A pressure-measuring device called the electronic crusher gauge is described. The volume of the gauge is small enough (38 cm3) that it can be placed in the powder chamber of large- or medium-caliber guns, with chamber volume not less than 4 dm3. The gauge is characterized by digital data recorded with a sampling frequency from 0.1 to 100 kHz and directly transmitted under PC control. The measuring principles and construction features of this gauge are detailed, a bore pressure curve for a certain type of gun is given, and the results are compared with those measured by a conventional copper crusher gauge.
