Conformal Transducers and Kistler 6203 Transducers for Measuring Chamber Gas Pressure in Small Arms Ammunition.

摘要

Today, copper crusher gauges have largely given way to quartz piezoelectric transducers for the measurement of pressure in small calibre gun firings. Recent developments in piezoelectric transducers have resulted in the creation of the conformal gauge. This device, fitted semi-permanently in the proof barrel, measures gas chamber pressure by directly sensing the resultant forces on the cartridge case. This report gives results of comparisons made between PCB type 117B conformal transducers and NATO approved Kistler 6203 transducers for the measurement of pressure of 7.62 mm and 5.56 mm calibre NATO ammunition in proof barrels....
