When the liquid level rises, the floating ball also rises accordingly. Similarly, when the liquid level drops, it also falls accordingly. When it rises or falls to the set position, there is a magnet inside the ball. When the magnet is close to the internal switch due to buoyancy, the contacts in the switch are connected or disconnected. The principle of the switch is that like magnetic poles repel each other and different magnetic poles attract each other. The switch in the liquid level switch controls the corresponding operating mechanism, forming a complete set of circuits.
Product Introduction
Level Sensors are mainly used in the manufacturing and automotive industries, and can also be found in many Home Appliances, such as the ice maker in the refrigerator, the washing machine needs to prevent the liquid level from being too high and excessive water overflowing, the water heater needs to detect that the liquid level in the internal water tank is too low and automatically replenishes water, the toilet needs to keep water in the water tank, etc.
