    AI Overview
    OEM MEMS accelerometer calibration involves factory-level laser trimming of silicon structures for precision and, for high-performance units, back-to-back calibration against reference sensors on shakers, with ISO/IEC 17025 accredited labs providing traceable, detailed reports for sensitivity, bias, and axis alignment. Key manufacturers like
    PCB Piezotronics ensure accuracy in DC MEMS through specialized, automated calibration systems.
    OEM MEMS Calibration Techniques
    • Factory Laser Trimming : During manufacturing, laser trimming tightens tolerances on the silicon, ensuring consistent, stable, and pre-calibrated sensors.
    • Static 1g Calibration : The sensor is oriented in
      1 g 1 g
      1 𝑔
      fields (e.g., flipping +1g to -1g) to determine sensitivity and bias.
    • Back-to-Back Comparison : The MEMS sensor is mounted alongside a, known, higher-precision reference accelerometer on a shaker, comparing output signals.
    • Frequency Response Testing : The device is subjected to a range of frequencies (e.g., 2 Hz to 2 kHz) to check for amplitude and phase accuracy.
    Top Calibration Manufacturers & Systems
    • The Modal Shop (a PCB Piezotronics company) : Offers automated, ISO 17025 accredited calibration systems like the 9155.
    • Brüel & Kjær (HBK) : Providesportable, battery-powered shakers for field, and lab calibration.
    • LAB Motion Systems : Specializes in high-precision motion stages for calibrating advanced MEMS, FOG, and inertial sensors.
    • PCB Piezotronics : Manufactures and calibrates both piezoelectric and MEMS-based (Variable Capacitance/Piezoresistive) accelerometers.
    Critical Considerations
    • Traceability : Calibration must be traceable to national standards (e.g., NIST).
    • Calibration Interval : While MEMS are robust, annual calibration is typically recommended, or immediately if the sensor exceeds temperature limits or is dropped.
    • Digital Accelerometers : Calibration of these units can be more complex, often requiring specialized, non-standardized procedures.
