2. Ruby pressure scale - Wikipedia

   en.wikipedia.org/wiki/Ruby_Pressure_Scale

   Ruby spectra R1, R2 lines. The ruby fluorescence pressure scale is an optical method to measure pressure within a sample chamber of a diamond anvil cell apparatus. [1] Since it is an optical method, which fully make use of the transparency of diamond anvils and only requires an access to a small scale laser generator, it has become the most prevalent pressure gauge method in high pressure ...

3. Calibration - Wikipedia

   en.wikipedia.org/wiki/Calibration

   The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...

4. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   Using atmospheric pressure as reference is usually signified by a "g" for gauge after the pressure unit, e.g. 70 psig, which means that the pressure measured is the total pressure minus atmospheric pressure. There are two types of gauge reference pressure: vented gauge (vg) and sealed gauge (sg).

5. Gas meter - Wikipedia

   en.wikipedia.org/wiki/Gas_meter

   Gas meter. A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas.Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility.

6. Load cell - Wikipedia

   en.wikipedia.org/wiki/Load_cell

   The load cell is completely filled with oil. When the load is applied on the piston, the movement of the piston and the diaphragm results in an increase of oil pressure. This pressure is then transmitted to a hydraulic pressure gauge via a high pressure hose. [4] The gauge's Bourdon tube senses the

7. 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 ...
