The invention relates to an angle sensor with adjustable measurement precision. The angle sensor comprises a mounting plate and a shell. The bottom surface of the mounting plate is provided with an annular flange. The top end of the shell is detachably arranged on the annular flange through threads. The shell is internally provided with a circuit substrate which is provided with a magnetic sensor and an angle sensing device. A dial is arranged above the circuit substrate and is uniformly provided with at least one electromagnetic induction zone with a same central angle along a circumferential direction. The magnetic sensor is used for sensing the magnetic field generated by the electromagnetic induction zone and generating a corresponding angle sensing signal. The angle sensing device is used for receiving the angle sensing signal generated by the magnetic sensor. The upper surface of the dial is also provided with a precision control device and a battery. The precision control device is used for selectively magnetizing the electromagnetic induction zone. The shell is internally provided with a spindle. The bottom end of the spindle is fixedly arranged at the middle part of the upper surface of the dial. The top end of the spindle passes through the mounting plate and protrudes out of the top surface of the mounting plate.
Description
technical field [0001] The invention relates to a sensor, in particular to an angle sensor. Background technique [0002] As the name implies, an angle sensor is a sensor used to measure the rotation angle of a rotating shaft, and is widely used in the field of mechanical automation. Existing angle sensors generally include a light emitter, a light receiver, and an angle disk. Scale holes are evenly spaced on the angle disk. The light emitted by the light emitter is received by the light receiver through the scale holes to measure the angle of rotation. Since the interval between the scale holes on the angle plate cannot be changed after the manufacture is completed, the measurement accuracy of the existing angle touch sensor cannot be adjusted, and it is difficult to be suitable for different application occasions. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating in order to create a new structure of the angle sensor, so ...
