gauge

, gage
1. a standard measurement, dimension, capacity, or quantity
2. any of various instruments for measuring a quantity
3. any of various devices used to check for conformity with a standard measurement
4. the thickness of sheet metal or the diameter of wire
5. the distance between the rails of a railway track: in Britain 4 ft. 8½ in. (1.435 m)
6. the distance between two wheels on the same axle of a vehicle, truck, etc.
7. Nautical the position of a vessel in relation to the wind and another vessel. One vessel may be windward (weather gauge) or leeward (lee gauge) of the other
8. a measure of the fineness of woven or knitted fabric, usually expressed as the number of needles used per inch
9. the width of motion-picture film or magnetic tape
10. (of a pressure measurement) measured on a pressure gauge that registers zero at atmospheric pressure; above or below atmospheric pressure

Gauge

To shape a brick by rubbing or molding it into a particular size.

Gauge

 

a scaleless measuring device designed for checking the dimensions, shape, and relative positions of the parts of articles. The checking consists in a comparison of the dimensions of a product with a measuring gauge in terms of the fit or degree of contact of their surfaces. This comparison makes possible classification of products as acceptable (if the dimensions lie within tolerance limits), defective (with repair possible), or irreparable.

The most widely used limit (go-no go) gauges are go gauges, which are made according to the minimum limiting size of an opening or the maximum size of a shaft and fit into acceptable products, and no-go gauges, which are made for the maximum size of an opening or the minimum size of a shaft and will not fit into acceptable products. Gauges are also classified according to purposes: working gauges, used for testing products at the manufacturing plant; acceptance gauges, used by the consumer for rechecking products; and reference gauges, which are used for testing or regulation of working and acceptance gauges. The advantages of gauges are simplicity of design and the possibility of integrated checking of products of complex shape; disadvantages include low versatility and the inability to determine actual size deviations. The use of these gauges in machine building is decreasing because of the introduction of universal measuring methods and mechanized and automatic devices.

gauge, gage

1. The thickness of sheet metal or metal tubing, usually designated by a number.
2. The diameter of wire or a screw, usually designated by a number.
3. The distance between two points, such as parallel lines of connectors.
4. A strip of metal or wood used as a guide to control the thickness of a bituminous or concrete paving; called a screed when used in plastering.
5. A measuring instrument, esp. one for measuring liquid level, dimensions, or pressure.
7. In roofing, the length of a shingle, slate, or tile that is exposed when laid.
8. The quantity of gauging plaster used with common plaster (lime putty) to hasten its setting, etc.
9. To mix gauging plaster with lime putty, to effect better control of the set, to prevent shrinkage of the lime putty, and to increase its strength.
10. To cut, chip, or rub stone or brick to a uniform size or shape.

gauge
i. Any pressure, temperature, or flow-measuring instrument.
ii. A standard measure of sheet and wire thickness. The higher the number, the lesser the thickness.
iii. A hand comparator for a GO/NO GO check on an exact dimension or a screw thread.
