copper crusher pressure

Copper units of pressure - WikipediaThese terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively. In recent years, they have been replaced by the adoption of more modern piezoelectric pressure gauges that more accurately measure chamber pressures and generally.copper crusher pressure,Metallic Cartridge Chamber Pressure Measurement - Chuck HawksLead is more easily deformed than copper, and the LUP method is normally used for measuring relatively low chamber pressures, such as those generated by shotgun shells, while copper crushers (CUP) are used for measuring the pressure of handgun and rifle cartridges. LUP and CUP numbers are not interchangeable,.

Differences in pressure measurement systems - Shooters ForumJun 21, 2014 . Only SAAMI segregates copper crusher and Piezo transducer results with different units (CUP and psi). Everyone else uses the same pressure units for both, be it psi, MPa, or bar (tenths of an MPa), and you just have to have the inside track on which instrument made the measurement to know what you are.copper crusher pressure,Copper crushers crusher pressure gauges - PrototypaResearch, development and manufacture of ballistic measuring devices.
