A spirit level, bubble level, or simply a level, is a device designed to indicate whether a surface is horizontal or vertical. Of course, there are levels for determining degrees of deviation, but we’ll talk about that later.
There are different types of levels intended for use by professionals such as carpenters, construction workers, surveyors, welders and other metal workers, and in photography or video work, etc.
Everyone should have a level!!!!
Once upon a time, levelers had tubes containing slightly curved glass vials with a constant inner diameter at each viewing point.
These vials are partially filled with a liquid, usually colored alcohol or spirit, leaving a bubble in the tube.
They have a slight upward curve, so the bubble naturally rests in the center, the highest point.
At slight inclinations the bubble moves away from the marked central position.
Alcohol has low viscosity and surface tension, which allows the bubble to move quickly inside the tube and settle precisely.
Calibration, and quality control –
We at B-Tech Tools know how to do this simply.
To check the accuracy of the spirit level, a perfectly horizontal surface is not required.
The spirit level is placed on a flat surface and one side of the center of the bubble is marked with the value visible on the bubble tube.
This reading indicates the extent to which the surface is parallel to the horizontal plane, which at this point is precisely unknown.
The level is then rotated 180 degrees in the horizontal plane, and another check is noted.
If the level is accurate, it will indicate the same point in the same direction relative to the horizontal plane.
This implies that the level is accurate.
There are different types of plates for different uses:
Water levels of various lengths
Cast plates for tapping with a rubber hammer
Pocket spirit level
A torpedo plane is usually 23 cm long and is very useful.
Goalkeepers
Wooden pallets
Laser level
And the list is long!!!
How are plates made?
The panels are made from a variety of materials including aluminum, plastic, wood, cast iron, and composite materials.
There are other functional level features beyond style and material such as magnetism, bubble type, and durability.
Some pliers are magnetic and are ideal for construction with metal, or a plumber or electrician working around pipes.
The strength of a magnet compared to the weight of the level is an important test of quality:
N42 magnets manufactured at B-Tech Tools are the strongest.
Some levels have replaceable level bubbles.
The levels are also made more durable with the inclusion of covers for the level bubble and side protectors made of various materials such as rubber and plastic to protect the bubbles from end to end to withstand the shock of a fall.
Some levelers have hand grips, which are mainly designed for comfort.
The history of the plateau is briefly discussed in an 1887 article.
A French scientist, he invented the device some time before February 2, 1661.
Within a year of this date, the inventor had disseminated details of his invention to others, including Robert Hooke in London and Vincenzo Viviani in Florence.
It is occasionally claimed that these “bubble levels” did not come into widespread use until the early 18th century, the earliest surviving examples being from that period, but Adrien Ozotte recommended that the Académie Royale des Sciences take Thevenot-type levels on an expedition to Madagascar in 1666.
It is very likely that these plates were used in France and other places long before that.
