement points can be specified on a single image, leading to a detailed understanding of structural behaviour.
