Copper units of pressure - Wikipedia

Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms. These 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 replacedPressure Measuring Through Copper Crushers,Pressure Measuring Through Copper Crushers.

In addition to these specially made barrels, standard rifle, pistol, and shotgun barrels are also sometimes instrumented for pressure measurements.Chamber pressure - Wikipedia,Copper crusher method. Through the mid-1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls. When a cartridge is fired, it compresses the copper slug. It is then removed, measured, and compared to the original dimensions. Using the known properties of copper, the chamber pressure,crushers copper gauze for pressure measurement,Pressure measuring through copper crushers calibration of crusher pressure gauges by high strain rate testing gun pressures can be measured by socalled crusher pressure gauges which are based on the strain rate dependence of the deformation behavior of copper values of the elements through the common d hallpetch dependence.

COPPER CRUSHER. The copper crusher is a mechanical procedure in which a test barrel is modified to contain a small piston installed over a . drilled cartridge case. Figure 3 on page 5 shows a cross-section of a typical copper . crusher installed onto a pressure barrel. In this pressure measurement system, a small hole is drilled through one wall of the case in line with the piston hole,Chamber pressure - Wikipedia,Copper crusher method. Through the mid-1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls.

There is no direct correlation between this antique pressure measurements to the modern Piezo Transducer. So while it is an interesting footnote it is no longer a useful measurement technique for modern ballistics.The old method of pressure measuring was the copper,,The old method of pressure measuring was the copper-crusher (or lead, in some pressure ranges) method. A test barrel, with a hole in the chamber, had a small copper cylinder held in place over the hole. When fired, the gases hammered the copper cylinder (escaping out through the provided hole) and the impact of the pressure shortened the cylinder.
