Product Description

HDA446T A new generation of digital MEMS dynamic tilt sensor. It can measure the attitude parameters (roll, pitch, and azimuth) of a moving carrier, and suitable for tilt angle measurement under motion or vibration.HDA446T has a built-in high-precision acceleration and gyro sensor, and integrates the Kalman filter algorithm, which can measure the real-time motion data of the carrier under motion or vibration. The signal output modes such as RS485 / RS232 / TTL are optional, and the scalability is strong.

This product adopts non-contact measuring principle, which can output the current attitude and inclination in real time. It is simple to use and does not need to retrieve the relative changes of the two surfaces.Internally integrated high-precision AD and high-precision gyro units to compensate for non-linear, orthogonal coupling, temperature drift and centrifugal acceleration in real time; greatly eliminate centrifugal errors caused by motion acceleration interference, improve product dynamic measurement accuracy; adapt to long-term complex movements Work in places and harsh environments.The product is a dynamic and static dual-mode measurement sensor with strong resistance to external electromagnetic interference.It is suitable for all kinds of large-scale and high-strength shock and vibration industrial environments, and is an ideal choice for industrial automation control and measurement of attitude.

1)Accuracy: refers to the root mean square difference between the measured and actual angle value by multiple measurements (>16 times) under normal temperature.

2)Zero temp.drift coefficient: the change rate of the indication value relative to normal temperature within the rated operating temperature range of the sensor at the zero degree.

3)Sensitivity temp.drift coefficient: The percentage change rate with temperature of the full-scale indication relative to the full-scale indication at room temperature of the sensor in its rated operating temperature range.
