An Automatic pendulum co-ordinator is used to record the dam deflection and base movement automatically. This non contact type auotmatic remote monitoring type pendulum co-ordinator is designed to provide monitoring teams a simple and effective means to electronically "log" the tilt or "rotation" of the structure.

Soil Instruments Automatic XY Plumbline Coordinator,measures the Dam deflection automatically, and this data can be remotedly monitored through a Data logger form the Dam top contro/Observation room.

Also known as "GEODETIC TARGET/ SURVEY MARKERS". These targets are extensively used for the measurement of deformation during (a) Tunneling (2) During sub way construction, and also for monitoring displacement/deformation in 3-directions of a Bridge/ Dam/Slope, and a structural structure on the top of the "Tunnel alignment", and for the structural/structures in Zone-of-Influence.

Digital Tape Extensometer is used for measuring and monitoring of surface, lateral ovements, radial movements & convergence between pair of reference studs. The Digital Tape Extensometer which is (Portable), measures the displacement between pair of reference eye bolts, grouted in to shallow drill holes in the structure OR excavation.

Electrolevel Beam Sensors are meant for the differential displacement of structure measurement ofdetect differential movement and rotation in structures. These Beam sensors are installed on a 3 m beam, and severa beams are connected is series, and terminated in to a Data Logger (Data acquisition system) for unattneded/remote monitoring, this also provides a deflection profile of the structure under observation/monitoring.

Hanging / Inverted Pendulum are used in Concret/Masonary/Gravity Dams for monitoring the deflection of the Dam. The Hanging pendulum uses a wire and a T-Square OR verniar microscope. Theupper end of the wire is anchored to the structure under observation. A weight is suspended fromthe lower end is free to move in an oil tank, the oil is meant for acting as an damping agent, to damp the oscillations of the wire.
