2. Deadweight tester - Wikipedia

   en.wikipedia.org/wiki/Deadweight_tester

   A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston. Deadweight testers are secondary standards which means that the pressure measured by a deadweight tester is defined through other quantities: length, mass and time.

3. Calibration - Wikipedia

   en.wikipedia.org/wiki/Calibration

   As an example, a manual process may be used for calibration of a pressure gauge. The procedure requires multiple steps, [12] to connect the gauge under test to a reference master gauge and an adjustable pressure source, to apply fluid pressure to both reference and test gauges at definite points over the span of the gauge, and to compare the ...

4. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   Example of the widely used Bourdon pressure gauge Checking tire pressure with a spring and piston tire-pressure gauge. Pressure measurement is the measurement of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area.

5. Mercury pressure gauge - Wikipedia

   en.wikipedia.org/wiki/Mercury_pressure_gauge

   The parent of all mercury pressure gauges is the mercury barometer invented by Evangelista Torricelli in 1643. [15] An early engineering application of the mercury pressure gauge was to measure pressure in steam boilers during the age of steam. The first use on steam engines was by James Watt while developing the Watt steam engine between 1763 ...

6. Load cell - Wikipedia

   en.wikipedia.org/wiki/Load_cell

   For example, in the case of a 60 tonne load cell, then specific test weights that measure in 5, 10, 20, 40 and 60 tonne increments may be used; a five step calibration process is usually sufficient for ensuring a device is accurately calibrated. Repeating this five-step calibration procedure 2-3 times is recommended for consistent results. [16]

   MSA analyzes the collection of equipment, operations, procedures, software and personnel that affects the assignment of a number to a measurement characteristic. A measurement system analysis considers the following: Selecting the correct measurement and approach; Assessing the measuring device; Assessing procedures and operators

9. Go/no-go gauge - Wikipedia

   en.wikipedia.org/wiki/Go/no-go_gauge

   Hardened and ground plug gauge Replaceable thread and plug gauges. These gauges are referred to as plug gauges; they are used in the manner of a plug.They are generally assembled from standard parts, where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type gauge blocks) and a body that uses the collet principle to hold the gauges firmly.
