Plumbline

Geotechnical monitoring involves using many geotechnical sensors, each designed for specific function and usage in all types of conditions. These monitoring sensors are curated to be extremely reliable, durable, and weather-proof in many conditions.

PLUMBLINE

Plumbline with Optical Prism Readout

The normal and inverted plumb lines are simple and reliable systems that are widely used in civil engineering projects where highly accurate long-base rotation/tilt/relative displacement measurements are needed, like in high rise buildings, concrete and masonry dams, nuclear plants, etc. Plumb line is mainly used in concrete and masonry dams for measurement and monitoring of relative displacement between:

  • Dam top and the base
  • Base and the foundation rock

Portable optical readout system

The system employs two travelling telescopes (one each for X and Y axes) for measurement of displacement. The travelling telescopes are mounted at right angles to each other. This obviates the necessity of moving and realigning the telescope, plumb line and reference plumb every time a reading has to be taken in the X and Y axes. Two travelling telescopes not only cut short the observation time but also minimize any chance of error.

To facilitate observation from the same direction, one of the telescopes is provided with a right angle prism before the objective lens.

PLUMBLINE

Plumbline with Automatic Readout

The normal and inverted plumb lines are simple and reliable systems that are widely used in civil engineering projects where highly accurate long-base rotation/tilt/relative displacement measurements are needed, like in high rise buildings, concrete and masonry dams, nuclear plants, etc. Plumb line is mainly used in concrete and masonry dams for measurement and monitoring of relative displacement between:

  • Dam top and the base
  • Base and the foundation rock

The advanced automatic readout unit with remote real time monitoring facility, comprises of two contactless inductive sensors that give position of the pendulum wire in two directions. It is very precise system providing an accuracy of 0.01 mm. Pendulums already in situ can be measured by the readout unit without additional modification. It only requires a target to be added to the pendulum wire for the device to be effective.

The readout unit is equipped with a specific temperature gage that provides proper reference when temperature compensation is required. An additional transducer for automatic compensation of the wire rotation is mounted on one of the two axes
