Key Specifications

Measurement Ranges (Software‑configurable)

‑ Three optional ranges: ±1.5 g / ±3 g / ±6 g‑ Filter: 10 Hz low‑pass filter available for ±1.5 g; 70 Hz low‑pass filter supported for all ranges‑ Noise Density: 37 µg/√Hz‑ Temperature Zero‑point Drift: X/Y ±10 mg, Z‑axis ±15 mg‑ Built‑in mechanical damping suppresses external vibration interference and ensures stable output under heavy‑vibration conditions.

Core Functions

‑ Output raw X/Y/Z three‑axis digital acceleration data for MCU to calculate tilt and inclination angles.‑ Three‑range switching: small ±1.5 g range for tilt measurement; ±3 g / ±6 g for shock and vibration detection.‑ Unique mechanical‑damping structure maintains stable output under strong‑vibration working conditions and provides high immunity to vibration disturbance.‑ Hardware self‑diagnosis reports sensor faults in real time to improve overall system reliability.‑ SPI digital output, no external ADC required. Can be paired with external gyroscopes to construct IMU inertial measurement units.

Application Scope

Construction Machinery & Leveling Systems

Tilt monitoring for aerial work platforms, cranes and construction machinery; professional spirit levels and automatic platform‑leveling systems.

IMU Inertial‑Measurement Support

Combines with external gyroscopes to form inertial measurement units; navigation and attitude modules; attitude sensing for heavy‑duty equipment.

Industrial Equipment Vibration Monitoring

Vibration‑status acquisition for industrial equipment; equipment motion analysis and motion control.

Structural Health Monitoring (SHM)

Monitoring for steel towers, wind‑power facilities and foundation pits; deformation monitoring of buildings under severe‑vibration environments.

Non‑Safety‑Related On‑board Applications
