What is the application of analytical laser rangefinder in the construction industry?
Building measurement is the first and most important process of building construction.With the development of society, more and more high-rise buildings in our country, in the construction and the decoration of the floor in the future, the measurement of the height of the building, the space between two points, the area, the use of materials, structural deviation, etc., are related to the safety of the whole floor building.At present, the most commonly used measurement things include all kinds of rangefinders, laser rangefinders, telescopic rangefinders, etc., using these measurement things, can reduce the measurement time together, make measurement more accurate.The company's laser rangefinder has been successfully used in the construction industry.
Laser rangefinder double injection of non-slip soft adhesive planning, so that users have a comfortable sense of holding hands.In addition, the compact and simple appearance of the laser rangefinder and the "measurement and targeting integration" plan make the laser and the line of sight in the same line, greatly reducing the error between the laser emission point and the line of sight, making the measurement results more accurate.
Laser rangefinder small volume, light weight, easy to carry, measuring range of 0.05-50 meters, the error is only plus or minus 1.5 mm, easy measurement of area, volume, the operation principle is to use the laser to the policy of accurate measurement of the interval of the instrument.When the laser rangefinder works, it shoots a very fine laser beam to the target. The laser beam reflected by the target is received by the photoelectric element.
Its large LCD backlit display allows you to easily read measurement data together with your eye alignment.In addition, the use of simple safety, only need to operate alone and do not need to use other things (such as ladders, etc.) can be completed all measurement work, even inaccessible parts can be easily handled, thus avoiding injury accidents at the maximum level.
Laser rangefinder can be applied to all kinds of construction projects, such as the construction industry various intervals, area, volume measurement, positioning formwork orientation, calculation of concrete casting quantity, etc.Decoration company USES its fast and accurate finish light steel keel positioning and device;In the telecommunication industry, this laser rangefinder can be used to finish all kinds of measurement work needed for cable and wire installation.When the electromechanical device, the laser rangefinder can ensure the length of pipe and the length of the device are the same, and ensure that the materials are in place and not wasted.
The principle of telescopic rangefinder and its key points of selection
Telescopic rangefinders usually use the pulse method to measure distance.The pulse method works as follows: the laser emitted by the rangefinder is reflected off the object to be measured, and is then received by the rangefinder, which simultaneously records the time of the laser round trip.Half the speed of light times the round trip time is the distance between the rangefinder and the object being measured.The accuracy of the pulse method used to measure the distance is usually about +/- 1 m.In addition, such rangefinders typically measure dead zones of about 15 meters.
Points of selection
1. The basic parameter of a telescopic rangefinder is to measure distance.First, you should choose a telescopic rangefinder that needs to measure distance.
2. Measurement accuracy. The nominal measurement accuracy of all manufacturers is +/- 1 meter, which is only theoretical data.The measurement accuracy depends on the target environment, telescope rangefinder lens, infrared laser emitter quality and data processor accuracy.
