The PneuShock™ Model 9525C provides shock inputs for accurate and consistent sensitivity calibrations at high acceleration levels. Shocks are created at accelerations from 20g to 10,000g using a pneumatically operated projectile to strike an anvil and excite the sensor. By controlling both the level and the duration of the air pressure applied, the user gains greater control and consistency of the impacts. The system can be used manually in stand-alone mode or fully computer-controlled.

PneuShock™ works by pneumatically forcing a projectile to impact an anvil to which the sensor under test and the back-to-back reference accelerometer are mounted. Pressure is regulated either manually via a precision pressure regulator or optionally via an electrically controlled regulator that allows remote control of the pressure. When the impact occurs, the anvil lifts off a rubber mount, flies a short distance, and is captured by a cushioned fixture. Desired accelerations and pulse durations are produced using combinations of five anvils with different padding material, one optional supplemental mass, and continuously adjustable pressure settings. PneuShock’s electronics are rack mountable and vibration isolated from the shock exciter. Also, the PneuShock poppet is shock isolated from the structure of the exciter to prevent false triggering by the poppet action during low level accelerations.
