Model 68CM1 Triaxial Accelerometer - Specifically crafted for ATD dummy instrumentation, the Model 68CM1 sets a new benchmark in crash test analysis with its WorldSID approval and exceptional performance across a dynamic range of ±50g to ±2000g. This accelerometer excels in providing best-in-class frequency response, linearity, transverse sensitivity, and minimal long-term drift, thanks to its advanced piezoresistive sensor technology. Its full-bridge configuration with a nominal 4000Ω impedance ensures quick warm-up times and stable performance, distinguishing it from other models. Compliant with both SAE J211/J2570 and ISO 6487 standards, the Model 68CM1 features less than 1% transverse sensitivity, making it a unique choice for accurate triaxial crash acceleration measurement. Encased in a compact stainless steel housing, it offers exceptional shock survivability and a flat frequency response of up to 4000Hz across all axes. With features like optimum gas damping and a fast warm-up time of under 10 seconds, this accelerometer is ideal for use in WorldSID dummies, ejection seat testing, and various automotive safety testing applications, ensuring precise and reliable data for critical safety evaluations.
