Multi Axis Acceleration Sensor 688A08

688A08 Multi Axis Acceleration Sensor (High-G IEPE Type)

The 688A08 series is an advanced, industrial-grade multi axis acceleration sensor engineered to execute simultaneous multi-directional vibration and high-amplitude shock measurements across demanding structural applications. Equipped with integrated internal IEPE (Integrated Electronics Piezo-Electric) circuitry, this low-impedance transducer converts high-impedance charge signals on-board, allowing for reliable data transmission over extended cable spans without signal interference. Precision-machined for extreme structural test regimes, the 688A08 pairs a formidable $\pm5000\text{ g}$ dynamic measurement range with an ultra-rigid internal configuration that yields an exceptional resonant frequency $\ge 70\text{ kHz}$, delivering unmatched fidelity for aerospace modal analysis, ballistic testing, and high-g automotive crash diagnostics.

Key Features

• Simultaneous Multi-Axis Dynamic Tracking: Combines distinct sensing elements within a single hermetic block to measure multi-directional acceleration vectors concurrently, cutting down instrumentation installation mass and sensor layout footprint space.

• Integrated Low-Impedance IEPE Electronics: Features onboard signal conditioning circuitry powered over a standard constant-current line, providing a robust output voltage that resists cable motion noise and electromagnetic interference.

• Severe High-G Shock & Motion Containment: Built to endure massive mechanical shock profiles up to 10,000g pk and continuous cyclical vibration fields up to 6000g pk, making it highly survival-rated for high-velocity destructive impact testing.

• Ultra-Broad 10 kHz Linear Bandwidth: Engineered with a mounted natural resonant frequency 70kHz to guarantee a flat, linear frequency operating envelope from 5 to 10,000 Hz  with minimal phase distortion.
