Make an impression with our series of bar accelerators.

Comprised of several different barrel diameters, lengths, and pressure ratings for various test scenarios including split-Hopkinson pressure bar and direct impact, Bar Accelerators can be configured with manual controls or with remote push-button charge, vent, and fire operation. REL Bar Accelerators can be operated in both tension and compression with minimal changeover time and can repeatedly launch SHPB strikers or impact projectiles to within 1% accuracy.
