chamber can accommodate four electrical transducers and four M-ll copper crusher gages. This device is used to develop the relationship between copper sphere deflection and pressure level that is presented in copper crusher gage tarage tables. For each type of transducer, U samples were placed in the oorts of the hydrodynamic generator.

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.

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 .
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
Copper-Crusher Function #1: Measuring Barrel Chamber Pressure In order to ensure consistent and standard design of ammunition, it is necessary to measure the barrel chamber pressure (Fig. 3) generated by ignition of ammunition cartridge powder in the firing chamber of a barrel. This allows ammunition manufacturers to ensure and demonstrate that ...
Saami Pressure Chart Page 2 Shooters Forum. Its an article with some history the first piezo gun pressure measuring device was made in 1922 the copper crusher was invented in 1860 and it presents data on a copper crusher vs.A non-conformal type piezo transducer gas sampling that is co-installed on the same.30-06 barrel.The tests are done by h.P.White laboratories.
Gun chamber pressure is an important parameter in proofing of ammunition to ensure safety and reliability. It can be measured using copper crushers or piezoelectric sensor. Pressure calculations in copper crusher method are based on linear plastic deformation of copper after firing. However, crusher pressure deformation at high pressures deviates from the corresponding values measured by ...

Until the mid 1960's the only method commonly used for measuring chamber pressures was the copper crusher. Basically, a hole is drilled in the chamber of a firearm and a crusher chamber is attached to that hole. In this crusher chamber is placed a very precisely manufactured piece of copper.
In the late 1850s, a constantly repeatable means of measuring chamber pressure was devised. It depended on the use of copper or lead "crusher" rods. A port was drilled through the chamber wall of a pressure‐testing barrel, and a steel piston was placed in the port.
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.

Measuring Methods. There are 3 basic methods for measuring chamber pressure: Using a copper crusher; The Piezo method; Attaching a strain gauge to the barrel forward of the chamber; 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.
Metallic Cartridge Chamber Pressure Measurement. The crusher method of determining chamber pressures has been around for a very long time and the methods used have become very rigid and standardized Measuring pressure this way is expensive and tedious but works well if done correctly No method of measuring chamber pressure is accurate If you measure 100 rounds of exactly the same
The 1970s was the start of three decades of transformation and modernization of the firearms and ammunition industry. SAAMI started the transition of the decades-old copper crusher chamber pressure measurement system (CUP) to the modern piezoelectric transducer chamber pressure measurement system (PSI).
The crusher gauge method was the only reliable method of measuring chamber pressures until the 1960s, when cheap piezoelectric devices became available. This method is called the Conformal Transducer method or Piezo method. A piezoelectric transducer (a.k.a. sensor) has the property that it generates electricity as it is crushed.
