Its standout feature is the ultra-low noise density of 25\u00b5g\/\u221aHz, which enables detection of incipient bearing faults and gear mesh abnormalities that lower-performance accelerometers would miss. The 11kHz bandwidth (X\/Y axes) captures the high-frequency harmonics critical for diagnosing bearing defects. The device provides both analog and 16-bit SPI digital outputs, offering flexibility for system integration. An integrated temperature sensor facilitates thermal compensation algorithms. The 5x5mm LFCSP package is suitable for space-constrained sensor nodes.","working_principle":"The ADXL1002 uses Analog Devices' iMEMS technology with a polysilicon surface-micromachined sensing element. Each axis contains a differential capacitor structure whose plates move under acceleration, modulating the capacitance. An on-chip amplifier and demodulator convert this capacitance change to a voltage proportional to acceleration. The analog output provides a continuous real-time signal, while the integrated ADC digitizes the output at up to 16-bit resolution via the SPI interface. The signal conditioning path includes anti-aliasing filtering and offset correction. The aligned phase response across all three axes ensures accurate modal analysis and cross-axis correlation.","pin_description":"

      • Motor Bearing Fault Detection:<\/b> Mount the ADXL1002 on a motor housing to capture vibration signatures. The 25\u00b5g\/\u221aHz noise floor detects early bearing wear patterns (ball pass frequency harmonics) months before failure. Use FFT analysis on the analog output to identify specific fault frequencies. The \u00b150g range accommodates both low-frequency imbalance and high-frequency bearing tones.<\/li>
      • Structural Health Monitoring:<\/b> Install on bridges, wind turbines, or building structures to monitor vibration modes. The aligned phase response across axes enables accurate operational modal analysis (OMA). The 11kHz bandwidth captures structural resonances in stiff structures. Low power enables solar or battery-powered wireless sensor nodes.<\/li>
      • Industrial Gearbox Monitoring:<\/b> Detect gear mesh abnormalities through high-frequency vibration analysis. The 16-bit SPI output provides high dynamic range for simultaneously monitoring low-speed shaft imbalance and high-speed gear mesh harmonics. Temperature sensor output compensates for thermal drift in continuous monitoring applications.<\/li><\/ul>","alternative_models":"
