The HDA446T product is a new generation of digital MEMS dynamic tilt sensor, which can measure the attitude parameters (roll, pitch, and azimuth) of a moving carrier and is suitable for tilt measurement in motion or vibration states. The HDA446T is equipped with built-in acceleration and gyroscope sensors, and integrates the Kalman filter algorithm to measure real-time motion data of the carrier under motion or vibration conditions. The product has dual CAN (CAN2.0A/CAN2.0B) modes and strong scalability.
This product adopts non-contact measurement principle , it can output the current posture inclination angle in real time. It is easy to use and does not require retrieving the installation of two surfaces with relative changes. Internally integrated high-precision AD and gyroscope units can compensate for nonlinearity, orthogonal coupling, temperature drift, and centrifugal acceleration in real time, greatly eliminating centrifugal errors caused by motion acceleration interference, improving product dynamic measurement accuracy, and adapting to work in complex motion scenes and harsh environments for a long time. This product belongs to the dual-mode measurement sensor of dynamic and static, with strong resistance to external electromagnetic interference. It is suitable for various large-scale high-intensity impact vibration industrial environments and is an ideal choice for industrial automation control measurement posture.
