The optical level, a type of Topographic level, has become an essential tool in construction processes. Its use is essential to carry out measurements of angle, height and distances in the open field, as well as within any structure or building.
The management of the optical level is very practical for preparing land suitable for construction, erecting retaining walls, creating tunnels, and even in the agricultural sector it is highly functional for laying water pipes and flattening the land for plowing.
Being an instrument of wide use in various fields of work, we have compiled the 10 most important things you should know to learn even more about this valuable tool.
1. Its use is regulatory
Optical levels are measuring devices made to accurately indicate horizontal levels, angles, heights, and distances; For this reason, its use is regulatory in all constructions that merit this tool to collect the necessary information in all phases of the project.
2. They offer high range and precision
Optical levels offer greater range through your lens. Its precision can vary between 7 and 150 mm per kilometer of leveling.
The minimum measurement range to use this tool is usually around 30 cm, while 35 or 36 mm diameter objectives provide an angle of view very similar to that of the human eye.
The magnification or magnification of each lens will also determine the accuracy of a measurement.
3. Some optical levels use units of measure in gon
Survey tools use gon or centesimal degree as the default unit. Each quadrant is assigned a 100 gon interval, which helps to recognize and calculate the angles.
For example, 90 degrees equals 100 gon, 180 degrees equals 200, and respectively 360 degrees equals 400 gon. By increasing the frequency of use of the instrument, you will be able to recognize calculations and conversions more easily.
4. Include various safety accessories
The optical levels are designed with a robust metal housing, ideal for transport and outdoor application.
Tool security is complemented by a compensator locking device, protective lens cap, and carrying case for easy portability. Most of the models sold include these accessories.
5. Choose the magnification of the objective according to the application
The magnification of the lens will depend on the space where we use the tool and the precision type required during measurement.
Objectives with a magnification between 18x and 28x are ideal for small and medium-scale works. In case of needing a measurement at a greater distance, we can opt for lenses with magnification between 28x and 32x.
Lenses with magnitudes from 30x to 34x are used to achieve maximum precision in tasks where it is necessary to obtain a measurement with greater accuracy.
6. Automatic optical levels are easier to use
This type of topographic level makes it possible to maintain the horizontality of the optical axis when the surface is uneven.
Today almost all models of this instrument include a compensator that allows automatic calibration.
The gravity or magnetic compensator that accompanies this tool generates an automatic and very precise leveling, avoiding errors produced by the placement of the instrument on the surface.
7. We must select a degree of protection
Each optical level model has a degree of protection. In DIN standards it is known as the IP Protection Code, composed of two digits that represent the protection of the equipment, and range from 0 to 6 regarding its protection against solid objects, and a category from 0 to 8 to define its protection against liquid objects.
Levels 5 of each range protect the tool against dust and water jets, so an optical level with a degree of protection IP-55, will not allow dust to affect its operation and can receive water splashes from any angle by a period no longer than 5 minutes.
8. We must take preventive measures
We must protect the device from moisture and continuous exposure to the sun. Sudden changes in temperature could also affect the instrument.
If the measuring tool has been exposed to a sudden change in temperature, it is advisable to wait a few minutes for the device to warm up, avoiding any precision errors during the measurement.
9. It is always up to us to verify accuracy
Before starting the work, we must verify the leveling accuracy with the indication of the apparatus, and thus ensure the precision of the instrument.
If the device suffered a blow or fall, we must again check the precision and condition of all the parts.
10. Optical levels should be repaired by professionals
Save the equipment instructions and review them for any failure of the tool. Optical levels should only be serviced by professionals. If you detect any type of failure or breakdown in any of the parts, their replacement must be made with an original spare part.
The optical levels they are tools of great importance in the construction area. Its application has expanded to various environments, but its handling in all areas requires skill and care during handling.
Knowing a little more about this tool allows us to prepare for practice, where we will put everything we have learned to bear.
