Mini float switches are small yet powerful sensors that can be used for precise level measurements in a variety of industries. They are specially designed for use in tight spaces. Their compact construction allows them to be easily installed in small containers and systems. They enable precise level measurements, even in narrow spaces where conventional sensors reach their limits.
The operating principle of a float switch based on a reed contact relies on the use of a reed contact as a switching element. A float switch consists of a buoyant body, also known as a float, which floats on the liquid level. The buoyant body is equipped with a magnet.
As the liquid level changes, the buoyant body moves up or down accordingly. When it reaches a certain level, the magnet approaches the reed contact. The reed contact consists of two ferromagnetic contact blades placed inside a glass bulb. These blades are separated by a small air gap.
When the magnet of the buoyant body reaches the reed contact, the magnetic field attracts the ferromagnetic blades and brings them together. This action closes the contact blades, completing an electrical circuit. This closed circuit can be used to send a signal, such as triggering an alarm or controlling a motor.
- Precise Level Monitoring: Mini float switches allow you to monitor the level of your liquids precisely. Thanks to the reed contact, they provide reliable and accurate measurements to prevent overfilling or underfilling. This enables you to control your processes optimally and effectively prevent operational disruptions or production downtime.
- Versatile Applications: The applications of mini float switches are nearly limitless. Whether in shipbuilding, petrochemicals, mechanical engineering, or the food industry, mini float switches can be used in various industries. Their compact design allows for installation in confined spaces and tanks with limited space.
