Device for determining projectile velocity, especially at the muzzle of a gun barrel

摘要: A device for determining projectile velocity at a gun barrel muzzle, the including least two sensors spaced some distance apart be integrated on or directly in barrel. During passage of projectile, undergo expansion due to gas pressure base and rotating band inside This is converted an electric signal, which, if necessary, amplified then supplied signal processing connected output side sensors. High-temperature-resistant quartz form longitudinal measuring pins are preferably used as sensors, which installed either carrier ring around
