688A04 Triaxial Acceleration Sensor

688A04 High-Temperature Triaxial Acceleration Sensor

The 688A04 is a high-performance, triaxial piezoelectric charge mode acceleration sensor engineered for multi-axis dynamic vibration and high-g shock measurement in extreme environments. Featuring a sensitivity of 0.3 pC/g, an expansive measurement range up to ±20,000 g, and a wide frequency response spanning 5 to 11,000 Hz, this sensor delivers exceptional data integrity across all three orthogonal axes without mass-loading delicate structures. It serves as a 1:1 direct drop-in replacement for industry-standard PCB high-temperature triaxial accelerometers, providing NVH and aerospace test engineers with identical reliability, precise cross-axis isolation, and significantly optimized lead times.

Key Features:

• High Sensitivity: 0.3 pC/g ensures accurate measurements.
• Wide Measurement Range: ±20,000g for high-impact applications。
• Titanium Alloy Construction:Lightweight and durable, ideal for aerospace and industrial use.
• Laser-Welded Sealing:IP68-rated for excellent environmental protection.
• M5 Output Interface:Easy integration with existing systems.

Widely used in industries such as aerospace, automotive, and mechanical engineering. Ideal for testing the structural integrity of components under high – impact forces, like in aircraft landing gear testing and automotive crash simulations
