Ways to Measure Pressure | The Ballistic Assistant
During calibration the pressure is pumped up to 4 or 5 increasing pressures. The transducer measurement is read, and recorded. By the end of the test a pC/PSI and a pressure offset is established. This offset it the amount of pressure that is required to expand the case to touch the sensor.

Copper crushers
Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.
