HCA396B HIGH ACCURACY INCLINOMETER SENSOR MODULE ▶ PRODUCTION HCA396B is a three-axis high-precision inclinometer sensor developed by RION, which is used in industrial engineering industries such as foundation pit inclination, monitoring, and bridge inspection. Inheriting the stability of the HCA series, the accuracy is effectively improved, the temperature drift performance is superior, and the long-term stability is less than 0.001 degrees. At the same time, through the 5th-order filtering algorithm, the roll angle and pitch angle of the sensor can be solved by the 3-axis gravity compound operation....

HCA396B HIGH ACCURACY INCLINOMETER SENSOR MODULE ▶ WORKING PRINCIPLE The core control unit imported from Europe is adopted, and the principle of capacitance miniature pendulum is adopted. Using the principle of gravity of the earth, when the tilting unit is tilted, the earth's gravity will produce a component of gravity on the corresponding pendulum, and the corresponding capacitance will change. After the capacitance is amplified, filtered, and converted, the tilt angle is obtained.

HCA396B HIGH ACCURACY INCLINOMETER SENSOR MODULE ▶ INSTALLATION Install the sensor mounting surface parallel to the target surface to be measured and reduce the effects of dynamics and acceleration on the sensor. Please refer to the following diagram for the installation method: Note: The left 1 is a schematic diagram of the product coordinate system direction; the right side is the sensor measurement direction diagram, ±X indicates the angle of rotation around the X axis, and ±Y indicates the angle of rotation around the Y axis. The X and Y angle directions satisfy the right-hand rule.
