How to choose a laser self-leveling level

Even the simplest repair will not do without the use of a building level. Previously, in the old fashioned way, all sorts of hand-made plumbs, strained threads, and bottles of water were used. Now the need for such applied art has disappeared altogether, because laser levels appeared on the construction market. These are the unique devices allowing to carry out any construction works with high precision. How to choose a laser self-leveling level? What characteristics need to pay attention in the first place? Need to understand.

Laser level. Design features and work

In order to understand how to choose a laser self-leveling level, you need to understand its structure and principle of operation. A standard laser device consists of several systems operating in combination. These include:

  • emitters;
  • focus adjustment system;
  • Power Supply;
  • leveling and leveling mechanism;
  • Control block.

Laser-level light sources are fairly powerful LEDs. They generate monochromatic light. Usually in professional and amateur devices, the beams come in a red or green hue, which can be seen quite clearly at a distance of more than 40 meters. Installed LEDs do not heat up, use a minimum of electrical energy and do not shine worse over time.

Helpful advice! The green beam is brighter, it can be better seen at work during the day, especially at large distances without using a special receiver.

Each laser level is equipped with a special lens system capable of focusing the resulting beam at one point. High-quality optics guarantee high accuracy during operation and clear visibility. Some devices are equipped with special prisms that are able to scatter the beam and turn it into lines. Such equipment is more convenient to use.

In such mechanisms the rule of the pendulum is used. If the equipment is set strictly horizontally, the built-in plumb motionless. With a small deviation, the head of the pendulum deviates and, when interacting with a magnetic field, produces a current, under the influence of which the system corrects the position of the level. The most accurate systems are able to respond to deviations in tenths or hundredths of a degree per meter. At 10 meters, the deviation cannot exceed 1 mm. Professional instruments with gyroscopes and servo drives respond much faster to deflection and provide maximum accuracy.

The laser level is battery powered. For these purposes, manufacturers use mostly nickel-cadmium variants, which can be recharged from the network without any problems. High-quality battery ensures uninterrupted operation of the device for 7-10 hours with continuous operation. Management on all models is very simple and is done with a few buttons.

To determine how to choose a laser self-leveling level, you need to know about all the existing varieties. Similar measuring devices come in several forms. Depending on the measurement accuracy, additional functions can be identified:

  • laser range finders;
  • static line builders;
  • rotary plotters.

The laser rangefinder allows you to measure the distance to the object with high accuracy, calculating the time it takes for the beam to reach the desired point. Such an instrument is often supplied with professional equipment.

Static builders – higher level devices. They allow you to get intersecting horizontal and vertical at an angle of 90 ?. Can project 2-8 lines at one time. Such models already use prism optical system.

Rotational levels. Laser level 360 degree self-leveling

Rotary builders – the most powerful, high-quality and multifunctional devices. They are equipped with a head capable of rotating and creating an image of the luminous plane horizontally and vertically. Such models are often completed with remote controls.

Due to the rotation of the light beam, the device forms a plane. This laser level is easy to check any surface and identify defects. An additional function in it is the ability to create a beam directed strictly to the zenith. The range of the beam manufacturers say about 50-70 m, but when using a special receiver, this figure can be increased to 300-400 m. The head of the level can rotate at a speed of 10-600 rpm. The higher the speed, the better and clearer the image.

The laser self-leveling level of 360 degrees is quite a powerful and easy-to-use device. Its head can rotate in almost any direction, creating both horizontal planes and vertical ones. Self-leveling indicator in it is small up to 4 degrees. There are samples with a self-leveling rate of up to 60 ?, but they are very expensive and their acquisition may simply be unprofitable.

There are many indicators that determine the exact and uninterrupted operation of the laser level. We list the main ones:

  • error;
  • range of work;
  • type of laser;
  • power class;
  • battery capacity;
  • self-leveling function;
  • protection;
  • equipment.

Accuracy is one of the important characteristics of any level. The result of work directly depends on this indicator. Its values ​​should not exceed 1-3 mm per 10 m. Professional devices have an error of 0.5-1 mm. When working indoors, an error of 3 mm is almost imperceptible, such equipment is perfect for use at home.

Medium construction levels are equipped with 1 or 2 class lasers. These are low and medium power sources of light, but even they can adversely affect vision. Class 3 laser is used in professional devices.

Battery capacity is also an important indicator. Professional devices work without interruption for about 30 hours. For less powerful equipment, this figure is 10-12 hours. For home use suitable batteries with an average capacity, but with a high charging speed.

Helpful advice! The self-leveling function in the instrument must be able to turn off. This is convenient if the device needs to be placed at a certain angle.

Since the laser self-leveling levels of 360 degrees are often used in rather adverse conditions, their internal parts must be reliably protected. For high-quality models, special hermetic and shock-proof housings are used. Many samples for greater convenience are equipped with goggles, equipment case, tripod. The kit must also include a charger if the device is powered by a battery.

How to choose a laser self-leveling level

Knowing all the details of the device and the work of laser construction levels, you can choose a good option for use at home. Powerful and high-precision models can be left to professionals.
