688A09 IEPE Triaxial Accelerometers (High-G Miniature Cube Type)

The 688A09 series represents a premium class of IEPE triaxial accelerometers engineered to execute simultaneous multi-directional vibration and high-amplitude shock profiling within tightly constrained spaces. Featuring integrated internal IEPE (Integrated Electronics Piezo-Electric) signal conditioning circuitry, these low-impedance transducers convert raw internal charge into a stable voltage output, allowing for distortion-free data transmission over extended cable distances. Specially optimized for high-velocity dynamic testing, the 688A09 combines a robust 2500 g measurement envelope with an ultra-rigid internal configuration yielding a resonant frequency 70kHz, delivering definitive accuracy for aerospace modal testing, high-impact crash diagnostics, and military rocketry research.

Key Features

• True Three-Axis Orthogonal Integration: Combines independent, isolated sensing crystal structures along three mutually perpendicular axes within a singular cubic housing, minimizing mounting footprints and accelerating multi-directional data correlation.

• Low-Impedance Integrated IEPE Electronics: Utilizes internal excitation circuitry that matches on-board impedance requirements to deliver a reliable voltage signal, suppressing triboelectric line noise and environmental electromagnetic interference.

• High-G Impact & Dynamic Survivability: Engineered to withstand sudden, transient mechanical shocks up to 8000g pK and continuous cyclical high-frequency vibration fields up to 4000 g pk under intense test profiles.

• Broad 10 kHz Linear Operating Zone: Achieves an exceptional mounted natural resonant frequency  70 kHz, ensuring excellent frequency tracking response and minimal phase shifting from 5 to 10,000 Hz .
