The stainless steel float switch uses magnetic force to operate, has no mechanical connectors, and is simple and reliable to operate. When the measured medium of the float switch floats, the float drives the main body to move, and the magnet at the other end of the float controls the magnet on the switch action rod. The following is an introduction to the working principle of the stainless steel float switch.
Liquids have buoyancy, and the float system (generally with corresponding auxiliary equipment) is made according to the buoyancy of the liquid. When the liquid level rises, the float system also rises accordingly. Similarly, when the liquid level drops, it also drops accordingly. When it rises or drops to the set position, the float system will hit the travel switch (or other microelectronic equipment) at the set position, causing the travel switch to send an electrical signal, and the electronic control equipment will immediately act when receiving the electrical signal, cutting off or connecting the power supply to form an automatic control system, which is basically a reed switch structure. There is a movable float on the outside with a magnet inside the ball. When the magnet is approached to the reed switch by buoyancy, the contacts in the reed switch are connected or disconnected. The principle of the reed switch is that like magnetic poles repel each other and unlike magnetic poles attract each other. The switch of the reed switch in the liquid level switch controls the corresponding operating mechanism, forming a complete set of circuits, such as: liquid level display, automatic liquid inlet, liquid full alarm, etc.
