Magneto-dependent sensor and manufacturing technology thereof

Abstract

The invention discloses a magneto-dependent sensor and a manufacturing technology thereof. The magneto-dependent sensor comprises a shell, a floater, a permanent magnet, a limiting ring, a GPS positioning device, a reed switch, a limiting block and a rotary sliding sleeve. The manufacturing technology is simple; due to the fact that the shell is filled with resin, a magneto sensitive element inside the shell can be stabilized and protected, the magneto sensitive element and a wire are prevented from making contact with water, the stability of the magneto-dependent sensor is improved, and the service life of the magneto-dependent sensor is prolonged. The floater is made of aluminum materials, the surface of the floater is provided with an oxide layer, and therefore the service life of the floater is prolonged. The position of the magneto-dependent sensor can be positioned in real time by arranging the positioning device and an emitter, and people can be remained to carry out maintenance in time once the position is changed. The wire harness maintenance cost can be reduced by arranging a connecting sleeve. Wire harnesses can be fixed into a whole by arranging a sliding plate and a sliding groove. The overall wiring structure is more attractive, and wire harness maintenance and replacement are quite convenient when some wire harnesses go wrong.

Description

technical field [0001] The invention relates to a sensor and a manufacturing process, in particular to a magnetic sensitive sensor and a manufacturing process thereof. Background technique [0002] Equipment in daily life needs to monitor the water level, such as washing machines, air conditioners, etc. The magnetic sensitive water level monitors in the prior art have short service life, poor water immersion pressure resistance, and are prone to problems such as reduced sensitivity and even failure to work after long-term immersion in water; the existing magnetic sensitive water level monitors have complex structures and are inconvenient to maintain; at the same time The function is single, and the service life of the float is short. Contents of the invention [0003] In order to solve the above problems, the present invention provides a magnetic sensor and its preparation process. [0004] In order to achieve the above object, the technical scheme that the present inven...
