This stand is composed of the following elements: a static frequency converter that supplies a three-phase asynchronous motor, a digital tachymeter
for rpm measurement, a central unit and monitor for control and monitoring, and a single-phase synchronous generator for loading the three-phase asynchronous motor (Livinti, 2007).
The experimental works involved taking pictures of plate targets for the set values of the zenith angle and horizontal direction of the tachymeter
telescope and shifts of the micrometric table in the horizontal plane.
For measurements are used two electronic tachymeters
It can also be used to measure the actual speed on the tachymeter
scale over a reference distance of 1,000 metres, forexample.
Disc 1 is driven by electromotor 5 where the rotation velocity is calibrated by the transistor converter 6 for the frequency regulation "Mitsubishi" (type A500); number of rotations is measured by nonconcact digital tachymeter
"Sanwa" (type SE-100).
The landslide monitoring systems consist usually on in-situ borehole measurements (inclinometers and piezometers) and on the surface, it consist of a set of geodetic benchmarks measured with GPS and tachymeter
Made of brushed titanium, the case is surmounted by the bezel, also with brushed finish but with edges in polished titanium, which carries the engraved numbers of the tachymeter
At first glance, this watch is distinguished by its expert blend of colors and materials: black, steel and a dynamic dash of orange picked up on the sweep seconds hand, the tachymeter
numerals and the stitching sailcloth strap.
Then on October 3, 2002, the total station angle and distance measurements with Leica TCA 2003 tachymeter
in a 10 measurement series were realized.
