Sensitiveness of a Level Tube (With Diagram)| Levelling | Surveying
Sensitiveness or the sensitivity of a level tube is its capability of exhibiting small deviations of the tube from the horizontal. This quality depends mainly upon the radius of curvature of the level tube which may vary from 10 to 300 metres —the larger the radius, the greater the sensitiveness. Sensitiveness is also increased by increase in the length of [...]
