peak pressure value to ensure a safe use of the weapon. Earlier, until the mid of the 1960s, the crusher gauge method, invented in 1860s by Nobel, was the only commonly used and standardized method for gas chamber pressure measurement [1]. A copper or lead cylinder is compressed by a piston fitted to a piston hole into the chamber of the barrel.

The formula for pressure determination; P = KW W is the weight of powder in grains K is the constant value There are three methods generally used to determine the pressures. • Crusher technique • Piezo technique • Strain gauge method . Crusher Technique . The measurement of maximum chamber pressure is carried out with a pressure gun.
However, crusher pressure deformation at high pressures deviates from the corresponding values measured by piezoelectric pressure transducers due to strain rate dependence of copper.
chamber pressure was the copper crusher method. Up until that time, what we now call CUP was commonly known by two different names: CUP and PSI. The two were used practically interchangeably. Of course, this use of PSI was incorrect. It wasn't much of a problem until piezoelectric and strain gauge systems became commonly available. These
