Replacement Level Glass Vial, Spirit Bubble Level, Accurate, with Nib, 35mm x 11mm - Green

Product Information

A variant of the linear spirit level is the bull's eye level: a circular, flat-bottomed device with the liquid under a slightly convex glass face with a circle at the center. It serves to level a surface across a plane, while the tubular level only does so in the direction of the tube. These are handmade, do allow 0.4mm in diameter size fluctuation. We haven't found any with more than 0.35mm (at the max) variation though, in diameter.

Can be used as replacement for spirit bubble levels, spare parts or on their own - Vial cylindrical (Tubular Vial) Sensitivity is an important specification for a spirit level, as the device's accuracy depends on its sensitivity. The sensitivity of a level is given as the change of angle or gradient required to move the bubble by unit distance. If the bubble housing has graduated divisions, then the sensitivity is the angle or gradient change that moves the bubble by one of these divisions. 2mm (0.079in) is the usual spacing for graduations; on a surveyor's level, the bubble will move 2mm (0.079in) when the vial is tilted about 0.005 degree. For a precision machinist level with 2mm (0.079in) divisions, when the vial is tilted one division, the level will change 0.04mm (0.0016in) one meter from the pivot point, referred to by machinists as 5 tenths per foot. This terminology is unique to machinists and indicates a length of 5 tenths of 1 thousandth of an inch. [3] [4] Types [ edit ] Level tool being used to establish horizontality.

A similar procedure is applied to more sophisticated instruments such as a surveyor's optical level or a theodolite and is a matter of course each time the instrument is set up. In this latter case, the plane of rotation of the instrument is levelled, along with the spirit level. This is done in two horizontal perpendicular directions. Making: We then specify the exact type of 'decoration' - the ceramic lines to indicate readings. These lines are then permanently baked for durability (you'd think we describing a cake baking recipe here!) Give us a call at 800.550.8425 and describe your situation.

A traditional carpenter's spirit level looks like a short plank of wood and often has a wide body to ensure stability, and that the surface is being measured correctly. In the middle of the spirit level is a small window where the bubble and the tube is mounted. Two notches (or rings) designate where the bubble should be if the surface is level. Often an indicator for a 45 degree inclination is included. [ citation needed] Line level [ edit ] Measuring elevation with a line level and measuring tape. Combining a spirit level with an optical telescope results in a tilting level or dumpy level. [5] These leveling instruments as used in surveying to measure height differences over larger distances. A surveyor's leveling instrument has a spirit level mounted on a telescope (perhaps 30 power) with cross-hairs, itself mounted on a tripod. The observer reads height values off two graduated vertical rods, one 'behind' and one 'in front', to obtain the height difference between the ground points on which the rods are resting. Starting from a point with a known elevation and going cross country (successive points being perhaps 100 meters (328ft) apart) height differences can be measured cumulatively over long distances and elevations can be calculated. Precise levelling is supposed to give the difference in elevation between two points one kilometer (0.62 miles) apart correct to within a few millimeters.
