Shock Accelerometer Calibration

PneuShock Calibration Exciter | 525 & 535 Options

The PneuShock Shock Accelerometer Calibration Exciter allows users to measure sensor sensitivity at high acceleration levels up to 10 000 g in accordance with ISO 16063-22.  The PneuShock 9155D-525 and 535 options integrate with the Calibration Workstation Model 9155D to support calibration of a variety of accelerometer types.  The 9155D-535 options offers operation in an automated mode for less hands on time by the user making shock tests quick, easy, and efficient.

The state-of-the-art shock exciter makes use of a pneumatically operated projectile to strike an anvil and excite the sensor. By controlling the air pressure and the duration of which the pressure is applied, the user gains greater control and consistency of the impacts. The system can used as a stand alone turnkey set up, including a PC, data acquisition card and signal conditioning, or can be added on to a 9155D calibration Workstation. In either case, the system stores shock calibration results using Microsoft Access via the easy-to-use 9155D software interface.

Highlights

  • Assures accurate, NIST and PTB traceable calibrations
  • Provides calibration and linearity check from 20 g to 10 000 g
  • Automated test control via 9155D software reducing hands on time of calibration
  • Pneumatically actuated exciter delivers controlled and consistent impacts
  • Impact anvils and projectiles included to tailor the impulse shape
  • Compatible with standard back-to-back shock reference accelerometers
  • Provides graphical indication of sensor amplitude linearity

The Accelerometer Calibration Workstation Model 9155 also features back-to-back comparison calibration of piezoelectric (PE), capacitive (VC), and piezoresistive (PR/MEMS) mode accelerometers for both sensitivity and phase according to ISO 16063-21. Printed certificates fulfill the requirements set forth by ISO 17025 for calibration certificates.
