Optical plummet
Introduction
The theodolite is a mechanical-optical measuring instrument that is used to obtain vertical and horizontal angles, in most cases, an area in which it has high precision. With other auxiliary tools you can measure distances and differences in level.
It is portable and manual; It is made for topographical and engineering purposes, especially for triangulations. With the help of a scope[1] and through tachymetry, you can measure distances. A more modern and sophisticated equipment is the electronic theodolite, and another more sophisticated instrument is another type of theodolite better known as a total station.[2].
Basically, the current theodolite is a telescope mounted on a tripod and with two graduated circles, one vertical and one horizontal, with which the angles are measured with the help of lenses.
The theodolite is also a very easy tool to transport. That is why it is a tool that has many guarantees and advantages in its use. It is its precision in the field that makes it important and necessary for construction.
Classification
Contenido
Los teodolitos se clasifican en teodolitos repetidores, reiteradores, brújula y electrónicos.
Repeater theodolites
These have been manufactured for the accumulation of successive measurements of the same horizontal angle in the limb "Limbo (instrument)"), thus being able to divide the accumulated angle and the number of measurements seen.
Reiterating theodolites
Also called directional, reiterating theodolites have the particularity of having a fixed limb "Limbo (instrument)") and only the alidade can move.
Theodolite-compass
As its name says, it has a built-in compass with special features. This has a magnetic compass with the same direction to the horizontal circle on the diameter 0 to 180 degrees of great precision.
