Plumb Line Systems

This system monitors horizontal displacement and deformation by measuring a plumb line (perpendicular line used as a reference) installed inside the dam body, and is crucial for managing safety. We offer a normal plumb line system that measures dam body deflection based on the relative displacement between the dam top and bottom, and a reverse plumb line system that measures the horizontal displacement of the dam against an unmoved rock mass based on the relative displacement of the dam bottom and unmoved rock mass. A deflection detection system (automatic measuring instrument) measures and outputs a range from 0 to 100 mm (±50 mm) in the X and Y directions in real time. Also, a portable coordinator (manual sensor) calibrates and checks the automatic measuring instrument and measure X and Y directions, simultaneously. *Manufactured by TAMAYA TECHNICS INC.
