HDA446T Dynamic Tilt Sensor for Heavy Machinery, Railway and Marine Attitude Monitoring

Reliable Attitude Measurement in Motion and Vibration

In industrial environments, equipment often operates under continuous movement, vibration, and changing working conditions. Accurate attitude measurement is essential for monitoring equipment orientation, improving operational awareness, and supporting automated control systems.

The RION HDA446T Digital MEMS Dynamic Tilt Sensor is designed to measure the roll, pitch, and azimuth of moving carriers. By integrating high-precision accelerometer and gyroscope units with a Kalman filtering algorithm, the sensor provides real-time attitude data for dynamic and static measurement applications.

Advanced Dynamic Tilt Measurement

Unlike conventional static tilt measurement solutions, the HDA446T is designed for applications where equipment is moving or experiencing vibration. Its integrated measurement and compensation technology helps reduce errors associated with motion acceleration, temperature drift, nonlinear characteristics, and cross-axis coupling.

This makes the HDA446T a suitable solution for industrial systems that require reliable attitude information under complex operating conditions.

Key Features of the HDA446T

• Wide measurement range: Roll ±180°, pitch ±90°, and azimuth ±180°.

• Dynamic accuracy: ±0.1° for roll and pitch.

• Static accuracy: ±0.05°.

• Flexible communication: Optional RS485, RS232, or TTL output.
