SCL3400-D01 | Murata High-performance 2-axis MEMS Digital Inclinometer

Definition: High-performance 2-axis XY MEMS digital inclinometer, designed for high-precision tilt measurement.

Key Parameters

- Measuring Axes: X/Y 2-axis tilt

- Measurement Modes (selectable via software, one of two):

  - Mode A: ±30° (0.5g), low-pass filter 10Hz

  - Mode B: ±90° (1.1g), low-pass filter 40Hz

- Resolution: Up to 32768 LSB/g

- Noise Density: As low as 0.0009°/√Hz, ultra-low noise

- Long-term Zero Drift: Typical ≤0.05° (over full product lifetime and temperature variation, excellent stability)

- Supply Voltage: 3.0V ~ 3.6V (typical 3.3V)

- Communication Interface: SPI digital interface

- Operating Temperature: -40℃ ~ +85℃

- Package: DFL-12, dimension 8.6 × 7.6 × 3.3 mm, SMD surface-mount package

- Technology: Murata 3D-MEMS capacitive sensing technology, factory pre-calibrated

## Functions

1. Direct 2-axis tilt angle output; tilt value can be read directly without complex algorithms.

2. Two range/bandwidth modes switchable by software, suitable for low-speed high-precision or large tilt angle applications.

3. Built-in advanced self-diagnosis function to verify sensor signal reliability in real time.

4. Excellent vibration and shock resistance, minimal zero drift under wide temperature range.

5. Factory pre-calibration reduces calibration workload on customer production lines.

 Applications

- Structural Health Monitoring (SHM): Tilt and settlement monitoring for bridges, dams, transmission towers and buildings

- Industrial leveling & platform stabilization: Construction machinery, laser equipment, surveying instruments, antenna leveling

- IMU inertial measurement units, positioning and navigation systems

- Tilt monitoring for construction machinery and photovoltaic brackets

- Geological monitoring, tunnel deformation monitoring
