688A06 Triaxial Vibration Sensor

688A06 Triaxial Vibration Sensor (Ultra-High-G IEPE Block Type)

The 688A06 series is an industrial-grade, multi-axis triaxial vibration sensor designed to execute simultaneous three-dimensional acceleration measurements under extreme mechanical shock and ultra-high-g dynamic profiles. Featuring an integrated IEPE (Integrated Electronics Piezo-Electric) internal amplifier network, this low-impedance transducer conditions raw dynamic events on-board, delivering a stable voltage output that eliminates triboelectric cable noise during severe physical displacements. Purpose-built for hyper-velocity impact diagnostics, the 688A06 integrates an exceptional ±20000 dynamic measurement range with an ultra-stiff structural architecture yielding a resonant frequency ≥70 kHz , making it an essential instrumentation tool for near-field ballistics, pyroshock simulation, and high-energy weapons testing.
