Automatic level

What is an automatic level? Also called an auto level, an automatic level is a professional leveling tool that is often used by land surveyors, builders, contractors, and engineers. And it's best known for its ability to provide consistent level accuracy more quickly than many other leveling instruments.

How do automatic levels work?

Auto levels use a standard sighting telescope, but the light entering the objective lens passes through a mechanical compensator system before reaching the user's eye. Conpensator's often consist of a prism suspended with very fine wires so that plumb is established and light passing through the prism is set to plumb.

Why is it called an automatic level?

An automatic level, self-levelling level, or builder's auto level includes an internal compensator mechanism (a swinging prism) that, when set close to level, automatically removes any remaining variation.

What is the advantage of using automatic level?

Advantages of Auto Level

The auto level has an internal compensator mechanism which automatically adjusts the line of sight. The measurement accuracy of the auto level is higher. Auto level results are very reliable. Ease of use of auto level saves time and money.

How accurate is automatic level?

An automatic level with 18X magnification can give readings accu- rate to 1⁄16 inch in 100 feet. A conven- tional level with the same magnifica- tion has an accuracy of about 1⁄4 inch in 100 feet. Also, to ensure accurate readings with a conventional level, the operator must check it frequently for proper adjustment.

What is automatic leveling control?

Automatic Level Control (ALC) is a technology that automatically controls output power to the speaker. ALC prevents loudspeaker overload and optimizes dynamic range.

What are the 5 parts of automatic level?

The basic setup of an automatic level consists of the telescope, the circular level, three leveling screws, and a compensator. However, there are plenty more parts that play a key role in the success of the automatic level. Telescope - holds lenses that magnify objects in the sight.

What is the difference between dumpy level and autolevel?

Compared to an automatic level, a dumpy level is easier to manipulate but requires more precision from the surveyor. Surveyors will not need to make as many adjustments to a dumpy level as they would to an automatic level, as dumpy levels can retain adjustments for a longer period of time.

What is the difference between auto level and theodolite?

Theodolites can be used to measure elevations, but auto levels will do this more accurately over long distances. An auto level is a professional-grade leveling tool used by builders and surveyors who depend on accurate leveling at every turn.

How many types of auto levels are there?

There are various types of levels such as dumpy level, Y level, cushing's level, tilting level, cooke's reversible level and automatic level instruments for leveling in surveying.

How is automatic level used to measure distance?

In the auto-level machine, the difference in the stadia hair reading is set at the 1: 100 ratio. i.e. if the reading difference is 1cm, that represents 1m. over the ground. So, to get the measurement over the ground, you have to multiply the difference in the stadia hair readings by 100.

What are the two advantages of levelling?

Following are the advantages of levelling: Levelling helps to prevent soil erosion caused by wind or air. It helps in sowing the seeds uniformly, and thus helps the plants to grow uniformly too. It helps in proper irrigation by allowing the water to get distributed uniformly throughout the soil.

What is the history of automatic level?

Invented in the early 1700's, Dumpy Level was considered standard, until the Transit Level was invented in the 1830's. The level has further evolved into an Automatic Level. This automatic level is an optical instrument leveraged in surveying and building to transfer, measure, and set horizontal levels.

Is auto level and tilting level same?

2.3 The Automatic Level

As the automatic level does not have a telescope bubble there is no need for the telescope to be capable of tilting, therefore, there is no tilting screw either. Setting up and approximate leveling is done with the circular bubble in the same way as for a tilting level.

What is automatic optical level?

Automatic Levels

Professional automatic optical levels (also known as dumpy levels) are built for the construction site and general survey tasks. They are quickly set up, precise and will top every comparison of price to performance ratio.
