▶ PRODUCT DESCRIPTION
HDA436T/HDA437T is a new generation digital MEMS dynamic tilt
sensor launched by RION Technology. It accurately measures the
attitude parameters (roll, pitch, and azimuth) of a moving carrier,
making it suitable for tilt angle measurements during motion or
vibration. The HDA436T is equipped with a high-precision
accelerometer and gyro sensor, integrated with a Kalman filter
algorithm for real-time motion data measurement under dynamic
conditions. It offers optional signal output modes including RS485,
RS232, and TTL, ensuring strong scalability.
This product operates on a non-contact measuring principle,
providing real-time output of current attitude and inclination
without the need to track relative changes between surfaces.
Internally, it integrates high-precision AD converters and gyro
units to compensate for non-linearities, orthogonal coupling,
temperature drift, and centrifugal acceleration in real-time. This
greatly minimizes centrifugal errors caused by motion acceleration
interference, thereby enhancing dynamic measurement accuracy.
The sensor is designed for robustness, featuring dual-mode
measurement capabilities (dynamic and static) resistant to external
electromagnetic interference. It is ideal for industrial automation
control and precise attitude measurements in environments
characterized by large-scale operations and high-intensity shock
and vibration.
