An external stress gauge is placed on the outside of the barrel. This is not a process I am familiar with, so I will hold off on going into the details on how it is performed. The Basic Equipment …

A pressure-measuring device called the electronic crusher gauge is described. The volume of the gauge is small enough (38 cm/sup 3/) that it can be placed in the powder chamber of large- or medium-caliber guns, with chamber volume not less than 4 dm/sup 3/. The gauge is characterized by digital data recorded with a sampling frequency from 0.1 to 100 kHz and directly transmitted …

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 ...

This study examined the operation of a pressure gauge for measuring the internal pressure of a barrel. During the ammunition performance evaluation test, the internal pressure of the barrel was measured mainly using a copper crusher gauge. The internal piezo gauge (IPG) was used to replace the pressure measurement method, and the test results were analyzed to verify the …
