Installation of sensors in well and on the top of car

The structure of change speed sensors is the same with that of levelling sensors, which consist of plastic box, permanent magnet and inductor. The sensors are equivalent to the permanent-magnet relay, the structure and working principle are shown in figure 15-4. Fig. a indicates that before magnet 3 is put into sensor, the make contacts (normally open) 6、7 is open, and the break contacts (normally closed)7、8 is close because external forces are not put on inductor 2. Fig. b indicates after permanent-magnet 3 is put into sensor, the make contacts (normally open)6、7 is open, the break contacts (normally closed)7、8 is close, which is equivalent to the condition that electromagnetic relays gain power supply to work. Fig. C indicates that if an iron plate with high-magnetic permeability (magnet-proof plate) enters between permanent magnet and inductor, the contacts of inductor will return to the state a without external forces because the magnetic field made by permanent magnet is shunted by the magnet-proof plate.
