VM-16 with active illuminated target board. Range up to 130 m, depends on diameter of pipe and dimensions of target. The video measurement system VM-16 was specially developed for controlling pilot pipes. It can also be used for a wide variety of other tasks and has proven itself worldwide in rugged construction site conditions. The functional principle is as simple as it is ingenious a pilot pipe is pressed through the earth by the ground displacement method. The control adjustment is carried out quite simply by the inclined face of the control head. The inclination is related to the control axis of the target board. The arrangement of the target board places the all-important control axis in the centre. The target board is observed with a theodolite. A CCD camera transmits the picture to the monitor. Deviations from the target axis can be seen immediately and are corrected by turning the pilot pipe. The rotation is stopped as soon as the control axis is on the centre point of the telescope reticule. The height and direction are then corrected automatically as driving proceeds. The target axis is reached when the centre of the target board coincides with the centre of the telescope reticule.
In addition to the VM-15, this model provides a remotely controlled motor-focus of the theodolite’s focus and a digital control of the illuminated target board. These functions are controlled via the monitor MF-03.
Note: Monitor MF-03 needed!
Remote controlled focus
Together with the monitor MF-03 the focus of the theodolite can be remotely controlled.
Image scale: at 100 m target distance 1 : 0.5 to 1 : 2, Standard devation: ± 10 mm/100 m
The first solution for quick and accurate line transmission and monitoring. Use the good method of line orientation from bottom to top to your advantage.
Adjustable illuminated target board
The illumination of the target board can be adjusted according to the environmental conditions at the monitor, which is e separately available .
Specific monitors and LED-targets guarantee a perfect harmonized system.
