The M-11 Copper Crusher Gage is a device which measures peak pressure developed in the chamber of large caliber weapons This gage is one of two models used by the US Army in testing gun systems and is used for high pressure measurements between 150 and 550 MPa In the Third NATO Crusher Gage Comparison Trials held at Meppen.
Because the indicated pressure from crushers is known to be off, SAAMI many decades ago began referring to the indicated pressure from their tests as "Copper Units of Pressure," a clumsy name commonly shortened to "CUP" For low pressure cartridges such as shotshells, lead is used for the crusher, and SAAMI refers to these numbers as "LUP"
Dynamic Calibration Of Chamber Pressure Transducers
Background Timeline • Circa 1860, use of copper crusher gages began (static calibration used) • Circa 1920, use of electronic chamber pressure transducers began • Circa 1960, dynamic calibration of crusher gages began (25% improvement) • 1990 NATO crusher trials imply 1% difference between US (Tourmaline) and French (Quartz) measurements (Everyone celebrates excellent
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, generally at mid-case location The gas check, piston, and copper crusher are installed and retained with the thumb screw When fired.
When the cartridge fires, pressure pierces the case and drives the piston into the copper crusher This force shortens the crusher and the length is measured Postfiring lengths are compared to calibration tables accompanying each lot of crushers to find the pressure value for each shot

Copper units of pressure Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms , A chamber pressure measured with a copper crusher gauge would be expressed as psi (CUP) in the English s.
CUP - Copper Units of Pressure In this pressure measuring technique a hole is drilled in the chamber and a piston fitted that presses on a calibrated copper slug (or crusher) (Some set ups also drill the cartridge case which changes the results compared to non-drilled cas) The whole assembly is held in place with a yoke
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
Apr 03, 2017· Rimfire Firing-Pin Indent Copper Crusher (part 2) , The RFPI crusher was made of the same material specified in the SAAMI technical manual for the cylindrical pressure measurement used by ballistic test laboratories to measure the chamber pressure generated when a cartridge is fired and served as the firing-pin indent crusher used for testing .
