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.
MICHAEL Owen has also been busy, developing this PRC200 watch with Tissot, which combines a chronograph (designed as a number 10, MO's shirt number), a tachymeter
and date function on a white face, with the option of three metal bracelets or two leather straps.
The 18K OMEGA Sedna(tm) gold bezel is enhanced by a matt black ceramic ring with a tachymeter
scale, a defining element of the Speedmaster collection.
A computer was connected to a motorized tachymeter
and measuring device prototype.
Three hand-applied semi-circular counters on a black dial with spiral effect and "Calibre S" and "Laptimer Retrograde" inscriptions; polished 43mm stainless-steel case; fixed black aluminum bezel with tachymeter
scale; red second hand; luminescent markers on the red-tipped counter hands and the indexes; polished pushbutton crown with black varnish; hand-applied TAG Heuer logo; water resistant to 100 metres and a black strap with red stitch lining.
The series also includes automatic mechanical chronographs with a date window at six o'clock and a tachymeter
on the dial.
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
The Big Ingenieur Chronograph in platinum, rose gold and stainless steel also brings together everything that is good, innovative and exceptionally hard-wearing: the IWC manufactured 89360 calibre chronograph movement with a double-pawl winding system, flyback function and analogue display of long stop times, design of the movement for robustness and a larger case with a tachymeter
It can also be used to measure the actual speed on the tachymeter
scale over a reference distance of 1,000 metres, forexample.
Then on October 3, 2002, the total station angle and distance measurements with Leica TCA 2003 tachymeter
in a 10 measurement series were realized.
