Across various industries, measuring the pressure of a substance is an important part of the manufacturing process. Obtaining accurate and meaningful data is important in determining the quality and consistency of the product. For these reasons, accurate sensors are absolutely critical in obtaining this information.

Gauge pressure is zero-referenced against ambient pressure and is used in most applications operating in, but not with, ambient air, such as in fluid power systems.

Pressure gauges are used to measure the instantaneous pressure during both evacuation and venting, the signals being passed to a control unit which opens and closes the valves in the system according to a preset program which ensures that each of the pumps in the system operates in its optimum pressure range.

Gauge, also spelled gage, in manufacturing and engineering, a device used to determine, either directly or indirectly, whether a dimension is larger or smaller than another dimension that is used as a reference standard.

B. Description of Measuring Instruments – The most commonly used device to measure gauge pressure is a Bourdon tube pressure gauge. It is a mechanical device which consists of a tube formed into a C-shape and sealed at one end.

Plug Gauges : These are used for checking holes of many different shapes and sizes. Ring Gauges : External diameter measuring gauges. Snap Gauges : These are used for checking shafts. Thread Gauges : These are used for pitch diameter of the thread. Form Gauges : These are used to check the contour of a profile.

To gauge is to measure or test. The verb gauge means to estimate or measure, while the noun gauge is a tool you can use to make such a measurement. The thickness, or diameter, of an item like wire (or the barrel of a gun) is another meaning of gauge.
