copper crusher pressure measurement tools Function Photo
copper crusher pressure measurement tools Authors: F. Coghe1 L. Elkarous2 P. van de Maat3 A ORBi It is widely known that the result of a chamber pressure measurement is dependent upon the modeling of the dynamic compression of the copper crusher inside the chamber was used use of these devices only began in the mid of 1960s.
Metallic Cartridge Chamber Pressure Measurement
To this day, most published chamber pressure (MAP) 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.

Copper Unit of Pressure (CUP) Defined by Hodgdon « Daily
Apr 18, 2015· A: Copper Unit of Pressure (CUP) is a measurement used in the ammunition industry to determine the chamber pressure created by a cartridge load. Originally, a precisely formed copper slug was placed in a fixture over the chamber. When the cartridge was fired, the amount of crushing measured on the slug allowed engineers to determine the pressure.
Experimental techniques for ballistic pressure
The piezoelectric transducers and the copper crusher gauge can be installed in the same mounting position in respect to barrel length but displaced by 90 degrees to each other. The copper crusher gauge had a nominal height of 4.91 mm and a nominal diameter of 3.0 mm. Figure 2. Transducers and crusher installation Figure 3. Copper crusher gauge

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.
