Light screens for velocity measurements, mobile and robust (IP66), 50 … 3000 m/s / 2521A

These light screens are for projectile velocity measurements. They are suited for subsonic, supersonic and near sonic projectiles (50 … 3000 m/s). The system is applicable in challenging environments thanks to IP66.

2521A

These light screens are for projectile velocity measurements. They are suited for subsonic, supersonic and near sonic projectiles (50 … 3000 m/s). The system is applicable in challenging environments thanks to IP66.
Main features / advantages
  • Large velocity range (50 … 3000 m/s)
  • Caliber range: 4 … 40 mm
  • Accuracy down to <0.2% (depending on velocity)
  • Well suited for harsh environments (IP66)

The family Type 2521A is ideally suited to measure projectile velocity. The light screen works in the infrared spectrum. This provides very good measurement accuracy for a wide range of velocities of subsonic and supersonic projectiles. With appropriate filters, the measurement of near sonic projectiles is also easily possible. The light screen is designed to be fully compatible with transient recorder family Type 2529A. The analog output signal provides a high quality representation of the physical projectile shape. This allows to choose the appropriate type of velocity measurement (tip-tip, end-end, or any combination), which works best with the used projectile shape. For projectile clouds (e.g. shotgun pellets), the 2521 is well suited to calculate the center of gravity of the cloud for velocity measurements.
