Float switches briefly explained:
Float switches, also known as level or liquid sensors, offer precise monitoring of liquid levels in tanks, containers, and systems. In the world of industrial automation, they have become a proven technology. Whether it’s about preventing overfilling, triggering alarms at low liquid levels, or controlling pumps, our float switches provide a reliable solution.
The operating principle of a float switch based on reed contact relies on using a reed contact as the switching element. A float switch consists of a buoyancy body, also known as a float, which floats on the liquid surface. The buoyancy body is equipped with a magnet.
As the liquid level changes, the buoyancy body moves correspondingly up or down. Upon reaching a specific level, the magnet approaches the reed contact. The reed contact comprises two ferromagnetic contact blades enclosed in a glass capsule. These blades are separated by a small air gap.
When the magnet of the buoyancy body reaches the reed contact, the magnetic field attracts the ferromagnetic blades and brings them together. This closes the contact blades and completes an electrical circuit. This closed circuit can be used to send a signal, such as triggering an alarm or controlling a motor.
Industrial Automation Technology
In industrial automation, float switches are indispensable for precise monitoring and control of liquids. Whether in cooling systems, hydraulic systems, or the food industry, they ensure smooth operations through exact control and prevent damage. A key application area is pump control: here, float switches monitor the liquid level and automatically switch pumps on or off, improving their efficiency. In the machinery and automotive industries, oil level monitoring ensures smooth operation and optimal lubrication of engines and gearboxes.
