Electronic, self-contained and encapsulated high pressure recorder
One major requirement by manufacturers and users of large calibre ammunition across the world and within NATO is to accurately measure the gas pressure without any adaptation to the gun. The classical methods for pressure measurements of large calibre ammunition are still either by means of copper crushers or by piezoelectric transducers mounted in breech or barrel or with cartridge case adapters. In addition external charge amplifiers, sensitive piezo-cables and data processing are needed.
The third generation B251-150 IPG from HPI meets the new requirements and features simpler, faster and in autonomous operation with integrated charge amplifier, onboard memory combined with high accuracy and safety. The system based on STANAG basically consists of a rugged steel housing of small dimensions surviving in harsh environments, containing built-in piezoelectric transducer, micro-module (data acquisition) with battery. The influence of the extremely small volume of about 22 ccm to measuring results is neglectable. This cannot be guaranteed for gages of larger volumes.
