The Model 9155C accelerometer calibration workstation from The Modal Shop Inc.
, Cincinnati, OH, lets you calibrate ICP, charge, shock, piezoresistive, capacitive, velocity, high-frequency, and low-frequency vibration sensors for sensitivity and phase and verify them for linearity or resonance. Calibrations are performed using the back-to-back method according to ISO 16063-21. An air-bearing shaker, with expanded frequency range to 20 kHz, is available for those who want ultra-low transverse motion. You can also get configurations to allow you to calibrate low-frequency sensors down to 0.5 Hz, perform resonance testing up to 50 kHz, calibrate shock sensors from 20–10,000 g, and check linearity to 40 g.
