Cartridge Pressure Standards

Instead stable usually called static pressures are applied to sample crushers and the deformed lengths are recorded After a gun firing the length of the crusher is measured and compared to those found in the static tests Even in the 1800 s it was known that crushers did not accurately measure pressure.

Chamber pressure

Within firearms chamber pressure is the pressure exerted by a cartridge case s outside walls on the inside of a firearm s chamber when the cartridge is fired The SI unit for chamber pressure is the megapascal MPa while the American SAAMI uses pounds per square inch PSI and the European CIP uses bar 1 bar is equal to 0.1 MPa . Regardless of pressure unit used the measuring

Liner wear and performance investigation of primary gyratory crushers

Measurements were made on a coarse crushing chamber where the operating parameters hydroset pressure power draw and capacity were tracked during the lifetime of the set of liners.

Pressure Gauges

Pressure gauges are the simplest most direct way of measuring pressure With a variety of measuring techniques and a wide range of sizes and ranges pressure gauges display pressure at the spot of measurement rather than transmitting the readings to a control or display device They provide an easy way to see pressure at a glance.
