For the monitoring of dams, pendulums and tense wire collimation have become increasingly popular. These control systems allow simple and immediate measurements to be taken, meaning that the collection of this data can also be entrusted to technically unqualified personnel.
The need for coordinometers for non-qualified users has prompted our research, development and production of the manual EGS coordinometer which perfectly meets this purpose.
The instrument is made in two versions for different uses:
– EGS – 2C for the measurement of pendulum wires
– EGS – FT for measurement with horizontal tense wire
The above models differ substantially in optical and mechanical components, they use the same electronics, appropriately configured.
The EGS-2C is portable, manually operated, and able to provide, with a single positioning, the measurement of the two planimetric coordinates of the wire’s position with respect to a fixed point in the structure to be monitored.
The EGS-FT instrument is portable, manually operated, and able to provide the position of the horizontally tense wire with respect to a fixed point in the structure to be monitored.
Taking measurements is simple and objective because the operator is not required to evaluate anything, simply to correctly use the instrument.
The EGS-2C coordinatometer is an excellent instrument for the measurement of the wire movements of a pendulum, both straight or reverse.
Generally used where the use of pendulums is possible, in particular major applications are:
- Historical buildings and monuments
- Civil construction
- Vertical supporting works
Features and Benefits
- Great accuracy
- Easy to use
- Objectivity of measurement
- Reduction of errors linked to the execution of taking measurements
- High long-term repeatability
- Maximum reliability
- Long Life of the system lifetime
- Minimal wear and tear
- Low maintenance required
- Integrated functions of self-diagnosis and testing
The read control unit is composed of a lower support base, beneath which are located three spherical centering feet for positioning the instrument on its base. On the upper part is a cart which carries the two optoelectronic pairs (arranged in an orthogonal and a 45 ° to the axis of advancement of the cart).
The operating knob is fixed to the rear of the cart, this allows the movement of the cart and the execution of measurement. The FT version is equipped with a single optoelectronics pair arranged vertically to the instrument.
The cart is operated by turning the rear knob to move an endless screw coupled to a special device for the reduction of mechanical backlash between the screw and the cart itself. The cart is also guided by a lateral axis along which it slides with Bushing type ball bearings.
The support of the advancement screw is constructed radially on bushings and axially with thrust bearings.
