Description

Technical Field

[0001] This utility model relates to the technical field of gyroscope anti-roll devices, and in particular to an angle sensor and a gyroscope anti-roll device. Background Technology

[0002] Gyroscopic roll reduction devices utilize the self-stability of a gyroscope to control the precession of a high-speed rotor, thereby reducing ship roll. An angle sensor is a device that detects changes in the precession angle and converts them into an electrical signal. Common non-contact angle sensors suffer from poor concentricity between the magnetic block and the chip, and are inconvenient to install. When the magnetic block and chip of the angle sensor are not concentric, the measured precession angle will be inaccurate, affecting the roll reduction effect of the gyroscopic roll reduction device.
