crusher type pressure gauges are used to determine the maximum pressure in the barrel, or in a ballistic bomb, during a ballistic test. list of types offered: cylinder crushers, conical crushers brass products copper products high performance copper alloy products/lead frame material nickel silver products others phosphor bronze products
the gas check, piston, and copper crusher are installed and retained with the thumb screw. when fired, the gases vent out through the drilled hole and expand the gas check into the piston hole, forming a seal. the resulting pressure acting on the piston forces the copper crusher into a permanent deformation. the crusher is removed and carefully
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.

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 setup.
a potential disaster. in the meantime, the rfq was moving forward, and cox manufacturing cox of san antonio, texas, was chosen by saami as the preferred vendor for this production run of what was rapidly becoming known internally at saami as the infamous rfpi copper crusher. the choice of cox fig.
a chamber pressure measured with a copper crusher gauge would be expressed as psi cup in the english system or mpa cup in the metric get price calibration of crusher pressure gauges by high strain rate testing
in the avoirdupois system, the units of pressure are pounds per square inch and in the metric system, the units or pressure are newtons per square meter pascals . a chamber pressure measured with a copper crusher gauge would be expressed as psi cup in the english system or mpa cup in the metric system.
mil-dtl-49514 - copper crusher spheres for cannon and mortar pressure gauges, general specification for published by npfc on december 14, 2016 this specification covers copper crusher spheres for use in crusher gauges, primarily intended for use in measuring pressures in weapons.
crusher gauge function crusher gauges are designed to determine propellant gases maximum pressure, during a shot in a gun combustion chamber, as well as in a pressure gauge bomb. the sensor is copper crushers of different configurations such as piston, conical, spherical.
crusher gauge and piezoelectric pressure transducer 2 . the crusher method is based on the measurement of the deformation of copper element due to the pressure resultant force on the piston of crusher gauge. the crusher method gives an estimate of peak gas pressure of shot in gun chamber. the accuracy of estimated crusher pressure value is a
