A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on. [ 1 ] These measuring tools are used in metalworking or metrology to either set or measure vertical distances; [ citation needed ] the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces.
The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale. So for a vernier with a constant of 0.1, each mark on the vernier is spaced 9/10 of those on the main scale.
Height gauge or scribing block — allows lines to be scribed at a preset distance, from the tables surface; Surface gauge — an ungraduated comparison measuring tool that performs much the same function as the vernier height gauge. It is often used in conjunction with a dial indicator and a precision height gauge.
A vernier caliper does not easily lose its calibration, but a sharp impact or accidental damage to the measuring surface in the caliper jaw can be significant enough to displace zero. [29] Digital calipers have zero set buttons, for quick recalibration. Vernier, dial and digital calipers can be used with accessories that extend their usefulness.
Depth gauge or height gauge. Form of marking gauge for marking lines parallel to an edge, by setting the head to a certain distance from the end of the rule. [6] Reference for directly transferring dimensions without needing to take a measurement, minimising measurement errors and inaccuracies. [7]
Vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on. The former type of height gauge is often used in doctor's surgeries to find the height of people. Wire gauge: measuring tool determines the thickness of a wire.
Pierre Vernier (French pronunciation: [pjɛʁ vɛʁnje]; 19 August 1580 at Ornans, Franche-Comté (at that time ruled by the Spanish Habsburgs, now part of France) – 14 September 1637, same location) was a French mathematician and instrument inventor.
Vernier height gauge has been restored as a dedicated article. This page can be used to expand on the other usages of the plain height gauge. Graibeard 12:14, 8 September 2005 (UTC) [ reply ]
