Magnetic sensors are devices that use magnetic materials as sensitive components, and their detectors are magnetic probes. When an object made of ferromagnetic metal enters the static magnetic field formed by the magnetic probe, it will induce a new magnetic field, interfere with the original static magnetic field, cause the magnetometer pointer to deflect and swing, generate electrical signals, and thus achieve the detection of the object. In bulldozers, magnetic sensors can be used to measure parameters such as speed and displacement, for example, by sensing magnetic field changes in gear tooth tips and valleys to measure the speed of the drive shaft.

A magnetic switch is induced by a magnet. When a magnetic substance approaches, the two internal spring plates will be magnetized and attracted to each other, connecting the circuit; When there is no magnetism, the circuit is disconnected. It can be used to detect the state of mechanical motion or circuits. In bulldozers, magnetic switches can be used to detect the opening and closing status of the cab door, as well as in systems such as fuel level indicators, safety switches, and power steering. For example, the fuel level can be determined by detecting the position of the magnet on the float.
