TRANSIT LEVEL: 5 Best Transit Levels In 2022

transit level

Plane surveying (finding the location of structures, boundaries, and topographical features as though they were on a level surface) has a long history, dating back to the Egyptians.
The hammer is to nailing what the transit level is to plane surveying. It’s tripod-mounted optical equipment (basically a telescope) with a built-in spirit level. Read on to learn how the laser transit level works and our top options of transit levels in the market.

What is a Transit Level?

A transit level is a high-precision tool. It’s calibrated to show true horizontal as well as the angle of inclination in degrees, minutes, and seconds. A transit level is a varied and flexible tool capable of many jobs in the hands of an expert, yet some of its most fundamental applications are simple to master. As a result, anyone planning to construct a new construction will find this tool quite useful.

How Does It Work?

The transit level functions similarly to the builder’s level. To begin, you’ll need to assemble a tripod on which to put the transit level. You’ll need to adjust the leveling feet on the transit level once it’s securely secured to the tripod until the built-in level indicator reads that it’s level at every point in 360° rotation. So far, there’s no discernible difference between how a transit level works and how a builder’s level works.

However, once you’ve set up and changed the level, you’ll notice a difference. It can now be adjusted both vertically and horizontally, whereas the builder’s level can only be adjusted horizontally. You can use it to measure vertical angles while keeping the builder’s level’s elevation measuring capabilities by raising and lowering the front of the telescope.

A Transit Level’s Components

A transit level’s basic configuration includes the transit level itself, a tripod base, a tape measure, and a calibrated rod. The transit level itself is made up of several components:

How Do I Read a Transit Level?

  • Identify the eyepiece. The crosshairs can be brought into focus by turning this.
  • The leveling vial is located above the level’s scope.
  • The focusing knob is located at the end of the scope.
  • The horizontal graduated circle is a degree-marked circular guide used to read horizontal angles.
  • Just above the horizontal graded circle is the horizontal tangent knob, which is used to adjust left and right.
  • The vertical tangent knob is on the right side of the scope, on the near side, and is used to adjust up and down.
  • The vertical direction is locked in place by the vertical lock knob, which is just past.
  • Just below the horizontal graduated circle are the leveling screws. To keep the device level, these can be changed.
  • A detachable sunshade is available on some levels to shield sunlight from the lens.

Setting Up a Transit Level

  • Take the level out of its carrying case.
  • Place the level on the tripod head immediately.
  • The transit level should be threaded or bolted to the tripod base.
  • Place the protective lens covers in the carrying case after removing them.
  • Place the telescope’s sunshade on top of it.
  • Your transit level has been installed.

What is the Best Way to Focus a Transit Level?

The next step is to focus the transit level after ensuring that your instrument is level at all leveling sites.

  • The initial step in this procedure is to point your telescope at a specific target. The object should appear hazy, but rotating the eyepiece left or right should clear it up.
  • Point the telescope directly at the target after focusing the eyepiece. Use the focusing knob to make the given object appear sharp while maintaining the crosshairs in focus. A level grade line, also known as a reference line, is a sightline determined by the use of a telescope. It’s made at the horizontal crosshair, and it takes two people to make.

Drawing a Line of Reference

  • An additional worker keeps a graduated staff or tape measure vertical at the place under measurement while the operator looks through the telescope’s eyepiece.
  • During site surveys and building construction, the device and crew are employed to collect or transfer elevations.
  • The measurement begins with a known height benchmark or an arbitrary point with an assumed height.

Builder’s Level vs. Transit Level

Builder’s levels are extremely similar to transit levels. When a transit level’s telescope is fixed into place, it functions almost identically to a builder’s level. Between a transit level and a builder’s level, there is one major distinction. When not held in place, a transit level can only tilt vertically and has a very limited range of motion. The builder’s level, on the other hand, can move horizontally in a complete circle.

With their vertical moving mechanism, transit levels are excellent tools for measuring vertical angles. For establishing straight lines and turning angles, transit levels are preferable over other leveling equipment.

Transit Level FAQs

How accurate are transit levels?

With an accuracy of 0.0625 per 250 feet, this automatic transit level is one of the most precise optical instruments in its price range. Though we used the instrument to calculate horizontal angles and check elevations, it is also often used for other purposes.

How do you use a pool transit level?

Firmly press the legs into the soil. Carefully place the transit on the mounting plate. Turn the locking screw on the underside until it is snug. By adjusting the sliding legs or leveling screws until the bubble is exactly positioned, level the mounting plate to the center of the vial bubble.

Who invented the transit level?

Young, William J.
In the nineteenth century, transit was the most important surveying device in the United States. However, the form’s inventor, William J. Young, saw it as only a modification of his new railroad compass when he created it in 1831.
