High-Precision 0.01° Dynamic Inclinometer for Accurate Measuring and Analysis
▶ PRODUCT DESCRIPTION
HDA436T/HDA437T A new generation of digital MEMS dynamic tilt sensor launched by RION
Technology. It can measure the attitude parameters (roll, pitch, and azimuth) of a moving carrier, and
suitable for tilt angle measurement under motion or vibration.HDA436T has a built-in high-precision
acceleration and gyro sensor, and integrates the Carman 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.
