Plumbline With Automatic Readout

Model EPR-01S Overview

Encardio-rite 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

Model EPR-01S is an 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.

Model EPR-01S 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
