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<\/span>\u00a0measurement envelope with an ultra-rigid internal configuration yielding a resonant frequency 70kHz<\/span>, delivering definitive accuracy for aerospace modal testing, high-impact crash diagnostics, and military rocketry research.<\/p>\n True Three-Axis Orthogonal Integration:<\/b> 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.<\/p>\n<\/li>\n Low-Impedance Integrated IEPE Electronics:<\/b> Utilizes internal excitation circuitry that matches on-board impedance requirements to deliver a reliable voltage signal, suppressing triboelectric line noise and environmental electromagnetic interference.<\/p>\n<\/li>\n High-G Impact & Dynamic Survivability:<\/b> Engineered to withstand sudden, transient mechanical shocks up to 8000g pK<\/span> and continuous cyclical high-frequency vibration fields up to 4000 g pk<\/span>\u00a0under intense test profiles.<\/p>\n<\/li>\n Broad 10 kHz Linear Operating Zone:<\/b> Achieves an exceptional mounted natural resonant frequency \u00a070 kHz<\/span>, ensuring excellent frequency tracking response and minimal phase shifting from 5 to 10,000 Hz .<\/p>\n<\/li>\n<\/ul>\n <\/p>\nKey Features<\/h3>\n
