1. Sensing Mechanism

Powered by a high-precision quartz flexible pendulum (comprising a flexible beam and mass block), the accelerometer converts mechanical acceleration into electrical signals. When external acceleration is applied, inertia displaces the mass block, causing elastic deformation of the quartz beam. Deformation magnitude is directly proportional to acceleration intensity, forming the core basis for signal conversion.

2. Signal Conversion

The pendulum cooperates with fixed electrodes to form a capacitive structure. Beam deformation alters the electrode gap, inducing subtle capacitance changes. The built-in high-precision detection circuit captures these minute variations and converts them into linear current signals, achieving seamless transformation from mechanical acceleration to electrical signals.

3. Closed-Loop Calibration

For exceptional accuracy and stability, a closed-loop control system is integrated. After capacitive signals are converted to current, the feedback circuit generates an equal-but-opposite electromagnetic or electrostatic force to reset the pendulum to its equilibrium position. This actively suppresses beam deformation errors, ensuring minimal measurement deviation and long-term operational stability.

4. Temperature Compensation (Optional)

For extreme environment reliability, an optional built-in temperature sensor enables real-time thermal monitoring. A dedicated algorithm dynamically adjusts bias and scale factor parameters based on temperature data, effectively neutralizing quartz material and circuit performance drift. This ensures consistent precision across wide temperature fluctuations, eliminating the need for frequent recalibration.
