  2. Small arms ammunition pressure testing - Wikipedia

    en.wikipedia.org/wiki/Small_arms_ammunition...

    SAAMI pressure testing protocol uses a conformal piezoelectric quartz transducer for pressure testing of centerfire pistol and revolver, centerfire rifle, and rimfire cartridges. The primary source of the conformal transducers is the US company PCB Piezotronics. The SAAMI pressure testing protocol uses test barrels that have a hole located in ...

  3. Pressure measurement - Wikipedia

    en.wikipedia.org/wiki/Pressure_measurement

    Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area.

  4. 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 ...

    The other two columns are partially filled. The top of both the main column on the right and the reservoir column on the left are connected together and to an inlet for the pressure to be measured. When the test pressure is applied, the mercury rises in both the left and right columns and falls in the centre column.

  6. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then revalidated at regular intervals according to the relevant standard.

    This pressure is then transmitted to a hydraulic pressure gauge via a high pressure hose. [4] The gauge's Bourdon tube senses the pressure and registers it on the dial. Because this sensor has no electrical components, it is ideal for use in hazardous areas. [5] Typical hydraulic load cell applications include tank, bin, and hopper weighing. [6]

  9. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    The pressure differential is typically measured using diaphragm pressure transducers with digital readout. Since these meters have significantly lower permanent pressure losses than orifice meters, Dall tubes are widely used for measuring the flow rate of large pipeworks.
