To this day, most published chamber pressure data for metallic cartridges is taken by the copper crusher method of measurement. the proper name for this type of measurement is cup, or copper units of pressure. another, similar, method uses lead crusher pellets and the resulting pressure values are called lead units of pressure, or lup.pressure measured by copper crusher gauge is always less than the true pressure due to the following reasons inertia inherent in the system once a round is fired for pressure measurement the process starts with the burning of primerignition of propellant hence burning of propellant

mil gauge: the mil copper is approximately times thicker than typical household aluminum foil and 1.5 times thicker than the mil. this is a heavy-duty tooling foil. mil can be cut fairly easily with scissors and is still very pliable. It may hold shape a little better than the mil, but will not bear much weight and will yield to increasing pressure.pcb manufactures sensors used by design engineers and predictive maintenance professionals to test and measure vibration, pressure, force, acoustics, load, and shock in research and development as well as industrial applications. contact 3425 walden avenue depew, NY 495 usa 800.828.8840 716.684.0001 716.684.0987 companies pcb group, inc. was acquired by mts systems corporation
