Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a magnetic ring detection equipment. Background Art

[0002] There are many types of magnetic rings, including TMR magnetic rings and other magnetic rings. TMR magnetic rings are mainly used as components in high-sensitivity sensors. They are used to detect weak magnetic fields and sense weak magnetic field signals. Because this type of high-sensitivity sensor is small in size, high in reliability, and has a wide corresponding range, it has broad application prospects in automation technology, household appliances, trademark recognition, satellite positioning, navigation systems, and precision measurement technology. High sensitivity means that the intensity of the detected signal is getting weaker and weaker, which requires a great improvement in the sensitivity of the magnetic sensor. Specific applications include current sensors, angle sensors, gear sensors, space environment measurement sensors, etc. The current sensor needs to detect nA-level currents. Even with a serrated ring, the detection accuracy of the magnetic sensor itself needs to reach the nT level. The angle sensor requires a resolution less than 0.01. The gear sensor requires the refinement of the gears and the maximization of the distance between the sensor and the gear, which causes the magnetic signal to become very weak. For space environment measurements, the resolution needs to be less than 0.02pT. Therefore, improving the accuracy of magnetic rings, especially TMR magnetic rings, is of great significance to improving the sensors containing the magnetic rings. The existing technology mainly relies on manual detection, and there is no detection equipment for magnetic rings. Utility Model Content
