Bubble Levels

The production of these articles, started in the early 1970s, was prompted by requests from clients in the weighing industry who required us to supply the circular bubble levels to line up the instruments.

Since then the product range has expanded greatly so that we now work in fields as varied as construction, the crane industry, various instrumentation industries, photography, tripods for photo-videos, geodetic equipment and lifting platforms.

Wherever there is a need for rapid centering our products can satisfy that need.

Whatsmore we can respond to any special customer request be it for a special sensitivity, a non-standard graphic or his own company logo printed on an advertising article for example.

In the different sections you will be able to find the article best adapted to your needs, not forgetting of course that we are always open to evaluate your individual requirements.

A brief note on sensitivity

The choice of a bubble level determines how accurate the horizontal position of an instrument or machine will be.
Sensitivity has a key role in your choice a level indicator because it directly effects the accuracy of any measurement.
It is defined as the angle or gradient change required to move the bubble a determined distance. The standard is normally 2mm /m (millimeters per meter).
For the angle the units of measurement are degrees (°), minutes (‘) and seconds (”) where 1° corresponds to 60′ and 1’ corresponds to 60”.
For the gradient the unit of measurement is mm/m.

The senstivity is calculated by the radius of curvature of the inner case inside the vial, in which the bubble moves.
The greater the radius of curvature the higher the sensitivity of the level indicator and conversely a reduction in the radius will result in a reduction in sensitivity.

As a practical example we can try, with the bubble centralised , a shift of 2mm to verify that the level indicator has a sensitivity of 5° per 2mm bubble movement.
This may also be expressed as a gradient, where 5° corresponds to a gradient of 87 mm/m.
So this means that if we position the bubble level on a flat surface that is 1m in length and lift one side to a height of 87mm this will create an angle of 5° which will cause the bubble to move 2mm.
